Topic:       Lessons and Innovations from the Performance of Modern Municipal Solid Waste
                 Landfills with Emphasis on Long-Term Post-Closure Care


Design, construction, operation, and closure of municipal solid waste (MSW) landfills have been regulated by the United States Environmental Protection Agency (USEPA) since the 1990s. These regulations currently reflect the “law of the land” and the solid waste industry has learned several valuable lessons regarding the performance of these facilities, but finds itself asking about the long-term care and responsibility of this essential infrastructure component. This presentation will briefly highlight many of the lessons garnered from the >30 years of modern landfill operations and looks into future of landfills. The presentation will provide insight regarding sustainable and innovative long-term solutions to questions commonly asked to USEPA, including alternative closure concepts, beneficial reuse of landfills, and techniques that address very long-term, post-closure care of these facilities while being protective of human health and the environment.
