Changes to AB 1826 – State Mandatory Composting Law


State Law Requires More Businesses to Compost, January 2019

Under State of California laws AB 341 and AB 1826, certain businesses and institutions are required to recycle and compost. As of January 1, 2019, the State requires more sites to have organics collection service; businesses and institutions that generate 4 or more cubic yards of solid waste per week must have organics collection service.

Materials that must be composted include food waste, green waste, landscape and pruning waste, non-hazardous wood waste, and food-soiled paper.

AB 341 has required recycling at many businesses since July 1, 2012. Materials that must be recycled include bottles, cans, paper, and cardboard.

Additionally, the Mandatory Composting and Recycling law in Alameda County requires businesses to sort their waste into the proper containers.
