Do you recycle and want to reduce more waste and save more money?  Start organics (compost) collection and become a 4R Star!  In CVSan, collection rates for organics cart service are much cheaper than garbage, which can add up to a lot of savings.  Many restaurants that recycle, but are not yet participating in organics, find such a large amount of organics (food and food-soiled paper) in the garbage that it’s easy to start and save.  Even if you’re not a restaurant you can participate in organics and you may be able to save money as well.

What is organics, really?  Click here to view our helpful flyer for what goes in the organics cart or bin.  CVSan’s Commercial Organics program provides everything you may need to see results and collect as much organics as possible.  WMAC and CVSan are available for assessments by appointment to help you start up or fine tune your organics program and save you money.  Please call CVSan at 510-537-0757 to get started.

California's Mandatory Commercial Recycling Law and the Alameda County Mandatory Recycling Ordinance

What You Need To Know

Information about the new laws:

With the passage of (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. According to 2008 Statewide Waste Characterization data, the commercial sector generates nearly three fourths of the solid waste in California, with much of the commercial sector materials disposed in landfills readily recyclable.  AB 341 also establishes a state-wide goal to divert 75% of solid waste away from landfill by the year 2020.

In 2012, the Alameda County Waste Management Authority (ACWMA) introduced the Mandatory Recycling Ordinance 2012-01 to expand on the State recycling law. The Ordinance is designed to help Alameda County reach the long-term goal of reducing waste by ensuring that recyclables and compostables make up less than 10 percent of material sent to landfill by 2020.

Mandatory recycling in the Castro Valley Sanitary District service area has been effective since July 1, 2014 for all businesses and institutions, as well as multi-family properties with 5 or more units. 

Recyclable Materials covered by the Ordinance include: newspaper, white paper, mixed recyclable paper, recyclable glass food and beverage containers, metal (aluminum and steel) food and beverage containers, PET (#1) and HDPE (#2) plastic bottles.

Effective January 1, 2016, businesses and institutions that generate “significant” quantities of organics such as restaurants and grocery stores and for multi-family properties, organics (food scraps, compostable paper, and plant debris) must also be kept separate from the garbage.  

For a limited time, the Alameda County Waste Management Authority is offering free indoor green bins to qualifying Alameda County businesses and institutions, for the collection of food scraps, compostable paper and plant debris (“organics”). A variety of containers and lids are available–up to a value of $500 per approved business! Apply at

Businesses and multi-family complexes in Castro Valley Sanitary District shall separate recyclable materials from garbage and choose from one or more of the following options:
