Ordinance Overview


When food and plant material break down in a landfill they release methane, a harmful greenhouse gas and leading cause of climate change. To respond to the climate crisis, California passed Senate Bill 1383 to reduce the amount of food scraps and other compostable materials sent to landfills. The law went into effect January 1, 2022 and aims to reduce organic materials going to landfill by 75% by January 1, 2025.

The law also sets targets to recover and donate edible food. That's because much of the food currently thrown away in California is perfectly good to eat and could feed people instead of going to waste or even composting. Setting up systems to make this high-quality food available for people to eat will not only cut greenhouse gas emissions, but also help alleviate food insecurity in our communities. 

State vs. Local Law

In Alameda County, SB 1383 regulations are implemented and enforced under the Organics Reduction & Recycling Ordinance, through a partnership between StopWaste, the cities of Alameda County, their solid waste service providers, and the environmental health departments. You can find the full Ordinance here. For more background about the State law visit CalRecycle's SB 1383 webpage
