About Us

Integrated Waste is a division of the  Sonoma County Department of Transportation & Public Works (TPW). Our mission is to provide ecological solutions to solid waste disposal, natural gas recovery, electrical generation, recycling, and community hazardous waste disposal.

The TPW Integrated Waste Division owns the Sonoma County Central Landfill, which houses facilities for recycling, material reuse and natural gas and electrical generation. It owns five refuse transfer stations, oversees the regulation of two commercial hauling companies and maintains closed landfills.

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. See More

Wood Recycling

Recyclable wood can be dropped off at any of the County Disposal Sites for a significantly lower cost than disposing of garbage. For disposal locations and hours of operation, please see Disposal Sites
