Integrated Waste

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

What we do

The SPI 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.

Disposal Sites

Republic Services of Sonoma County, Inc. operates the CDS, located outside of Petaluma, as well as four smaller transfer stations, located in Annapolis, Guerneville, Healdsburg, and Sonoma. See More

Reuse and Recycling Center

Recyclables such as scrap metal, cardboard, glass, metal and plastic containers, and newspaper can be conveniently unloaded at the recycling drop-off center, located at the Central Landfill on Mecham Road outside of Petaluma. See More

Household Toxics Disposal

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

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 for a significantly lower cost than disposing of garbage at the Annapolis, Guerneville, Sonoma, and Healdsburg Disposal Sites.   Please note the Central County Disposal Site is not accepting recyclable wood at this time.
