California’s jurisdictions have begun reducing organic wastes under a new composting law that takes effect in 2025, changing the landscape of waste management and making compost more accessible to farmers and cities alike.

Senate Bill 1383, passed in 2016 to curtail emissions of methane and other “super pollutants,” requires local governments in California to reduce the amount of green waste (food scraps and yard trimmings) sent to the landfill by 75 percent before 2025.
