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 certified, CDFA listed, and is produced from local facilities that process material collected from residential green carts. Compost is usually delivered in bulk and residents are asked to bring their own containers and shovels.

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

Non-profit farm or educational garden?

Compost donations are also available for non-profit farms, educational gardens (e.g., schools), or habitat restoration on a case by case basis. Please reach out to Xinci at with an explanation of your need, how much compost you'd like, and where the compost should be delivered.

Suggest a new event location

Existing compost giveaway event locations are listed below. Please check our calendar for upcoming events. Most events are held in the spring and summer. If you do not see your desired location for an upcoming event, it may have passed for the year, or it has not yet been scheduled. Feel free to email Xinci at to ask.

  • Cazadero - Fort Ross School
  • Healdsburg - City Community Center
  • Petaluma - Petaluma Bounty
  • Santa Rosa - A Place to Play park
  • Sebastopol - Community Center Youth Annex
  • Sonoma/Springs - Larson and Garden parks
  • Windsor - Keiser park

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 must be large enough for a 20-40 yd truck to enter and turn around, and it must 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.
