Panelists at the August 16 Solid Waste Association of North America’s WASTECON 2012 said that reusing the ash generated from waste-to-energy facilities could help offset the economic costs that frequently discourage communities from building the plants. Storage demand for ash materials and developing technologies could help to offset costs, but significant obstacles, including the cost of land and environmental regulations, remain. Panelists also charged that economic markets and public demand for the recovery of materials, rather than government regulation, will drive innovation in the field.
