More Than A Compost Program
Sonoma Compost operates the Organic Recycling Program on behalf of the Sonoma County Waste Management Agency. We accept yard trimmings and vegetative food discards that are placed in curbside containers by local residents. Yard trimmings are also delivered directly to our site by landscapers, tree trimmers and the public. In addition, we accept selected agricultural byproducts from local farms, wineries and food processors.

Sonoma CompostThese materials are carefully made into premium quality organic compost and mulches, as well as bio-fuel that is used to generate electricity. Tree limbs are cut to the right length and split, seasoned and sold as affordable firewood.

We also accept wood scraps provided it is unpainted and not pressure-treated. After re-useable lumber is sorted out, the balance is converted into our Path Mulch and bio-fuel.

Working For You…The Sonoma County Waste Management Agency
Our Waste Management Agency includes representatives from the County of Sonoma and its cities, and serves the interests of over 485,000 local residents. Their mission is to meet waste diversion goals established by the state of California. In addition to yard and wood scraps, the Agency deals with a number of waste issues, including household hazardous waste, public education, public event recycling, and long-term waste management planning.

Sonoma Compost Promotes Use of Organic Waste Materials
Since implementation in 1993, Sonoma Compost has successfully diverted approximately 1,460,000 tons of yard trimmings and wood waste from landfills. This represents approximately 18% of the County’s total waste generated in that time. With the help and support of local residents, we have extended the life of our local landfill and are reducing the amount of waste needing to be trucked to out of county to surrounding landfills.

Economic Benefits
Because it’s much cheaper to recycle yard and wood debris locally, than to transport these materials to out of county landfills, local residents pay less to drop these materials off at the County’s Central Landfill.

Similarly, trash hauler rates for organic materials are lower because haulers pay less to deliver curbside collected yard waste to Sonoma Compost’s facility than to haul it long distances to out of county landfills.
