Joint Partnership with Marin Sanitary Service

CMSA and Marin Sanitary Service (MSS) have formed a public-private partnership, where CMSA accepts food waste from MMS that they obtain from restaurants, markets, and other eligible food waste generators.

This partnership provides many benefits:

  • Renewable resources that would normally go into a landfill are now diverted to our facility which transforms the food waste into biogas.

  • Reduced transportation distances, reducing greenhouse gases 

  • Using biogas to power the Agency facilities, reducing energy costs.

  • Processing food waste reduces the need for landfill space.

  • Fewer greenhouse gases are emitted as compared to disposing at a landfill.
