About 100,000 tons of green waste have been hauled out of county since Sonoma County’s last centralized compost facility closed in 2015.
A yearslong search for a new site to process much of Sonoma County’s yard and food waste may finally be over, potentially ending the need to haul almost 100,000 tons of organic materials to neighboring counties for composting each year.
Officials are now exploring the possibility of using a small piece of county-owned land in Windsor adjacent to the Sonoma County-Charles M. Schulz Airport to collect and compost green bin materials and commercial food waste to produce organic soil amendments in high demand by the local agricultural community.
The roughly 15-acre site at 5200 Slusser Rd. is part of a one-time county landfill decommissioned in 1971 and covered over with 9 feet of compacted soil.
Though its conversion to a commercial composting facility is still years off, an initial feasibility study of the site determined in 2022 there were no disqualifying physical or environmental hurdles.
If successful, selection of the site would put an end to a string of bad luck that has plagued local officials and their partners in providing a destination for organic waste just as an aggressive push is underway to keep as much as possible out of landfills, where they contribute to planet-warming greenhouse gases.
