Mandatory Recycling and Organics Law

In 2016, Governor Brown signed Senate Bill 1383 into law to keep food and other compostable materials ("organics") out of landfills to reduce emissions that contribute to climate change. Starting January 2022, all California residents and businesses are required to compost all organic waste. In addition, this law will require food-producing businesses to donate excess edible food to reduce organic waste. Please visit the Cal Recycle website for more information on the new law.

Why is the law important?

Climate change has contributed to severe drought, wildfires, and extreme heat in California. Methane, a potent greenhouse gas that contributes to climate change, is emitted into the atmosphere when compostable materials like food, paper, and yard waste are buried in landfills instead of composted or recycled. In addition, when food scraps and yard trimmings are sent to a composting facility instead of a landfill, they are turned into compost, a valuable resource farmers and gardeners use to grow healthy food. The State law aims to reduce organics going to landfill by 75% by January 1, 2025.

What should I compost?

If you can eat it, you can compost it! Remember, that all other organic materials are also compostable, not only food waste. See below for examples of what to put in your composting bin:

  • Food and food scraps such as fruit, vegetables, meat, bones, shells, dairy, and leftovers
  • Plant material such as grass, flowers, leaves, branches, and wood
  • Food-soiled paper such as paper towels, napkins, and delivery pizza boxes

Items that can be added to a compost cart

What shouldn't I compost?

The City of Larkspur's compost hauler WM Earthcare produces high quality compost used to grow organic food. Which is why,  we CANNOT accept any plastics labeled as compostable or bio-degradable because they take twice as long to breakdown as the natural compostable materials.

Please DO NOT put any of the following items in your green cart for compost:

  • NO compostable or bio-degradable plastics, bags, cups, containers, and utensils.
  • NO diapers, pet waste, human waste and poison oak

Please visit the  Marin Sanitary Service website for a complete list of what you can and should not be put into your compost bin.
