SB1383 Mandatory Compost Recycling
Composting Is The Law
California’s SB 1383 requires all residents and businesses to separate food scraps and yard waste into a green compost cart. These statewide regulations aim to reduce landfill waste and cut harmful emissions.
These rules come from the State of California—not Sonoma Garbage Collectors—and local jurisdictions are required to enforce them. Non-compliance may result in fines, and in some cases, the suspension or denial of permits, licenses, or registrations.
Following the composting guidelines helps protect our environment and keeps Sonoma Valley in compliance with state law.

Understanding Composting vs. Recycling
Composting and recycling both play an important role in reducing waste, but they handle different types of materials. Composting is for food scraps and yard waste, which naturally break down into nutrient-rich soil. Recycling is for items like paper, cardboard, plastic bottles, glass, and metal cans that can be processed and turned into new products. Understanding the difference helps keep our waste streams clean and efficient, and supports a more sustainable Sonoma Valley.
