Co-Digestion Grant Program

The Department of Resources Recycling and Recovery (CalRecycle) administers the Co-Digestion Grant Program pursuant to Public Resource Code section 42999. The purpose of this competitive grant program is to lower overall greenhouse gas emissions by building new and expanded food waste co-digestion projects that increase the tonnage of California-generated organic waste diverted from landfills to a co-digestion system.

This program is funded by a General Fund allocation from the Circular Economy Package approved in the 2021 and 2022 Budget Act. This package supports a circular economy that recognizes waste as a resource shifting the state’s focus to a more resilient and renewable economy in California.  These funds will support the implementation of goals to reduce short-lived climate pollutants, including advancing organic waste infrastructure.

It is also funded in-part by California Climate Investments, a statewide program that puts billions of cap-and-trade dollars to work reducing greenhouse gas emissions, strengthening the economy and improving public health and the environment— particularly in disadvantaged communities. The Cap-and-Trade program also creates a financial incentive for industries to invest in clean technologies and develop innovative ways to reduce pollution. California Climate Investments projects include affordable housing, renewable energy, public transportation, zero-emission vehicles, environmental restoration, more sustainable agriculture, recycling and much more. At least 35 percent of these investments are made in disadvantaged and low-income communities. For more information, visit California Climate Investments.
