Increasing the value and volume of compost in California.
Ongoing Programs
Compost Producer Map
The Composting Industry in California worked diligently to include a procurement policy in SB1383, which resulted in Article 12.
Now, Jurisdictions and the Composting Industry have the chance to work together to save water, reduce pollution, lower GHG emissions from landfills, and support more sustainable agriculture through compost application.
This map of STA Certified Compost Participants was developed by USCC to help find quality compost. Zoom in to California to see STA participants in our state.
