According to BioCycle the US now has over 4,713 Organic Recycling facilities, BioCycle editors collected the most recent data has United States had compiled about organics recycling activities. A one-page questionnaire was completed by 43 states and the District of Columbia, primarily by officials in state solid waste agencies whose responsibilities include organics recycling. Data submitted was from Calendar Years 2015-2017.
The 2017 State of Organics Recycling In The U.S. survey requested information on both composting and anaerobic digestion infrastructure and regulations. While several solid waste agency officials who responded had data on anaerobic digestion activity in their state, the majority did not, as municipal and on-farm anaerobic digestion operations typically fall under the purview of other state agencies. As a result, BioCycle utilized other sources to collect data on anaerobic digestion.
The Big Picture
The 2017 State of Organics Recycling In The U.S. snapshot survey found a total of 4,713 composting facilities. Table 1 breaks down that total number by facility types. Yard trimmings composting represents the largest number of operations in the U.S. — 2,698 or 57.2 percent of all facilities in the U.S. There are 249 composting sites that process yard trimmings and food scraps, and 620 that process multiple organics, which include feedstocks such as yard trimmings, food scraps, livestock manure and industrial organics. Massachusetts, for example, reports 185 composting facilities processing multiple organics and did not include any sites in the yard trimmings only or yard trimmings and food scraps only categories.
As noted, data on anaerobic digestion facilities came primarily from other sources — the U.S. EPA AgSTAR database for farm digestion (last updated in August 2017), the Water Environment Federation database on anaerobic digesters at municipal wastewater treatment plants (2014 data), and the Water Environment & Reuse Foundation for data on codigestion at wastewater treatment plants (2016 data). Only four of the 43 states completing the survey provided their own AD data.
