Benefit-Cost Analysis of Potential Food Waste Diversion LegislationAnaerobic Digestion Facilities Processing Food Waste in the United States in 2015
(U.S. Environmental Protection Agency)
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.

Benefit-Cost Analysis of Potential Food Waste Diversion LegislationBenefit-Cost Analysis of Potential Food Waste Diversion Legislation (NYSERDA)
Based on the assumption that a processing facility would be centrally located in each county, and all generators comply, the report estimates potential net benefits ranging from $15.2 million for an all-compost scenario to $22.6 million for an all-anaerobic digestion scenario. These benefits could increase by 15-23% after the first year of implementation once equipment costs have been paid off.

Food Waste to Energy: How Six Water Resource Recovery Facilities are Boosting Biogas Production and the Bottom LineFood Waste to Energy: How Six Water Resource Recovery Facilities are Boosting Biogas Production and the Bottom Line (EPA)
As energy prices rise and as tighter regulations increase the cost of compliance, WRRFs across the county are tapping excess capacity while tempering rates. This report presents the co-digestion practices, performance, and the experiences of six such WRRFs. The report describes the types of food
waste co-digested and the strategies—specifically, the tools, timing, and partnerships—employed to manage the material. Additionally, the report describes how the facilities manage wastewater solids, providing information
about power production, biosolids use, and program costs.

Decarbonizing The Gas Sector: Why California Needs A Renewable Gas StandardDecarbonizing The Gas Sector: Why California Needs A Renewable Gas Standard (Bioenergy Association of CA)
California needs a Renewable Gas Standard (RGS). An RGS would require a small but increasing percentage of the state’s gas to be renewable. Modeled after the state’s Renewable Portfolio Standard, which has doubled renewable electricity in just over a decade, the RGS would require an increasing percentage of renewable gas, beginning with just 1 percent in 2020 and gradually increasing to 10 percent in 2030.

Water Utilities of the FutureWater Utilities of the Future: Energy Findings (WERF, NACWA, WEF)
This report shows national energy projections from the wastewater sector. It estimates the energy embedded in wastewater, characterizes it, and estimates costs and savings associated with moving wastewater facilities to become energy neutral or even energy positive. Key findings: There is five times the energy currently required for treatment of domestic wastewater nationwide available in the wastewater sector; maximizing the overall energy reduction for the largest 100 WRRFs in the U.S is a cost competitive option with other renewable energy (such as wind and solar); and demonstrates why the implementation of short-cut nitrogen removal technologies may be the best investment in water quality improvement.

Compressed Natural Gas and Compressed BiogasHygienic and sanitation requirements (pathogen kill) in biogas plants treating animal manures or mixtures of manures and other organic wastes (National University of Ireland)
The increasing trend towards co-digestion of food-processing wastes, sewage sludge and organics from municipal solid waste with animal manures in centralized or on-farm AD plants, coupled with the return of the treated biomass to farmland by landspreading, has raised valid questions re the potential dissemination of human, animal and plant pathogens. Detailed studies in Denmark have resulted in the development of indicator organism test procedures and in the setting of regulations which guarantee the sanitation status of AD-treated feedstocks. These regulations also lead to more efficient operation of centralized AD plants. Download >>
