Anaerobic Digestion Facilities Processing Food Waste in the United States

Download the report.

In 2014, EPA began building a dataset of names and locations of anaerobic digestion facilities processing
food waste to better understand the practice and prevalence of food waste digestion in the United States
(U.S.). In December 2016, EPA was granted the authority to survey digesters annually, and EPA has since
renewed that authority until 2025. This report is the fourth in the series. Each report includes data for
three types of AD facilities: (1) stand-alone food waste digesters; (2) on-farm digesters that co-digest food
waste; and (3) digesters at water resource recovery facilities (WRRFs) that co-digest food waste.
