Composting is mandatory in California

California State law (SB 1383) requires residents and businesses to keep food and other compostable materials out of landfills to help fight climate change. The State law is implemented in Alameda County under the Organics Reduction and Recycling Ordinance in partnership with the Alameda County environmental health departments, StopWaste, its member agencies and their solid waste service providers.
