Community Composting

Spring 2023: New Mexico Compost Coalition launches statewide Community Composting Pilot

The New Mexico Compost Coalition is a network of businesses, municipalities, non-profit organizations, researchers and agency representatives seeking to turn food waste into a beneficial resource through partnerships and cooperative approaches. The coalition is facilitated by New Mexico Healthy Soil and welcomes new members. If interested, please contact Isabelle Jenniches.

Problem Statement

Society can achieve many benefits by redirecting organic waste from landfills to compost systems. Composting organic materials mitigates climate change by lowering CO2 and CH4 emissions, reduces strain on landfills, and prevents water contamination from toxic leachate produced by the anaerobic breakdown of organic material. When applied, compost enhances plant growth, reduces stormwater runoff and soil erosion, and improves soil fertility, structure, and H20 retention. 

Despite the multiple benefits that composting brings, the practice is severely underutilized. According to the EPA, just 8.5% of municipal solid waste is composted, even though more than 50% of municipal waste in the U.S is compostable: 23% paper and cardboard, 22% food, and 12% yard trimmings. In New Mexico, low population density makes compost collection services economically unfeasible in most parts of the state, and even in the larger cities where these services are available, price barriers exclude low-income households. At the same time, home composting is obstructed by lack of space, concerns about pests and wildlife, and need for education about how to compost.

Proposed Solution

To make composting more accessible, the New Mexico Compost Coalition aims to fill the “missing middle” between home composting and municipal composting by establishing a replicable approach to arid-land community composting. In community composting systems, people don’t have to compost at their homes or pay for city-wide service, but instead drop food scraps off at managed sites in their own neighborhoods.

Cities including Washington, D.C. and Lancaster, PA, have rolled out community compost initiatives with great success. Community composting has not yet been tried in New Mexico, which is why we seek to model it through organizational partnerships with strong management, education, and advocacy capacities. Seven members of the New Mexico Compost Coalition have volunteered to host community composting bins locations across the state.

By the end of the project, building on the successes of the seven pilot sites throughout New Mexico, we intend to offer a viable, proven model for community composting that we can help existing and future partners replicate throughout the state, transforming the harms of the existing food waste management systems into environmental, social, health, and economic benefits.

Seven community composting bins, each serving up to 75 households, are being hosted at community gardens and educational centers across the state. Each of the host sites engages communities through brief training sessions to show how the composting program works. Upon completion of the training, individuals can join the site’s compost cooperative free of charge. During regular workshops participants manage the bins under guidance of a local compost captain, process and apply finished compost and socialize. Each site self-determines whether to use the produced compost on-site, distribute the compost among participants—or even sell it for revenue.

Record-keeping and data collection at each site aims to quantify landfill diversion, greenhouse gas emissions reductions and carbon sequestration benefits.

The Community Composting Pilot project is made possible through the NM Department of the Environment’s Recycling and Illegal Dumping Fund.

The 25 acre Agri-Nature Center was created on the site of a former winery to preserve open space and maintain the Village of Los Rancho’s agricultural heritage through education, research, economic development, and community events. The Agri-Nature Center provides agricultural education for farmers and gardeners of all skill levels and ages and demonstrates best practices in regenerative agriculture.

The community compost bin will be placed in the new community garden area.

Barelas Senior Center is home to a community garden and adjacent to a community center, community park, and recreation area. The senior center’s community garden is supported by staff and over 20 volunteers. The community garden is also home to intergenerational programming where students get the chance to learn about nature, gardening, and the importance of healthy soils.

The neighborhood surrounding the Barelas Senior Center site is an economically disadvantaged, underserved area with a SVI score of 0.82, indicating high vulnerability. The Social Vulnerability Index (SVI) score uses U.S. Census data to assess the overall social health of an area according to 15 social factors, including poverty, lack of vehicle access, and crowded housing. A SVI score of 1.0 indicates the highest social vulnerability.

To participate, please call or stop by the senior center. Barelas Senior Center: 505-764-6436

North Valley Senior Center is home to a new community garden that is already supported by about 20 volunteers. The senior center is currently developing intergenerational programming to connect community members of all ages and connect the community with nature and opportunities to learn about gardening, composting, and the value of healthy soils.

The neighborhood surrounding the North Valley Senior Center site is an economically disadvantaged, underserved area with a SVI score of 0.78, indicating high vulnerability. The Social Vulnerability Index (SVI) score uses U.S. Census data to assess the overall social health of an area according to 15 social factors, including poverty, lack of vehicle access, and crowded housing. A SVI score of 1.0 indicates the highest social vulnerability.

The Santa Fe Botanical Garden opened in 2013 with the mission to celebrate, cultivate and conserve the rich botanical heritage and biodiversity of our region.  The Garden is open to the public year round and we offer various educational lectures, workshops and conversations about gardening in an arid steppe climate, as well as fun and inspirational public events in the Garden setting.  Youth interns tend and harvest from our orchard fruit trees and vegetable garden, with produce donated to local food banks.

The Garden is on Museum Hill in Santa Fe, in the heart of a lovely residential neighborhood. We will be working with garden volunteers and students to develop a program for composting our own site-generated garden debris and for using that compost to enhance the soils in our Garden, especially in the vegetable garden and in the restoration of our Pinon-Juniper Woodland. Once we’ve developed our protocols around composting our own garden debris we hope to extend our composting program out to the museums across the street as well as to neighborhood residents.

Our community compost bins are hosted by the Santa Fe Master Gardeners and the Santa Fe Compost Action Team (SCAT) at the Santa Fe County fairgrounds. We are committed to raising awareness about the importance of composting, eliminating food waste from our landfills, improving soil health, and building community. 

We are seeking new members to be actively involved in these community bins. After completing an orientation training, members will contribute food scraps and yard waste and take part in managing the compost (minimum 1 hour of volunteer time per month). Be prepared to learn about the benefits of compost, soil health, the soil food web, and growing a more resilient community and garden.

Want to learn more and get involved? Find our page on Facebook at Community Compost Santa Fe or email us at          

Membership is FREE! Anyone in the Santa Fe area is welcome!
