• Abstract:
  Municipal solid waste incineration (MSWI) generates millions of tons of ash each year. In European and Asian countries, this ash has been recycled into road beds, asphalt paving, and concrete products — encouraged and enforced by standards, management practices, and legal requirements — thus preventing vast amounts of ash from going to landfills. Many studies have shown both benefits and minimal environmental impact of using MSWI ash. However, persistent uncertainty about engineering properties and inconsistency in federal and state regulations in the U.S. have hindered MSWI ash recycling, and most ash ends up in landfills. In this project, University of Central Florida researchers reviewed current management practices, existing regulations, and environmental consequences of MSWI ash use around the U.S. and the world.
