Where should I drop off green waste?

Drop-off recyclable yard debris and comingled food scraps at the Annapolis, Guerneville, Healdsburg, and Sonoma Transfer Stations. Please note: wood waste, yard debris, and food waste are not accepted at the Central Disposal Site.

What happens to my green waste?

Sonoma Compost Company closed October 15, 2015. The yard debris collected from County Refuse Disposal sites and from weekly pick up of residential curbside green waste now gets transferred from the Central Disposal Site and other transfer stations to composting facilities located outside Sonoma County. Currently, these two composting facilities are Redwood Landfill and Cold Creek Compost

Will the municipal composting program ever return to Sonoma County?

The Agency is working on development of a permanent facility to allow composting, including wood waste processing, to return to Sonoma County for the long term. For details about the necessity to close Sonoma County’s Municipal Composting Facility, see News release May 22, 2015, Federal Lawsuit Leads to Closure of Sonoma County’s Municipal Composting Facility.

On May 31, 2017 the SCWMA issued an RFP for proposals from entities with demonstrated experience and qualifications in owning and operating organics processing facilities, accepting organic material, and processing and diverting organic material to secure organics processing capacity for organic materials generated within Sonoma County. The selected Proposer(s) would be paid a per ton rate that is set by through an agreement with the SCWMA, in exchange for siting, owning, building, and managing the facility, as well as processing the organic materials, and marketing the any finished products produced.

On August 15, 2018 the SCWMA Board authorized staff to enter into exclusive negotiations with Renewable Sonoma to enter into an agreement to develop a new organics processing facility in Sonoma County.
