Conservation & Development — Solid Waste and Recycling
Collection oversight covers portions of unincorporated Contra Costa County; use the county recycling service directory to confirm the provider for an address.
The County’s directory separates three residential receiving areas and warns that only some listed materials are accepted at each facility. Contact the correct receiving program before transport.
Service area: Household/material-specific programme or referral only. Residency, customer eligibility, materials and receiving-site availability must be checked with the named programme; this is not unrestricted all-county disposal access.
