Integrated Waste is a division of Sonoma Public Infrastructure and provides ecological solutions to solid waste disposal, natural gas recovery, electrical generation, recycling, and community hazardous waste disposal.

The Integrated Waste Division owns numerous solid waste facilities across the County including the Sonoma County Central Disposal Site (CDS) and five (5) refuse transfer stations, operated by Republic Services in a public-private partnership.

These sites house facilities for recycling and material reuse along with natural gas and electrical generation at the CDS. The Division also oversees the regulation of two commercial hauling companies and maintains seven (7) closed landfills.

Funding

The Integrated Waste Division is funded by usage fees from the Central Disposal Site and Transfer Stations, as well as franchise fees from waste hauling companies. It uses these funds for activities such as maintaining closed landfills and providing oversight of operational and collection contracts.

Proposed Sonoma County Compost Facility

Sonoma County is exploring a proposed compost facility on County-owned land at 5200 Slusser Road in Windsor to process local organic waste collected in residential green bins. The facility would use modern systems designed to control odors and manage stormwater and leachate while reducing truck travel and supporting California’s SB 1383 organics recycling requirements. The project is still in the proposal stage, and environmental review and public input will occur before any final decisions are made.

Additional Services

Household Hazardous Waste Disposal

Located at the Central Disposal Site, the Household Toxics Facility is operated by Clean Harbors through a contract with Zero Waste Sonoma. Provide Address.

Natural Gas Recovery

With nearly 24 million cubic yards of solid waste in place, the Central Disposal Site produces about 2,500 standard cubic feet/minute (scfm) of landfill gas. This gas is collected from 150 collection wells and transported through 4 miles of pipeline to the landfill gas-to-electricity facility and to the landfill gas-to-vehicle fuel pilot project.

Wood Recycling

Recyclable wood can be dropped off at any of the County Disposal Sites for a significantly lower cost than disposing of garbage. Please note the Central County Disposal Site is not accepting recyclable wood currently.
