Solid waste managers continuously investigate alternative methods for waste management to meet and improve their practice. As part of this process, innovative management techniques and strategies have been implemented to address a wide range of solid waste issues. In recent years, innovative management strategies have been of particular interest to solid waste officials responsible for the management of municipal waste combustor (MWC) ash. Historically, ash, a potentially reusable material, has been disposed of in monofill or co-disposal landfills. This practice has become costly to generators in terms of tipping fees and to landfill operators through the depletion of valuable landfill airspace. To address these concerns, solid waste managers in several states, including California, Florida, Pennsylvania, New York, and Tennessee, have implemented beneficial use programs in which ash is reused both within and outside of the landfill environment. To date, primary markets for ash include use as alternative landfill construction materials and as road base structural fill. While recycling of ash has been studied extensively over the past few decades, the combination of available technologies, the state and federal regulatory framework, and project economics are driving MWC projects to evaluate and, where feasible, implement beneficial use as part of their ash management programs.
