Feasibility Study of Anaerobic Digestion of Food Waste in St. Bernard, Louisiana. A Study Prepared in Partnership with the Environmental Protection Agency for the RE-Powering America's Land Initiative: Siting Renewable Energy on Potentially Contaminated L

摘要

The U.S. Environmental Protection Agency (EPA) Office of Solid Waste and Emergency Response Center for Program Analysis developed the RE-Powering America's Land initiative to reuse contaminated sites for renewable energy generation when aligned with the community's vision for the site. The former Kaiser Aluminum Landfill in St. Bernard Parish, Louisiana, was selected for a feasibility study under the program. Preliminary work focused on selecting a biomass feedstock. Discussions with area experts, universities, and the project team identified food wastes as the feedstock and anaerobic digestion (AD) as the technology. The brownfield site is located in Chalmette, Louisiana, adjacent to the St. Bernard Port on the Mississippi River. The brownfield site is 39 acres; however, the center and southern area of the site is a mound with hazardous spent potliner (SPL) wastes. This leaves approximately 19 acres available for development evenly split on either side of the mound. Infrastructure, including rail, water, electricity, and natural gas pipes, are at or adjacent to the site.
