The California Department of Food and Agriculture (CDFA) is now accepting applications for the Dairy Digester Research and Development  Program (DDRDP).

An estimated $11 million in competitive grant funding will be awarded to provide financial assistance for the installation of dairy digesters that result in reduced greenhouse gas (GHG) emissions and provide other environmental benefits. Application deadline is Feb. 23.

Authorized by the Budget Act of 2014, CDFA was appropriated monies from the Greenhouse Gas Reduction Fund to provide financial assistance for the installation of dairy digesters in California, designed to reduce GHG emissions. 

“Digester technology is precisely the kind of innovation that California farmers are known for,” said CDFA Secretary Karen Ross. “It promotes low carbon fuels, agricultural energy efficiency and other operational advantages. We are very encouraged about the potential of this program.” 

Agricultural regions, including disadvantaged communities in the Central Valley as identified by the California Environmental Protection Agency using CalEnviroScreen, will benefit from reduced GHG emissions and improved air and water quality protections. Additionally, Central Valley dairy farmers will have revenue generation potential by converting agricultural waste into clean energy that can be used on-farm or off-site as transportation fuel or electricity.
