Effective July 1, 2012 State law requires businesses that generate four cubic yards or more of waste per week or multi-family residential dwellings (complexes) of five units or more to arrange for recycling services.  With the passage of this Mandatory Commercial Recycling law (Chapter 476, Statutes of 2011 [Chesbro, AB 341]), California is one of the first states in the nation to enact a statewide program to reduce greenhouse gas emissions by diverting commercial solid waste from landfills. AB 341 also establishes a state-wide goal to divert 75% of solid waste away from landfill by the year 2020.

According to 2008 Statewide Waste Characterization data, the commercial sector generates nearly three fourths of the solid waste in California, with much of the materials that are disposed of by the commercial sector being readily recyclable.

Businesses and multi-family complexes in the unincorporated areas of Contra Costa County shall separate recyclable materials from garbage and choose from one or more of the following options:


1.    Subscribe to recycling service from the trash collector authorized to service your account (click to find your local trash and recycling collector)

2.    Self-haul to your local recycling facility(ies) (click to find the right recycling facility near you) *Requires an Exemption form be completed and submitted to DCD for approval

3.    Arrange for the pick-up of the recyclable materials from a person or vendor that does not charge for service. *Requires an Exemption form be completed and submitted to DCD for approval


A property owner of a commercial business or multi-family complex may require tenants to separate their recyclable materials to aid in compliance with this section.

*A site visit from County staff may be required when submitting an exemption form  


Your business may already be in compliance
Many businesses in the unincorporated County areas may already be in compliance with the new law. If your business is already recycling then you are in compliance. Thank you for recycling. If your business subscribes to less than four cubic yards of garbage service per week then you are not subject to this recycling requirement, however the County encourages you to consider adding recycling services as it may reduce your trash fees and divert valuable resources from the landfill.


Tenants in office buildings and strip malls can share recycling services

In an office building or a strip mall with multiple businesses, if the complex as a whole generates four or more cubic yards per week of garbage, then the individual businesses in that complex are required to recycle. Property managers and tenants should work together to ensure successful recycling program implementation by each business in the complex. Often property managers arrange for recycling services for their tenants.

The company responsible for collecting trash and recyclables at your business or multi-family complex varies based on location.  Local trash collector is often best suited to collect your recyclables.  In many cases, the only company authorized to collect recyclables is the one that also provides routine trash pick-up (unless recyclables picked up free of charge).  Click the link for your community/area below to learn about the routine recycling collection services available for your location.  Most service providers will arrange to provide “free” technical assistance, including waste assessments, to help business capture more recyclable materials currently being discarded as trash.  Not all collectors list as much information on their websites as others, so be sure to call your collection company if you don’t find what you are looking for on their website.

Contra Costa County oversees collection service agreements for the majority of the unincorporated area.  Agencies that govern contracts for the remaining unincorporated communities are listed below.

Local agencies have designated one recycling collection service provider for each unincorporated service area.  The designated collection service providers have the exclusive contractual right and responsibility to provide commercial recycling and other routine collection services within their respective unincorporated service areas (except part of Central County).  The Central Contra Costa Solid Waste Authority has multiple approved (permitted) recyclers who are qualified to provide commercial recycling collection services in a portion of Central County (see below).
