Compost Giveaways

Free compost is available for Sonoma County residents every year. Collaborating with the municipalities, community volunteers, and partner organizations, Zero Waste Sonoma organizes compost giveaway events throughout the County. The compost is certified USDA organic, OMRI listed, CDFA listed, and is produced from local facilities that process material collected from residential green carts. The compost does not contain biosolids or manure. Compost is usually delivered in bulk, and residents are asked to bring their own containers and shovels. Residents are welcome to attend any of the events around the County, but we encourage residents to go to the ones closest to them to reduce vehicular greenhouse gas emissions.

The compost will come from one of three facilities. For more information about the compost, including testing data sheets, refer to their websites below.

Disclaimer: The compost is available for free, on a first-come, first-served basis, “as is” and with all faults. Zero Waste Sonoma makes no warranty or guarantee, either express or implied, that the compost will be effective, useful, or safe in any manner. By attending the event, you are participating at your own risk,. People will load compost into their vehicles using shovels and other equipment and cars will frequently stop. Please drive slowly and proceed with caution. Volunteers are available to assist you with loading compost.

If you wish to suggest a new location, please type it in the message box below. Leave your contact information so that we may follow up to determine whether it will be suitable. The site entrance/gates must be at least 9 feet across for truck clearance, and there must be enough room for the truck to enter and turn around to unload. The site should also be big enough to allow for people to get out of their cars and shovel compost safely. Ideally, the site should also have at least two exits for traffic flow.

Want to help? Check the box and leave a message below about how much you'd like to be involved. An event is more likely to happen if we have one or two volunteers to help with the planning and being on site on event day to direct other cars.
