Potential Policy and Community Implications of Equitable Organic Waste, Compost, and Urban Agricultural Systems in the United States

Urban Farm DB summary

Examines equity and safety in urban organic-waste cycling through a case study of waste-to-compost activities and legislation in four US cities. It warns that contaminants such as pesticides, lead, and PFAS and inconsistent regulation can worsen racial inequities in access to urban farmland and safe compost, and recommends justice-oriented policy with multilingual education and proper waste disposal.

BACKGROUND: Urban organic waste diverted from landfills for use as compost feedstock may help mitigate and adapt to the effects of our changing climate. Yet, compost produced from urban food and yard waste is often a source of contaminants harmful to human and environmental health. Efforts by multiple municipalities are increasing residential and commercial food and yard waste collection; however, finished, tested compost is typically unavailable to those contributing the waste and whose gardens would benefit. OBJECTIVES: ) provide recommendations to promote safer compost production from urban organic waste inputs. The engagement of intersectional partners in the creation of equitable policies and contracts that integrate food and waste justice is crucial to this work. METHODS: A 15-y relationship between community, academic, and government partners in Boston, Massachusetts, has increased access to health-promoting community gardens. Historical concerns raised by gardeners resulted in improvement to the quality of compost sourced from municipal organic waste and motivated a case study of Boston and three other cities (Seattle, Washington; San Francisco, California; New York, New York). This case study provides the approaches used to source, collect, process, test, and deliver urban organic waste as compost for UA. It informed recommendations to improve the safety and equity of organic waste-to-compost cycles. DISCUSSION: Strict feedstock regulation and required compost safety testing are essential to produce safe, city-sourced compost. Balancing the needs of landfill diversion with equitable distribution to all contributors, particularly low-income and food-insecure people, will help concentrate UA benefits within marginalized communities. Adoption of a public health lens may help ensure the safety of nutrient-rich compost available for urban growers through legislation at state and local levels, along with explicit industry contracts. https://doi.org/10.1289/EHP12921.
