Anaerobic Digestion Facilities Processing Food Waste in the United States in 2015: Survey Results

Download the document.

In 2017, EPA surveyed operators of anaerobic digestion (AD) facilities that accept food waste about their operations in calendar year 2015. In July 2018, EPA published a report of the findings. This report, which is the first of three years of data collection, covers data for calendar year 2015 and summarizes data received from three types of AD facilities:

  • Stand-alone food waste digesters;
  • On-farm digesters that co-digest food waste; and
  • Digesters at water resource recovery facilities (WRRFs) that co-digest food waste.

The report includes information about the processing capacity of AD facilities as well as the total food and non-food waste processed in 2015. It also includes information about facility operations, pre-processing/de-packaging technologies, feedstock types and sources, biogas cleaning systems, biogas production and uses, and solid/liquid digestate uses.
