Mandatory Commercial Organics Recycling/Composting

Beginning January 1, 2019, all commercial businesses and public entities that generate 4-cubic yards of trash per week must recycle their organic waste to comply with new mandatory commercial organics recycling established under California Assembly Bill 1826 (AB 1826). These new state regulations apply to schools, stores, restaurants, businesses, and for-profit or nonprofit organizations located in California. New regulations also require multifamily properties with 5 or more units to have green waste service.

Businesses can meet these requirements by:

  • Separating organic waste from other waste as part of trash collection. (See Mill Valley Refuse Service website link for organic waste collection services).
  • Recycling organic waste on site, or self-haul organic waste off site for recycling.
  • Subscribing to an organic waste recycling service that may include mixed waste processing that specifically recycles organic waste. (See Zero Waste website link below).

The City of Mill Valley is working to educate our local businesses on new state regulations, and will be visiting local businesses in the New Year to provide assistance. Please feel free to contact Danielle Staude, Senior Planner for more information (contact information above).                                                                                                                  

Additional Information: The mandatory commercial organics recycling law (AB 1826) was signed in 2014 to help achieve California’s aggressive recycling and greenhouse gas emission goals. California landfills receive about 30 million tons of waste each year, of which more than 30% is organic, which could be composted or used to produce renewable energy. Greenhouse gas emissions resulting from the decomposition of organic waste in landfills have been identified as a significant source of emissions contributing to global climate change. The City of Mill Valley continues to be a leader in sustainability practices, and has reduced its Greenhouse Gas emissions associated with waste generation by 26% since 2005. The new organics composting regulations will also work toward the City’s Zero Waste goal, wherein all materials are recycled, reused or repurposed.
