Sonoma County officials resurrect decade-long effort for local composting facility

More than a decade after Sonoma County lost its commercial composting facility, county officials are moving forward with a proposal for a new regional site northwest of Santa Rosa they say could process most of the county’s residential green bin waste locally.

At an April 28 meeting, the Sonoma County Board of Supervisors authorized the environmental review for a prospective compositing facility at 5200 Slusser Road, immediately west of the county’s airport at the former county landfill site.

Should the facility move forward, the site would process up to 70,000 tons of residential green bin waste annually, accounting for around 80% of the total amount of compostable waste generated across the county.

County officials say the centrally-located facility could help reduce truck traffic and greenhouse gas emissions associated with hauling the material out of the county, while fulfilling state requirements to divert organic waste from landfills.
