Jepson Prairie Organics

Facility Information

Jepson Prairie Organics, located east of Vacaville, California is one of the largest food scrap composting operations in the nation. Jepson Prairie Organics processes approximately 100,000 tons of organic material from San Francisco, surrounding Bay Area communities, and several municipalities within Solano County.

Jepson Prairie Organics utilizes two primary types of feedstock in the composting process. Food scraps generated at restaurants, hotels, markets, and coffee shops throughout Northern California and yard trimmings generated in Dixon, Vacaville and Vallejo.The two feedstocks are fed into an industrial sized grinder and mixed to attain a ratio ideal for biological decomposition. The material is then placed onto the Engineered Compost System (ECS), which was developed specifically for the needs and specifications of Jepson Prairie Organics. Material remains on the ECS for a period of 30-45 days of active composting. While on the ECS zones, biocovers are utilized and temperature and oxygen levels are monitored. The material is also watered and turned while on these zones. After this period, the material is screened and placed into windrows for curing. Once fully cured the material is screened again, finished, and ready for sale.

Jepson Prairie Organics’ quality assurance program includes routine nutrient, metal, and pathogen analysis of our compost to ensure a high quality, consistent product that meets the needs and expectations of our customers
