Like the kūpuna, or ancestors, before her, “I create a product that I just give away,” says Gaisoa, 49. So, “I expect you to stand on the front line when I have to fight for this.”

Gaisoa belongs to one of 22 Kānaka ʻŌiwi (Native Hawaiian) ʻohana, or families, tasked with farming salt for centuries. Tradition dictates that their salt can’t be bought or sold—only traded or given. But in the 21st century, the flats grapple with modern problems, such as pollution and erosion. And contrary to Indigenous customs, a Hawaiian salt-farming industry has developed, with businesses marketing the product around the globe. 

However, Gaisoa isn’t threatened by the corporate farms because they’re often motivated by profit, not cultural preservation, she says. “There’s nothing to compare.”

The Hanapēpē salt ponds are a place of legend. According to Gaisoa, they were discovered one day after a local woman went fishing and caught too many. Because Hawaiians hunt and gather in moderation, she walked the coastline, trying to give her extra fish away. When she couldn’t, she started to cry. At the same time, Pele, the Hawaiian goddess of fire and volcanoes, was visiting her brother, Kāmohoaliʻi, the shark god. Appearing from the bushes, Pele led the upset woman to the flats to teach her the art of making salt.

When Gaisoa first visited the salt patch with her father Frank Santos in her youth, she hated the activity. But once her two children, Waileia Tafiti and Piilani Kali, were born, she wouldn’t let them miss a day at the flats.   

There, each ʻohana maintains its own section. Located on the island’s south shore, the area floods during the winter, and only once it dries do the salt makers begin cultivating. Salt season is weather-dependent, but it usually takes place from May to August. 

Salt water travels underground into nearby wells, which can range from 10 to 15 feet deep. Every summer, the practitioners use buckets to remove the water, then scrape the wells’ inside walls to promote water flow.   

“You literally have salt crystals on your skin—that’s how salty the water is,” says Gaisoa. Brine shrimp also help clean the wells and sweeten the salt’s taste.

The kiaʻi, or stewards, dig for black clay, then use rocks to mold it into salt beds, which measure between three and four feet wide and eight and 10 feet long. Afterward, they bake in the sun. The entire process takes between four and six hours. After well water is poured into the bed, it crystallizes, forming layers of salt flakes. 

The fresh white salt sits at the top and is used as seasoning. The pink salt in the middle is given away, and the red salt at the bottom serves religious and medicinal purposes.

In the days of yesteryear, salt makers would give five-gallon buckets to those who asked, but, today, it’s typically limited to one gallon. They still barter with salt, and they have even auctioned it for noble causes. However, Gaisoa doesn’t judge the few who sell their goods.

“It’s expensive to live in Hawai‘i,” she says. “If someone is selling it on the sidelines, well, you gotta do what you gotta do.”

And 2023 counted as a bad year for salt makers. “I’m not giving out any more because I don’t have any,” says Gaisoa. “There’s only been another time in my lifetime where there was a salt shortage.”

They’ve faced other problems in recent years. During the COVID-19 pandemic, county officials moved a group of unhoused people to the adjacent Salt Pond Beach Park, and their excrement contaminated the salt flats. Today, partiers who gather in their parking lot leave trash behind. Cars driving on the beach contribute to sand erosion. A 1960s-era road built by the government through the patch is now corroding, and the salt makers are working on a plan to address it. 

When the aircraft of a helicopter tour agency, Maverick Helicopters, flies overhead, they blow dust into the salt. Since 2019, Hui Hana Pa‘akai o Hanapēpē—a Kānaka ʻŌiwi nonprofit that represents the salt-farming ʻohana—has fought the company’s expansion efforts because the potential for noise, chemical runoff and pollution threatens the harvest. 

“My goal before I die is to get rid of the helicopter landing pad,” says Gaisoa. “At the end of the day, people just need to be respectful of the area.”

Malia Nobrega-Olivera, 52, also belongs to a salt-making ‘ohana in Hanapēpē. She highlighted several large-scale action points to better support them, including properly citing Indigenous elders and establishing prior and informed community consent.

At Keāhole Point on Hawai‘i, Kona Sea Salt Farm also deals with external challenges, such as strong winds and storms. During the winter, the team struggles to keep up with demand because weather slows its production. 

“Mother Nature always has the last word,” says Melanie Kelekolio, operations general manager and chief salt maker. Although the business sells its salt on the islands, the continental US and Japan, it still uses hands-on methods under Kelekolio’s leadership.

In 1999, she started at the nearby Natural Energy Laboratory, first growing microalgae before exploring salt production as a side project in 2004. Intrigued at the idea of making salt out of deep sea water, Kelekolio and a maintenance worker dug holes by hand to create their first hot house. 

Since then, trial and error has fine-tuned the oceanfront salt farm’s methodology. Now, a 40-foot pipe extending 2,200 feet deep into the ocean sends water into the operation’s solar evaporation beds. Those tunnels are covered, letting moisture evaporate under the sunlight before the salt is harvested.

“We can’t be totally traditional” and make salt in open ponds, says Kelekolio, 56. “It’s not as clean as it would have been 100 years ago.” 

And in order to sell their salt as food, the farm—owned by Sea Salts of Hawai‘i – also has to follow Food and Drug Administration regulations, which wouldn’t allow for the customary process.

The business is trying to move away from using plastic materials, although “the challenge is finding surfaces that can withstand the heat and the scope—the corrosiveness of sea salt,” says Kelekolio.

Her team has expanded to include seven full-time employees, several part-time workers and event staff—mostly kamaʻāina, or born in Hawai‘i. That aspect means “they totally appreciate the fact that we are still continuing something that is still an important part of the Hawaiian culture,” says Kelekolio.

She recognizes that they aren’t following local custom by selling their salt. But Kelekolio sees products mislabeled as Hawaiian salt at grocery stores, and she’s proud that she and others with Kānaka ʻŌiwi lineage are the ones behind their product made in Hawai‘i.

“We are actually located in a place where salt was traditionally harvested 100 years ago,” says Kelekolio said. “It really is helpful that you have Kānaka to carry it on.”

There was just one problem: Lewis and Barker could not afford to buy the farm or the land on which it sits—that is, until they worked with an agricultural land trust.

What is a land trust?

Land trusts can be non-profit conservation organizations or, in some instances, government bodies that work to conserve agricultural land in perpetuity.

Without farmland to grow crops or ranchland for livestock, we don’t eat. Conserving farmland underpins a stable local food supply. Without agriculture, jobs are lost; 22.1 million full- and part-time jobs were related to the agricultural and food sectors in 2022, which equals 10.4 percent of the total US employment. Keeping farmland in farming is crucial for our food supply and food security, and it’s why the American Farmland Trust (AFT), a national conservation organization, advocates for keeping farmers and farmland together. 

The ATF predicts that more than 300 million acres of farmland and ranch land could change ownership within the next two decades, with some of it transitioning out of agriculture use permanently. As retiring farmers exit the field, they are looking to the equity they’ve built up in their land on which to retire. That can be a significant sum, something that young or new farmers may not be able to afford. (According to the USDA’s 2022 Census of Agriculture, farmers under the age of 35 account for only nine percent of all producers.) But real estate developers can afford it. 

“Between 2001 and 2021, the country lost 11 million acres of agricultural land,” says Jen Dempsey, director of the Farmland Information Center and senior advisor for the AFT. “Development,” she says, “remains the most significant and direct threat to farmland.” 

Ben Miles, is the Southeast Program manager for Land Trust Alliance (LTA), a member organization with 950 land trusts nationwide. “Most farmers and ranchers could find a buyer willing to purchase their property and develop it, whether into 10-acre ranchettes or 1/8-acre lots,” he says. 

A land trust is able to purchase land outright, remove the development potential and then lease or sell the land back to a farmer. It is also able to help a beginning farmer if the selling price being asked by an existing farmer is too high. 

Community land trusts retain ownership of the property while the farmer pays a tenancy back to the trust to farm the land. But this can be a mixed bag. The farmer owns the buildings and the equipment, but not the land. 

[RELATED: Q&A: How Community Land Trusts Help to Preserve Farmland]

“Farmers look at their property values going up to retire,” says Lewis. Without value in the land, it becomes difficult for the farmer to gain equity or retirement savings. 

How do land trusts work?

By far the most popular way a land trust works is through the purchase of a conservation easement: a legally binding agreement between a land trust and a property owner, designed to keep farms and ranches conserved for agricultural use in perpetuity. 

The land is first appraised without any conservation restrictions placed on it. This is generally the higher value of the land with zoning and development potential attached to it. It is then appraised with conservation restrictions placed on it. The difference between the two values represents the “easement” value of the property. In 2022, the AFT and the USDA Natural Resources Conservation Service sent out a survey to land trusts across the US. The majority of respondents to the survey, 88 percent, reported conserving 5.9 million acres of farmland and ranchland through conservation easements. 

In the case of Oyster Bay, the former owners sold the easement value of the property to Community Farmland Trust. They were then able to retire, having leveraged the equity in their property. Lewis and Barker were able to buy the more affordable property without the development rights attached. Since 2018, they have been producing and selling free-range chicken eggs and meat on the farm’s idyllic 40 acres.

“The fee interests—the dirt, the soil, the property—are in our names,” says Lewis, while the conservation easement is in the land trust’s name. The property owner, in this case Lewis and Barker, retains ownership and usage of the land—such as the right to continue farming or to raise livestock. The legal agreements governing an easement are extremely comprehensive including the buying and selling of the farm property. “Easements can be amended and altered slightly, but it can be a very challenging process,” says Lewis. As a general rule, once the land is conserved and the easement filed with the land records office, it is binding and travels with the property for all current and future owners. Even if Lewis and Barker sell the property, the conditions and restrictions on the easement remain in place forever. 

But nothing is perfect. “The easement in our situation reduced the overall cost of the initial purchase in 2018, but now, as property values overall have risen, the land is worth almost the same as before the purchase,” says Lewis.

This is a concern for Lewis and Barker, as they wonder what will happen when it’s their turn to retire and pay the land forward. Their daughter currently does not want to farm. So, will the property again become unaffordable?

Lewis also cautions that land trusts can be complicated legal quagmires and that those entering into a trust should have tempered expectations. Lease agreements, inheritance regulations and the shared responsibility of land stewardship between the trust that owns the land and the farmer can take time to work out. It took Lewis and Barker more than three years to finally have everything in place. All three parties involved (the sellers, the land trust and Lewis and Barker) needed to work out the details of the sale and conservation restrictions being placed on the land. The land trust had to do land surveys and environmental assessments to obtain a grant that let them purchase the easement. “It all takes time,” says Lewis.

How can farmers get started with land trusts?

For farmers looking to conserve their land in a trust and for young agrarians interested in acquiring farmland, the AFT’s Land Transfer Navigators program in partnership with the USDA Natural Resources Conservation Service is a good place to start.

“Some land trusts,” says Miles, “also have programs connecting new farmers with retiring farmers, through Farm Link programs, or run incubator or community farms, so they may be able to directly help new farmers get access to land and to get their business started.”

Land access and the ability of young farmers to be able to purchase land is a pressing problem that could be addressed in the upcoming Farm Bill. The Increasing Land Access, Security and Opportunities Act is one of several bipartisan bills addressing the issue. Led in the House of Representatives by Joe Courtney (D) from Connecticut, Zach Nunn (R) from Iowa and Nikki Budzinski (D) from Illinois, it hopes to prioritize projects that give direct financial assistance to farmers, involve collaborative partnerships and transition farmland from existing producers to the next generation.

“We are in a land access crisis,” says Lewis. “As farmers get older and look at how they can retire, we need all the options on the table.”

Correction: An earlier version of this story stated that land trusts are legal agreements administered by non-profit conservation organizations. The conservation easement is the legal agreement, while the land trust is the organization that holds or owns the easement.

Witt’s home in South Egremont is a scant mile from Indian Line Farm, the nation’s first CSA; together, the pair of plots represents 28 total acres stemming from another of Witt’s passion projects. Since her founding of the nonprofit in 1980, the Community Land Trust in the Southern Berkshires (CLTSB) has been creating lease agreements throughout the region, aimed at enabling occupants to build wealth (including equity in their improvements) on community-owned land—with the goal of creating an equitable, regenerative future for all. 

We spoke with Witt about the role community land trusts stand to play in the future of farming, especially as access to affordable farmland continues to dwindle. This interview has been edited for length and clarity.

HVS: Let’s start with the basics. What is a community land trust?

SW: A CLT is a nonprofit, regionally based organization with open membership that acquires land, by gift or by purchase, creates a land-use plan that reflects needed land use in the community—from creating workforce housing and securing low-cost land access for farmers to keeping retail space locally owned—and embeds social and ecological objectives for each site.

HVS: How does a community land trust differ from a conservation land trust? 

SW: While conservation land trusts focus on keeping lands in their natural state, the CLT model deals with working lands. Its goal, to take the cost of land out of access to it, is achieved by leasing community-owned land at a very affordable rate for purposes described in a land-use plan. 

Community land trusts are organized to give equity in buildings and other improvements on the land, which are owned by the lessee, while conservation land trusts generally exclude housing and/or other buildings. 

[RELATED: Holding onto Farmland, One Land Trust at a Time]

HVS: What does this community-based approach aim to do?

SW: Achieving long-term security for farmers is among the biggest benefits of community land trust ownership of farmland. A lease, coupled with ownership of outbuildings and improvements including soil improvements, means farmers own all of what they put into their operation. When compared with handshake agreements and short-term leases, this model ultimately positions farmers to apply for grants unavailable to those without land security. 

Preserving farmland in perpetuity is another major benefit. Take Indian Line Farm, for instance: when founder Robyn Van En died unexpectedly in 1997, that farm could have easily been sold as another second, third or fourth home in the Berkshires, and a prime, fertile tract of bottomland for local agriculture would have been lost. Instead, the local community land trust raised donations to purchase the land value; the Nature Conservancy (which owned abutting wetlands) purchased an overall easement; and two local farmers—who had been working the land but lacked the assets to purchase the farm— took out a mortgage to buy the buildings. They have since paid back the debt of the mortgage; improved the house and the barns; built greenhouses and have a thriving business that provides food to local markets and consumers. 

HVS: What are the roadblocks here? What’s keeping more land from being used in this way?

SW: There’s a lot of farmland out there, much of which is tied up by easements and commodity crops—which neither fosters access for the small, diversified farms needed to strengthen the local food web nor does it enable housing on site for the farmer, which is critical. When farmland and housing are combined, it creates a farmstead providing land security and housing security for our small farmers. We’d like to encourage more cooperation between community land trusts and conservation land trusts in securing farmsteads. Conservation land trusts can play a key role in developing land-use plans with ecological considerations.

HVS: What can people do in their own communities to address this issue? 

SW: While the importance of donating “the back forty” (a remote piece of land that has yet to be cultivated) to conservation land trusts is well understood, we seek to encourage the same understanding of how to make donations of working lands—with buildings—to community land trusts. This practice allows donors to remain aligned with their priorities (to help local growers bolster the food supply, for instance) rather than risk leaving property to another type of nonprofit [that] might sell the donated land and buildings to the highest bidder in order to raise cash for other uses. It’s pretty powerful. 

HVS: What can I do today? 

SW: Learn how local land trusts are leading the way in conservation by discovering the active land trusts in your state. Join your community land trust and be a voice there. For a modest annual fee, everyone is welcome to exercise their civic engagement and participate in a community-led solution.

Conservationist Eric Steen aims to change that. His Earth to Beer project is bringing together over 35 breweries from across the US to make a commitment to brewing a mindfully sourced and packaged beer in collaboration with local environmental nonprofits this Earth Day, “to pack as much sustainability as possible into each can.”

As the impacts of climate change intensify worldwide, there is a greater awareness that we need to make changes in our daily lives to help combat its effects. With this project, Steen is enabling breweries and drinkers to do this in an open-ended and collaborative fashion. “What I think is truly unique about Earth to Beer is that we don’t prescribe a specific way to approach the environmental question,” Steen explains. “We aren’t telling brewers to buy organic only, we’re saying that organic is one of many great options that also include local, regenerative agriculture, other certifications like Salmon-Safe, non-certified but responsibly grown, and more. This decentralized approach allows breweries to get creative in ways that make sense for them, their budgets, and their communities.”

Steen aims to make the project as accessible as possible for breweries and drinkers, offering negotiated discounts with suppliers, information about ethical sourcing, and marketing and branding resources and custom artwork to help breweries attract interest from customers and retailers. Brewers can make any style of beer and use whichever sustainable resources they feel will suit their needs best. Recipes released already include Aslan Brewing’s classic Amber Ale, which uses all Salmon-Safe certified hops, and GearHouse Brewing’s Imperial Honey Wheat Ale brewed with Pennsylvania honey and aged in locally sourced whiskey barrels.

Earth to Beer features participants from Alaska to Texas to Hawaii, all of whom have committed to working with sustainable suppliers and partnering with a local environmental nonprofit. “We’ve asked breweries to reverse the role of what normally happens with a nonprofit — usually the nonprofit approaches the brewery and there’s a pretty hands-off way of giving donated beer for a cause. In Earth to Beer, breweries have to find a nonprofit they want to work with, do the outreach and invite them in” says Steen.

Oddwood Brewing in Austin TX has chosen to partner with the Colorado River Alliance for the project. “With good, clean water being absolutely crucial to the creation of good beer we, as a small community-oriented brewery, wanted to team up with those that are fighting to protect our water and communities,” says Oddwood’s events and operations manager Charlie Mikulich. Oddwood is also sourcing its malt from TexMalt, a locally based supplier that works with nearby farms to reduce the carbon footprint of malt supply. It is also sourcing from Yakima Chief Hops, a grower-owned family farm collective that uses green energy to power its facilities, a water reclamation program to keep local habitats safe, and created the Green Chief Program (a sustainability management program that promotes and develops guidelines for all their farms). 

Breweries are required to pay a small fee to join Earth to Beer and make a contribution to the nonprofit of their choice, depending on brewery size, ranging from $500-$1,000 minimum. They are also expected to begin open-ended collaborations, such as providing beer for events and offering free meeting spaces. For startups and minority-owned breweries, sponsor Arryved, which specializes in point-of-sale technology, has provided a stipend so cost doesn’t prohibit participation. “Building a better world through beer requires not only more sustainable ingredients and processes, but also more opportunities for people of color to participate and contribute to the creativity and problem solving we will need to get there,” says Aaron Gore, Director of Community and Partnerships at Arryved.

Another sponsor and collaborator is Canworks, the first US company to print directly onto aluminum cans, eliminating plastic waste and making them recyclable. “There is a challenge in consumer awareness. Most consumers don’t realize that many of the cans they recycle are covered in shrink sleeves and those cans are going straight to a landfill because of that,” says Canworks head of marketing Daniel Rigdon. That’s where Earth to Beer comes in. “Educating consumers so they can make informed decisions is the fastest way to effect change,” Rigdon explains.

Steen aims to spearhead wider industry change by creating a multi-layered, inclusive, educational and open-ended initiative. “Formalizing a campaign around Earth Day and institutionalizing it will go a long way to get breweries who aren’t thinking about their impact to start to care,” he says. This is also the goal for Tulsa OK’s Heirloom Rustic Ales, which is partnering with the Conservation Coalition of Oklahoma. “Our hope for this project is that other brewers (and growers) will see that consumers appreciate, and even gravitate towards, agriculturally holistic products,” says co-owner and brewer Jake Miller. 

For Steen, the key goal is to raise awareness about brewing and drinking intentionally. “If you’re not already intentional in the way that you source your ingredients, consider making one beer a year where you change things up. And each time you make this beer, get a little more intentional about it,” he says. His advice to consumers? “Ask breweries what they’re doing to support producers and suppliers who are environmental stewards, and go out of your way to support breweries that are intentional.”

Earth to Beer releases will be available around the country this April. Find the full list of participating breweries here.

Singer’s respect for soil inspired her to found Carbon Sponge, an interdisciplinary platform that honors this threatened resource by cultivating healthy soil to foster carbon sequestration. “Carbon sponge” is a term usually used to describe healthy soil that absorbs and retains water; Singer found it aptly described the subject and actions she wants to cultivate. 

Fighting climate change

Greenhouse gas emissions, which result from high levels of atmospheric carbon, are a critical cause of climate change. That systemic shift is responsible for weather patterns, such as periods of intense drought or rain, imperiling all aspects of life, particularly our food supply. Yet agriculture in the United States is responsible for about 10 percent of the country’s emissions and food production accounts for more than a quarter of global emissions, when factoring in the larger food system, including packaging and transportation. 

Carbon storage is an important tool in combating climate issues because sequestered carbon produces fewer emissions. It also improves soil’s fertility, its structure for conveying nutrients and capacity to retain water. Healthy soil is more productive and leads to better growing and farming outcomes.

Singer hopes to fight climate challenges and generate a societal shift in which decisions about land use practices, such as fracking, are thoughtfully made to support humans and other species that rely upon the ecosystem. Carbon Sponge, she says, is “part of our nature-based solution[s] to our man-made problems.”

Anybody who is interested—urban, suburban or rural gardeners and farmers or any land stewards—can participate in Carbon Sponge. Singer has written a manual, “Carbon Sponge Guide: A Guide to Grow Carbon in Urban Soils (and Beyond),” available on the Carbon Sponge website. It explains how to assemble a toolkit of inexpensive, easy-to-purchase-and-use instruments to test metrics such as the fungal to bacterial ratio, which indicates soil’s ability to provide hospitable conditions for carbon storage. Chapters discuss how to monitor and teach children about soil and to design a carbon sponge. An educator at heart, Singer wants to offer tools to teach people to develop new ways of thinking.

Putting soil first

Centering soil in conversations is at the heart of Carbon Sponge. “First of all, asking, what does soil need? Which I think is an interesting question unto itself,” says Singer. “Then also, ‘what can we learn from soil?’” 

Farming methods over the past 50 years, such as growing monocultures and fertilizing depleted soil to prop up the system, are shortsighted, says Singer. She wants to invest in rather than impose on or extract from soil. “If you’re just looking at a yield and how much you get on the land, then you’re not understanding the complex systems that support the growth of that plant and future growth,” she says. 

Singer is notably not a scientist. She’s an award-winning professor of New Media at SUNY Purchase where she teaches Dark Ecology, a class closely aligned with her work in the ecological art space. It explores what it means to be human in the age of the Anthropocene, reading theorists, she says, who straddle art and science and think about how those disciplines can help people interrogate and rethink humans in relation to soil, microbes and the food we’re growing. Singer’s work, at the intersection of technology, art and social change, has been exhibited at MoMA/PS1 and is in the collections of the Whitney Museum of American Art.

After participating in collaborative art projects involving food waste, Singer wanted to learn more about soil. She also wanted to transform that waste into a rich resource. Those interests led her to co-found La Casita Verde, a community garden in South Williamsburg, Brooklyn. 

Singer had worked a lot with data collection, visualizing data in her art practice and generating data in various projects. Learning that the soil had to be tested for lead, a common contaminant in urban soil, prompted her to wonder what it was not being tested for and what would be useful to the soil. “What other kinds of data could we collect in the garden,” says Singer, “that kind of filled out the story about soil?” 

Group effort

Carbon Sponge, formed to explore regenerative agriculture in urban gardening, incorporates art, scientific research, data collection and agriculture. For its initial project in 2018, Singer, as designer in residence at the New York Hall of Science, assembled soil scientists, artists, agroecologists, urban gardeners, landscape designers, government agencies and corporate funders. The goal: to find out how carbon cycles in urban soils and if it was possible to grow soil organic carbon in urban soils in the same way that happens in native rural soils. “I was very interested in making an aesthetic and pleasing experiment so that people would be pulled in by it and want to be in this space and start to learn and ask questions with us,” says Singer. 

Urban soil is very different from rural soil, which is much less disturbed by humans. So, the experiment combined “technosol,” also known as human-engineered soil, a mix of sediment and compost, in different ratios. It demonstrated that soil organic carbon could be developed in urban soil.

The findings are important because the sediment, previously considered waste, can now be considered a resource, opening up new potential for use in ecosystem services and regenerative agriculture. A paper detailing results is currently under peer review. 

Singer’s integrative, collaborative approach and activist streak are influenced by her time at Carnegie Mellon University, where she earned her MFA. There she co-founded Preemptive Media, a collective of artists, computer scientists and roboticists who explored the then-new field of human and computer interaction. She enjoyed being part of a group that “included people who knew how to build projects both in the physical and technological sense and create projects that were bigger than one person,” she says, “and often with an eye towards inclusion, participation, transparency and building a better world with more of a democratic input.”

Carbon Sponge now also encompasses scientific research, Singer’s art practice, a farmer-to-farmer network called Carbon Sponge Hub (located since 2022 at White Feather Farm in Saugerties, New York, where Singer is the director of Farm Innovation), and a yearly soil fest there.

Last year, 10 small area farms participated in the Hub, which includes professional lab testing to substantiate kit results. Planning for 2024 is underway, with intentions to scale up production from a hand-harvested-and-winnowed operation to a machine-driven one, to formally verify the kit, thanks to a USDA grant, and to explore culinary uses.

The Hub is also growing sorghum alone and in cover crop mixes for a scientific study to determine if sorghum can be called a “New York climate-smart plant.” The nutritious grain from Africa possesses numerous agronomic and sustainable properties that can help soil store carbon. It is drought resistant and produces a significant amount of plant biomass, which can be used by farmers to nurture the land. Notably, it efficiently photosynthesizes more “exudates” (“basically, liquid carbon,” explains Singer) into the soil through its vast root system, which helps microbes multiply, building soil health. Hub farm Zena Farmstead reported a 50-percent increase in microbial biomass in its experimental plot from its first to second year of participation. 

Looking ahead

Current generations may not see the benefits of this work; carbon sequestration can take many decades. But Singer is undeterred. “This provides one model,” she says. “We have to be on soil time, which is very different than human time. Both should be part of the solution.” 

Carbon Sponge is modeling new ways of thinking that are necessary for human survival. “We can’t get ourselves out of this problem in the same way we got into it, with extractive capitalists and profit-driven systems,” says Singer. “I’d like to think of this as a different way forward.”

The history of the United States is a history lined with apple trees. Early European settlers in America brought with them apple seeds, which they planted to begin the first orchards. Apples were a fruit of survival at the time, storing well and serving as both food and, in the form of cider, drink.

After the Revolutionary War, apples proliferated across the frontier. The legend of Johnny Appleseed is the story of a real man, John Chapman, who planted apple seedlings across what is now Appalachia and north into Ontario, Canada. Most homesteads up and down and across the expanding United States had several apple trees, if not full orchards. They were planted for food, to produce new trees to sell and for the production of hard cider, which was one of the most common drinks consumed in colonial America. 

By the 1900s, apples had fallen out of favor. The introduction of prohibition eliminated the market for hard cider, and as railroads transformed transportation across the country, the market changed. Now, a few large apple orchards, growing only one or two varieties of apples, control the apple market. Today, 22 percent of apples sold in US grocery stores are the variety Gala, and most supermarkets offer only a few varieties. The backyard apple tree was left to grow wild—until a recent surge in interest in heritage varieties and hard cider production.

As scraggly and unkempt as an old apple tree may appear, it can still be a stellar start to an orchard or a fruitful addition to a family homestead. 

“Planting new trees is going to take some years before they’re mature and fruit bearing,” says Jennifer Ries, who coordinates the tree nursery department at Fedco, a tree and seed cooperative out of Clinton, Maine. “With these old trees, we have gifts from anonymous strangers of the past who planted these trees for particular reasons.”

Old tree discovery and restoration was once the purview of dedicated pomologists such as John Bunker, author of Not Far From the Tree, and Dan Bussey, author of The Illustrated History of Apples in the United States and Canada. Bunker would travel the backroads of Maine and knock on the doors of old farmhouses with peeling paint and sagging roofs. He would scout the property for aging apple trees and, if he found them, collect fruit and cuttings. He has worked to identify more than 500 cultivars in his ongoing career.

But today, it is more than just a few of the apple-obsessed who are discovering and rehabilitating old trees. The surging popularity of hard cider has inspired farmers to revitalize old orchards and plant new ones, and even single backyard trees are benefiting from the renewal.

“We get a lot of emails from cider makers,” says Amy Dunbar-Wallis, a graduate student at the University of Boulder in Colorado and community outreach coordinator for the Boulder Apple Tree Project. “And we hear from homeowners who have apple trees on their land and want to be cider makers.”

Organizations such as the Boulder Apple Tree and nearby Montezuma Orchard Restoration Project, as well as the Maine Heritage Orchard in Maine, the Lost Apple Project in Washington and the Temperate Orchard Conservancy in Oregon, have grown in the past decade to support curious homeowners and passionate arborists alike.

If you have a homestead with an ancient apple tree in the backyard or perhaps a small orchard full of leaning, bending and twisting trees, it is possible to reclaim the productivity of those trees. According to Ries, apple trees can produce bountiful crops for 200 years, so some of those homestead trees may just be getting started.

Identify the tree

You can restore an aging apple tree and appreciate its fruits without ever discovering what variety it is, but testing a tree to discover its lineage will help you understand its unique qualities and may help apple historians in their quest for “new old” varieties. Identification can help connect you through time with the farmers who originally planted the tree by understanding if they used the fruit for cider or cold storage or ate it fresh.

“There are thousands and thousands of cultivars in the US,” says Dunbar-Wallis. Some cultivars can be identified by comparing fruit to old records and old paintings, but there are more high-tech options available now. “We are able to take just a few leaves when they first emerge, fresh in the spring. We send them off to Washington State, where they are able to do some DNA analysis of those leaves and compare them to datasets in Europe. That allows us to figure out not only what the tree is but who its parents and grandparents are and figure out where all of these different cultivars fit into the overall pedigree of apples.”

You may discover you have any number of common homestead apple varieties or you may have something truly rare on your land. Jude and Addie Schuenemeyer of the Montezuma Orchard Restoration Project have discovered varieties of apples where only one single tree of that cultivar remains. Among them was the Colorado Orange, a fruit that was part of state lore for its unique color, flavor and late ripening. 

First pruning

Most trees discovered on old homesteads require an initial pruning to remove dead growth and allow the tree unencumbered sunlight. The first steps in rehabilitating a tree include removing any brush or brambles that are overcrowding it and cutting out any larger limbs that have died or show signs of disease.

“The best thing you can do for old trees is some dead wood pruning,” says Laura Seeker, who works on old apple tree restoration for Fedco and the Maine Organic Farmers and Gardeners Association. “Get out anything that’s dead, decaying, diseased and damaged. Do any clearing out you can in the canopy so that the tree just has live growth.”

Annual pruning

After initial canopy clearing and deadwood removal, the key to a happy apple tree is annual pruning. This encourages the tree to focus its energy on fruit production by removing some of its new growth, and it also allows it to get the maximum energy possible from the sun by keeping it from shading itself out.

“Once we’ve got the canopy cleared up, that opens up the tree’s photosynthesizing,” says Mike Biltonen of Know Your Roots LLC, which specializes in the holistic restoration of old orchards. “At that point, we want to keep it on a maintenance schedule, pruning every year or every other year and addressing any serious issues. We don’t want to do anything to shock it in those first few years, and we don’t want it to lose its wild or feral nature or its uniqueness of being an abandoned or lost tree.”

Annual pruning to keep the tree in top shape usually takes place in late February or early March, when the first signs of early buds begin to appear. 

“Apples really like to be pruned,” says Dunbar-Wallis, “So, during the dormant months, you are going to want to snip the new growth. The new growth is going to grow at a 90-degree angle to the original branch, and you want to snip new growth.”

Tree cloning

When you are pruning your tree, you can begin to start a new orchard from the old variety by taking clones from the tree. Apple tree clones are created by taking a pruned “sucker” or new year’s stem of growth from the original tree and grafting it to rootstock. Rootstock is apple grown from seed, and it is available from most tree nurseries.

“It’s very endearing,” says Seeker, “because, sometimes, there’s a young, young tree of the same variety planted next to an old tree. That old tree is not going to live forever. But having a little replacement there that’s grafted from the same tree is a really nice gesture to leave for whoever inhabits this land. We have these varieties because generation after generation was here grafting, selecting for what works for this climate and what works for our palates. And so, we get to continue doing that, selecting which varieties are still working for us and planting those out and leaving them as something for future generations.”

Trees from seeds

Apple trees do grow from seed, but as a heterozygous species, their seeds do not produce the same variety of apple as the tree from which they came. When you first start rehabilitating a tree, you can look for a graft line to understand if it was selected and planted by arborists of the past or if it might have been grown from seed. Johnny “Appleseed” Chapman famously only grew apples from seed in spite of their unpredictability, but most seedling trees are the remnants of a meal consumed by a coyote or a deer.

“Even on very old trees,” says Ries, “sometimes, you can still see signs [of a graft line] by the way the bark is there—there might be a bulge or there might be a change in the bark direction.”

But if your tree is a seedling, that does not mean its fruit cannot produce something delicious. Some believe that Appleseed planted from seed because he was growing for hard cider production, and the flavors of “wild” apples can be particularly unique for cider pressing. 

“Feral or wild varieties have quite a bit of bioregional resilience,” says Biltonen. “They may have more resilience to their current location and to the climate issues we are dealing with.”

When challenging its pork producer about its use of manure lagoons and the myriad health and environmental issues they pose, Ganzler knew that Bon Appétit’s end goal was not only to source more sustainable pork but to be able to communicate effectively with its customers about the issue—something that is quite difficult, since no one wants to talk about manure when they’re eating.

This tension is at the heart of Ganzler’s new book: How can companies practice authentic sustainability and work it effectively into their marketing strategy? In the book, Ganzler details Bon Appétit’s progress and missteps in navigating issues such as farmworker rights, pigs raised in gestation crates, chickens in cages, and more. The book, which comes out April 2, also includes interviews with other industry experts who talk about their experiences, including:  Rob Michalak, former global director of social mission for Ben & Jerry’s, who talks about integrating sustainability into operations and his experience with Milk with Dignity organizers; Gary Hirshberg, co-founder of Stonyfield Organic, who discusses picking your battles and taking stands on issues; and Lisa Dyson, CEO and co-founder of Air Protein, who talks about creating alternative protein and striving to be the number one meat company in the world.

This interview has been edited for length and clarity.

Modern Farmer: In your book, you say that when a business does something right or makes progress toward a sustainability target, it should get credit for it. This can bolster the business, but you write that it can also create a ripple effect toward industry change. How so?

Maisie Ganzler: A great example of that was in 2005, when we at Bon Appétit made a commitment to cage-free eggs nationwide. We heard that the client at another corporation said to their food service provider, ‘We’d like cage-free eggs served here,’ and the food service provider said ‘Oh, we can’t do that. There’s not enough available, blah, blah, blah,’—all these excuses. And the client said, ‘Well, Bon Appétit does it for their locations. So, I’m sure you can do it here, too.’ That’s the ripple effect that I’m talking about—once a company has proven that something is possible, other companies now need to come to the table and do the same.

MF: Something you worked on passionately was sourcing pork from producers that don’t house pigs in gestational crates. You didn’t reach this goal overnight but through a series of milestones. You eventually accomplished this with pork producer Clemens Food Group, on which Modern Farmer reported here. To get there, you first had to hear big companies tell you no, it wasn’t possible. Why did you push on regardless? How were you confident you could achieve something that wasn’t being widely done at such a large scale?

MG: I pushed on for two main reasons. One was that it was simply the right thing to do. If you’ve seen a sow in a gestation crate, it’s heartbreaking. They can’t turn around, they can’t walk; it is very clear that something better could be done for that animal. So, that’s where we start, rooted in the idea that it’s the right thing to do for the animal. But as you’ve pointed out, we’re also a business and we want to get market credit. And we had made a public promise, and I was not going to go back on that. So, while I was transparent about the difficulties and about missing the deadline, I never wanted to say it can’t be done. Was I confident that it could be done? Not necessarily, but I don’t need confidence to keep pushing forward.

MF: You advise companies to own their challenges and obstacles to achieving their sustainability goals—something that can be tempting to hide. Why is it actually better to be transparent about these things?

MG: Being transparent is important because one, it will insulate you to some degree from greenwashing claims. If you are the person that’s stepping forward and saying here’s where we fell short, nobody can have that “gotcha” moment. The other thing is that it actually gets you more credit in the end. If you pretend that everything’s easy to do, why should anybody celebrate that you did it? If you’re transparent about how challenging it was, how many bumps there were in the road, how many times you failed and redoubled your efforts, how much more expensive it was, then all the more reason for customers or advocacy groups to laud your accomplishment when you finally do pull it off.

I don’t think that anybody on the consumer side, anybody reasonable, expects perfection from a company. But they do expect honesty. And I think that’s a reasonable expectation. One of the things that I talked to Gary Hirshberg about, the founder of Stonyfield, is he talked about people needing to make an emotional connection with the brand, especially if you’re asking them to spend more money on something. Just what I was talking about [with] gestation crates, and how they are so horrible for sows, that cuts to my heart, not necessarily to my head, because it is more efficient, it is more cost-effective, but my heart tells me something different. And a lot about building an authentic brand based upon sustainability is listening to your heart and being open with your heart.

If you’re not authentic in your desire to make real change, I think that people smell that. And you may actually have something backfire. Instead of [achieving] what you want, you may be in a worse position if you’re inauthentically making these promises.

MF:  You talk about how in Bon Appétit’s Farm to Fork program, you don’t require that producers be certified organic, but you do require that farms be owner-operated. As a farmer in St. Louis told you, if you’re a small farm, you can’t afford to scrap a whole field if you have a fungal outbreak, you need to be able to apply a fungicide. If you held firm to requiring organic certification, you’d end up putting the squeeze on some of your smaller producers. When setting a sustainability goal, how do you make sure that the parameters you choose can actually help you achieve your desired outcome?

MG: You have to first be really clear of what your desired outcome is. So, for the Bon Appétit Farm to Fork program, the desired outcome was to support farmers that were growing for taste—that was the initial impetus of the program: to get the best-tasting food. And to do that, we decided that we had to support small-scale farmers that were close to us that were able to grow for flavor, as opposed to grow for conformity or transportability or a whole host of other reasons. Be really clear about what your goal is. 

MF: Considering Bon Appétit’s size and reach, you encounter a lot of issues in our food system. You work with producers across a wide geography and advocates on a wide breadth of issues. From your perspective, what are the biggest issues in our food system right now? 

MG: From sitting in the chair of a food service company that’s a buyer, I think that the biggest issues really surround animal agriculture, how animals are treated and the impacts that the raising of those animals have on our environment. And there’s a lot of different things in play. And there’s a lot of strong opinions but also some conflicting information. So, I would say that there’s a whole host of issues around animal agriculture.

MF: For small farmers or food businesses that don’t have a marketing department, budget or training, do you have any advice for how they can still tell their story effectively?

MG: I think that the first thing is that they need to figure out what their story is and distill it down. If they have a package, what can they put on the package that quickly communicates the most salient points of their story, not the encyclopedic version of it, because no one’s going to take time to read that. Everybody’s got a website, so the same thing there, really figuring out what your headline is and succinctly communicating that to your customers. And making that headline something that does create an emotional connection with people. Not being afraid to take a stand, whether that is in the issues you take on, how you talk about them or where you talk about them. 

What I was trying to communicate in the book is the importance of both making meaningful change and getting market credit for it. And that’s where the title comes from—You Can’t Market Manure at Lunchtime. There was this real environmental change we were after, dealing with manure lagoons, but we also needed to be able to talk to customers about it. Because we are not advocacy groups, we are for-profit companies. But we have the power to do good in this world and capitalize on it. And there’s nothing shameful about that duality.

I raise and sell several hundred vegetable, flower and herb starts every spring, which meant that I was constantly purchasing plastic pots. In my experience, even high-quality plastic pots tended to fall apart after a few years, and I knew many people who simply threw them away after a single season of use. The idea of eliminating this form of waste was appealing to me, as was the additional promise of raising healthier plants in the process.

What is soil blocking?

Soil blocking is the practice of utilizing compacted blocks of soil to germinate and grow out seedlings before transplanting them into the garden. Soil blocks act as both the container and the growing medium, relying on a metal tool called a soil blocker to create the compressed cubes. 

Although the concept of soil blocking has been around for quite some time, its popularity has been steadily gaining traction, touted by many regenerative-minded farmers and adventurous home gardeners as a way to decrease plastic waste and the resulting impacts to the environment. “Soil blocks are the answer for a farm-produced seedling system that costs no more than the soil of which it is composed,” writes Eliot Coleman, a vanguard of the modern soil-blocking movement, in his seminal book, The New Organic Grower. “Blocks free the grower from the mountains of plastic [trash] that have become so ubiquitous of late in horticultural operations.” 

Soil blocking is also gaining in popularity because it promotes a healthier root system by utilizing a process known as “air pruning.” Due to the freestanding nature of each soil block, the plant roots are exposed to oxygen on all sides. The result is that, as the plant roots hit the outside edge of the soil block, they are effectively “burned” off via exposure to air, causing the plant to consistently produce new branching roots and thereby creating an overall healthy root system. 

When it comes time to move seedlings into the garden, soil blocking also allows for a gentler method of planting, thereby reducing transplant shock. Even plants that normally don’t like having their roots disturbed, such as cabbage, can be grown and transplanted successfully using soil blocks.

Daniel Mays, founder of Frith Farm and another early adopter of the practice, believes that soil blocking also allows for the creation of a larger rhizosphere, (which is defined as the zone of soil where complex symbiotic interactions take place between the plant’s roots and beneficial microbes and fungi), because each block holds more soil than the tapered cells of plastic plug trays. “This means more roots, more soil contact and a more resilient plant.”

The opposite holds true for a plant raised in a traditional plastic pot: The plant’s roots become restricted and, having nowhere to go, head downward to the bottom of the pot, eventually resulting in what feels like an infinite swirl of frustration. When this happens, it is called becoming “rootbound” and this condition can not only stunt the plant but (in extreme cases) potentially even kill it. After being put in the ground, a rootbound plant can remain stunted, unable to overcome its constricted root system. It may take much longer to establish and, in the case of garden vegetables, produce a lower overall yield.

Now that we’ve covered many of the reasons in favor of soil blocking, what about the drawbacks? To be fair, soil blocking does involve a bit of an upfront commitment in the form of the costs associated to purchase the necessary tools, as well as a bit of extra labor involved to make the soil blocks themselves. I believe that these small obstacles are still vastly outweighed by the benefits that the overall system provides (not least of which, for my farm, included increased sales by offering a unique product).

How to soil block

 So, you’ve decided to try your hand at soil blocking—now what? The first thing you need to get started is one or more sizes of soil blockers, which are essentially an ejection-style press that compacts the soil into squares. You can choose from either smaller handheld versions (good for home gardeners and more economical in pricing) or larger (and more expensive) stand-up style ones. Most blockers come in several sizes, allowing you to keep sizing up your soil blocks as the seedlings grow and require more space.  

On my farm, I use three different sizes of handheld soil blockers. To germinate small seeds, I usually begin with a 20-square press (3/4-inch-diameter block size). When dealing with larger seeds such as okra, it’s best to skip this press size and germinate them directly into two-inch-diameter blocks. The one issue to keep in mind with the smaller block size is that the soil can dry out faster than with the larger blocks, so care and attention is needed so as not to accidentally lose fragile seedlings. 

At the onset of the seedlings’ first true leaves, I move them into two-inch-diameter blocks made using the four-square press. As the seedlings become more mature, I move them up to the final four-inch-diameter block size, using the one-square press, a couple of weeks prior to transplanting them into the garden. 

Part of what holds the soil block together is the established root system of the plant. It generally takes a couple of weeks for each seedling’s roots to fill out the soil block, so I highly recommend waiting for that amount of time before moving a seedling up in block size. I also recommend waiting until the seedlings have established roots in their soil blocks before attempting to transport them to market.

There are as many different formulas for ideal soil-blocking mixtures as there are farmers using the method. Each person has their own idea of what works, and everyone thinks that their recipe is the best. At the end of the day, the important part is that your soil mix is compactable but still possesses good drainage, which is why many folks recommend a blend that includes finely sifted compost (or potting soil) and coconut coir. I recommend experimenting to see what works for you and coming up with your own special blend. It can be something as simple as off-the-shelf seed starter soil or as bespoke as a mix of fine-grained homemade compost and sand with a small amendment of pulverized egg shells (such as that used by Siskiyou Farm). 

I also recommend using a deep rectangular tray (or even a wheelbarrow) in which to mix your soil medium. The secret to soil blocking is achieving the right consistency: If it’s too dry, it’s prone to crumble and fall apart; if it’s too wet, the blocks will slump over and deform. To make the mixture stick together and compact well in the blocker, you need to add a lot more water than you would think. According to Coleman, the ideal consistency is “much moister than most growers are used to. We are talking about something akin to chocolate fudge mix.” Essentially, it needs to be moist enough that, when you squeeze a handful of the soil mixture, a little water comes out.  

After you have filled all the squares in the blocker with soil mixture and smoothed off any excess, press firmly until you see water seeping out of the bottom. Then, release the handle and gently lift the blocker away (I recommend also using a slight rocking motion as you lift up), thereby freeing the soil block squares. Don’t feel bad if your first few attempts end in tragedy (mine certainly did!); perfecting this technique can take a little practice.

Beyond decreasing my reliance on plastic, soil blocking has had the added benefit of increasing my plant sales. By being one of the first farms to implement it on a commercial scale in my area, I can offer a unique product that really piques customers’ interest. Displaying shelf after shelf of soil-blocked plants in my farmers market booth is an excellent recipe for attracting curious passersby who want to know more about the pot-less plants. I have noticed a marked uptick in foot traffic and revenue at my booth by offering my plants in soil-blocked as opposed to potted form. 

While soil blocking does require a bit more labor and an upfront investment in tools, its benefits far outweigh these minor obstacles. Eliminating the need for plastic pots, creating healthier plants and root systems and—if you’re selling plant starts— increasing sales, are all reasons to give soil blocking a try.

In a landfill, food and organic materials are dumped into the landfill, with more waste continually piled on top, creating compacted, oxygen-deprived areas where bacteria flourishes to break down the organic matter. The decomposition process generates methane, a greenhouse gas. According to the EPA, “municipal solid waste landfills are the third largest source of human-related methane emissions in the US.” 

Put another way: The majority of things we casually toss into the trash can be composted, with big benefits for the planet. 

Composting is a pretty basic concept, although there are several ways to go about it. Essentially, composting speeds up the decomposition process by adding organic matter to an oxygen-rich environment and then letting the bugs and fungi that break down matter do their thing. There are small, backyard-scale composting setups with worms (known as vermicomposting), large, industrial-sized bins that rotate the matter consistently to ensure the right airflow and all sizes in between. Whatever method you use, eventually, the end result is compost—a nutrient-rich soil that can be used as a soil amendment. 

Roughly 15 million American households have access to a food-waste compost program, with about 400 programs spread across 25 states. That’s about 12 percent of households across the country. If composting is a big win for cities—taking waste out of landfills, producing fertilizer and engaging citizens in the recycling process—why doesn’t everyone do it? Well, like most public works initiatives, it’s not that simple.

‘One size doesn’t fit all’

So, what does it take to implement a new composting program? In 2017, Washington, DC’s Department of Public Works put together a survey to assess the feasibility of a compost program for local residents. There are a lot of considerations; in this case, it found that the main obstacle was processing capacity. For a city of about 700,000 people, where does all of that waste actually go? 

The city just did not have the space to divert waste from the landfill at that time. However, in the intervening years, industrial composting programs in DC-adjacent Prince George’s County have increased, and other cities such as Boston have started composting—a development that Rachel Manning, a program analyst within Washington’s Department of Public Works, and her team have watched with interest. Finally, in August of 2023, seven years after its initial study, Washington launched its pilot compost program. 

The city now has about 10,000 households participating in the pilot program, with regular curbside pickup of compost, along with trash and recycling. Manning says the team sends out regular surveys to participants to see how things are going throughout the program, which is scheduled to last for a year. “Something that’s interesting to us is understanding that one size doesn’t fit all,” Manning says of the issues that have popped up from resident responses. “Maybe not everyone fills up a five-gallon bin, maybe some people want more than five gallons…so there’s a little bit of thinking about what are the right sizes of these containers? What type of [truck] fleets do we need to serve all these homes? Right now, it’s not the same size as our trash packer trucks, because we’re not servicing as many people. But also, food has a lot of moisture in it, so you need a particular vehicle for that. Also, [the Department of Public Works] has a goal to electrify all of their fleet. So, we need to think about electric vehicles, and what the capacity is there.” 

So far, Manning says the program has been a success. It has about a 70-percent adoption rate among participants and has diverted more than 400 tons of waste from the landfill. The city also brings the compost back to residents (if they ask for it) to use in their gardens, so there’s even more incentive for residents to compost. This summer, when the program is scheduled to come to an end, Manning and the team will evaluate moving forward with composting on an even larger scale.

‘We’re willing to pivot’

“I’m going to tell you a secret,” says Melissa Kozakiewicz, assistant city engineer in Kansas City, Missouri. “I always start with pilots, and using the word ‘pilot,’ I can pivot and be flexible when things are working and when they’re not….but we aren’t going to take it away.” 

Kozakiewicz, who has previously built up a compost program in Jersey City, New Jersey, is now spearheading the compost pilot program in Kansas City. She’s hoping to replicate some of her previous successes, particularly in how she makes the program available to residents. “You have to be really deliberate and careful with how you introduce [a compost program]. You don’t want anybody to feel like you’re jamming something down their throat, because then they’re out,” says Kozakiewicz. Instead, she works at a pace with which the community is comfortable and integrates demonstrations at big public events, such as a Fourth of July parade. That way, residents get comfortable with composting as part of their public life and might be more inclined to continue doing it at home. 

[RELATED: Map: Who Composts?]

Kansas City also doesn’t currently offer a curbside pickup of compost. Instead, its model is a drop-off program. The city has five current drop-off locations, with 10 more to come around the city this year. Kozakiewicz says that helps prevent contamination of waste, because compost bins aren’t lying around next to trash or recycling containers. If residents make a trip to a special, designated location, it helps to reinforce what that location is for. It also helps ward against another common concern for cities: vermin and pests. “We have one of our drop-off spots inside of City Hall’s garage. It’s a publicly accessible space that anybody can use,” says Kozakiewicz, and the regular foot traffic allows for a lot of feedback if something’s amiss. “If you call me and say ‘Hey, I was at the City Hall garage, and it looks terrible,’ I can call somebody right this minute to go check it out.” (Data on adoption rates for composting are harder to find, but studies suggest that in the case of recycling programs, residents are more likely to participate when the programs offer curbside pickup.)

Both Kansas City and Washington, DC, are experimenting with programs at the municipal level and with just a portion of their residents so far. But can these programs scale up? Recent state-wide legislation is trying to answer that question. 

In Vermont, a state-wide food scrap ban went into effect in 2020. Residents separate their food scraps and either compost them in their own homes, drop them off at a designated station or sign up for curb-side pick-up. The law also prioritizes reducing food waste upstream, ensuring more food goes to food banks or is turned into animal feed. At the time of implementation, Josh Kelly, materials management section chief at the state’s department of environmental conservation, told Vermont Public that state legislators had been working on reducing waste since 2012. “We have had a state goal to have 50 percent of the waste that we produce separated and recycled, reused or composted. And that goal has never been met in all the years that it’s been in place.” In the year following the ban’s implementation, sales of backyard composters in Vermont more than doubled, and a survey last year found that 61 percent of Vermont residents felt a “moral obligation” to keep food out of landfills (although the state is still not meeting that 50-percent goal).

California is hoping to see some of that success, after it implemented state-wide legislation in January of 2022. The goal of the law, says Lance Klug, with CalRecycle’s office of public affairs, is to reduce the amount of organic waste in landfills by 75 percent and reroute 20 percent of fresh, unsold food to Californians in need, both by 2025. The law requires all cities and counties in the state to implement programs to collect organic waste and increase food recovery from sites such as grocery stores. So far, says Klug, the program is chugging along, although it’s run into issues ranging from COVID-related supply chain slowdowns to a slower adoption rate than hoped for. Roughly 75 percent of jurisdictions in California now have a composting program in place, and in 2022, about 200,000 tons of unsold food was recovered and redistributed to folks who needed it. However, as reported by the Associated Press, it’s unlikely the state will meet its 2025 goals.

‘Education can’t be understated’

Not everyone has a state or even a city supporting them in the effort to compost. But for some folks, that doesn’t matter—they just do it anyway. 

For Bob Ferretti, that was no small feat. He’s the associate director of administrative services at Yale University, which at any given time has about 25,000 students, staff and faculty on the campus. That’s a lot of waste. 

About 15 years ago, Ferretti and his team began the process of figuring out how to facilitate a composting program on campus—made more difficult by the fact that, at the time, the city of New Haven, Connecticut, where Yale is located, did not have a program in place municipally. (Currently, there’s still no residential program for would-be composters in New Haven. However, the city does mandate that if you are a large business, produce enough compost and are located within 20 miles of a compost facility, then you are required to use it.) “There’s really no composting infrastructure within the state at an industrial scale,” says Ferretti. “There were small organic operations within local farms and things like that, but nothing that could handle the volume we were producing.”

At first, Ferretti recalls, Yale had to hire trucks to cart the compost daily from campus to a facility on the New York State border, which was a few hours round-trip. It wasn’t the best environmental solution, Ferretti says, for an effort aiming to curb greenhouse emissions. “We did meet with the city to try and come up with something even more local,” says Ferretti. “I don’t think there was a ton of real estate available for it.” Plus, says Ferretti, there were questions about who would own that kind of project. Would it be a municipally run program that only serves Yale? A private program for the university but that utilizes local government? Ultimately, Ferretti and his team found an industrial composter within the state, only about 30 minutes from campus, and partnered with it. 

There were some initial wins for the Yale project. As students who lived on campus mostly lived in residence halls and ate at large dining facilities, much of the waste was already centralized, making it less difficult to collect than in a spread-out city. But this was more than a decade ago, and Ferretti says they had needed to do a lot of education to get everyone on board. “We did a lot of waste stream audits for visual awareness, you know, where we dumped out bags of trash across campus and had people in Tyvek suits sorting through and showing people what’s in our waste stream so that they became aware of how much could be diverted,” says Ferretti. “We would have the students actively weigh plates after every meal, to see how much food was scraped into this bucket, so that they know how much was being composted.” There were still challenges with cross contamination, as silverware, latex gloves or other generic trash was easily dropped into the wrong container. “Education can’t be understated,” says Ferretti. 

There’s a lot to consider when starting up a new compost program. Even if your municipality offers curbside trash and recycling collection, adding compost to the mix isn’t as simple as buying a few more trucks and hiring some new workers. But with each new program that gets introduced, there are more examples of how to make composting work for cities, towns and even private entities of any size. 

In Kansas City, Kozakiewicz says the important thing to remember is not to wait for things to be perfect—you’ll be waiting a long time. “You’ve got to kind of push a little, using the resources that you have,” she says. “Nobody’s interested here in building a new landfill.”

On this particular afternoon, Cameron Rentsch is pedaling an e-bike through Missoula’s University District. Hitched to the back of the bike is a narrow trailer, holding three tall receptacles for collecting food scraps. They won’t all get filled today as this route is quick—only eight stops. Rentsch follows a map marked with the addresses and, at each house, picks up a small white bucket filled with organic waste—apple cores, coffee grounds, wilted roses—and dumps the bucket into one of the receptacles on the back of the trailer. 

Rentsch does this work for Soil Cycle, a compost-based nonprofit. Monday through Friday, Soil Cycle sends its cyclists out on the road, picking up food scraps from houses and businesses and taking them back to its facility. Not only do Soil Cycle’s staff pick up the food scraps, but a few times a year, its customers can pick up the end result: compost for their home gardens. What’s more, they do it all on bicycles, keeping the transportation sustainable. In 2023, Soil Cycle diverted more than 49,680 pounds of food scraps from the landfill. It’s a circular, closed-loop system. 

Meeting a need

When Caitlyn Lewis was in graduate school at the University of Montana, there was no municipal food waste collection system in Missoula. So, after graduation, she decided that’s where she wanted to focus her energy. As a result, she founded Soil Cycle.

“I was sick of throwing my veggies away when I was cooking, and I was adulting a little bit more and cooking with more fresh produce and thinking about my waste stream a little bit more than maybe I did when I was in high school. And there was nowhere to put it.”

Missoula is far from the only city to have a community compost program, but Soil Cycle stands out for its focus on sustainable transportation. There are a handful of other communities that also have bike-powered food scraps collection, such as BK Rot in New York City and Peels & Wheels in New Haven, Connecticut. Soil Cycle has gone through several different mission shifts since its founding, but the bicycle transport has remained one of the core values, says Lewis. 

“We figured we can meet as many issues in our city with one organization…soil health, food waste, carbon sequestration and sustainable transportation,” says Lewis. “It really is an example of how to do business in a different way.”

A few times a year, Soil Cycle is able to give the actual compost back to the customers.

“We’re creating this fertilizer that you can use on your houseplants and in your garden, and they can see firsthand how they’re making a difference,” says Elisabeth Davidson, executive director of Soil Cycle. “And I think that’s probably the biggest part in closing that loop. It’s people seeing the product that’s created by the food waste.”

Even a few years ago, the mindset around composting felt different in Missoula, says Lewis. When she started Soil Cycle, there were about 10 people who signed up right away. But others took some convincing.

“The rest were like, well, why do I need to compost? Why should I pay a service a fee to collect it? Why do you make compost?” says Lewis.

While limiting food waste is best for the environment, redirecting wasted food away from landfills is the next best option. Research from the EPA in 2023 found that 58 percent of landfill-produced methane came from wasted food. Methane is a greenhouse gas that contributes to climate change. Composting integrates oxygen into the equation, minimizing the methane produced when done correctly.

As more municipalities have created food scrap pick-ups and compost services, the directionality is often one-way. People let their food scraps be collected at the curb, says Davidson, and then their involvement ends. She hopes more people will start to wonder where those food scraps end up. 

“I wish folks just knew more about where their food was going after they threw it in the compost bin,” says Davidson. “It gets sent off and then [people are] like, ‘OK, I did my part.’ And that’s true, they did do their part. But looking throughout the system, you need to think down the line of OK, where’s my food waste going after this? How is it being processed? And how is it being distributed?”

Beyond Soil Cycle and Missoula, many cities have programs where you can purchase or get compost for free, making the process more full circle. In Bozeman, Montana, Happy Trash Can Compost collects food scraps and sells the finished compost back to the community. In Los Angeles, LA Compost provides several options for obtaining free compost, through farmers markets, co-ops or community hubs. Even some of the food scraps collected through the municipal program in Portland, Oregon are processed by Recology Organics, which will sell its compost products retail.

What’s next

A little before 4 pm, Rentsch finishes the route and pulls the e-bike to a stop in front of the gate surrounding Soil Cycle’s headquarters. Dropping off the food scraps and cleaning out the receptacles is the only thing left to do today.

“We can’t save every piece of fruit—organic materials are organic and they will decompose,” says Lewis. “But we should honor them and we should make the best-quality fertilizer we can.” 

Meanwhile, Lewis, who in recent years has also started a flower farm called Blue Mountain Flowers, has realized that there are some additional challenges to composting at the farm level—for example, an abundance of organic material can be hard to “turn,” a critical part of composting, if you don’t have heavy equipment. One of her goals for the coming year is to design a composting system that is easy to manage for farmers and is replicable across small farms.

“It’s a passion project of mine to create a composting system that can be replicated for small farmers,” she says. “And there’s ways to do it, without putting [in] a ton of time. You just have to be creative.”

Since Soil Cycle is hyperlocal, there’s no competition with nearby municipalities. A company or initiative doing the same thing in the next town over is a collaborator, not a rival. 

“It doesn’t necessarily have to be bicycle-powered and identical to what we’re doing,” says Davidson. “But I’d say a lot of local communities are interested in creating some sort of composting service.”

And Soil Cycle’s connections stretch far beyond Montana, as more communities try to pick up the idea.

“I have a meeting with someone tomorrow, who I believe is from Ireland, [who says] ‘I want to do what you’re doing, here,’” says Davidson. “OK, let’s talk about it.”
