Analysis of Aggregates Reclaimed from York County, Pennsylvania Municipal Solid Waste Incineration (MSWI) Bottom Ash for Beneficial Use
Waste-to-energy (WtE) is an efficient and sustainable solution to manage and reduce the increasing volume of municipal solid waste (MSW) generated in the United States today. WtE facilities combust MSW to generate superheated steam that is harnessed to create renewable energy (electricity). However, the United States is the world leader in the production of municipal solid waste incinerator (MSWI) ash. MSWI ash is a WtE byproduct requiring responsible and costeffective management. Today, conventional recycling of MSWI ash in the United States does not exist. Instead, MSWI ash is primarily disposed of in landfills after large ferrous and non-ferrous metals have been removed, forfeiting the opportunity to recover any valuable materials, such as coarse and fine aggregates, remaining in the residual material. This work explores the efforts undertaken to recycle and reuse reclaimed aggregates from MSWI bottom ash (MIBA) generated at the WtE facility in York County, Pennsylvania. An overview of the processes involved in the generation and subsequent processing of MIBA are presented. The physical and chemical properties of reclaimed aggregates are compared to those of natural aggregates to highlight their potential for use in construction materials, as governed by the Pennsylvania Department of Environmental Protection General Permit WMGM061. The beneficial use projects and research efforts explored by the York County Solid Waste Authority (YCSWA) and its commercial and institutional partners are discussed and evaluated. Additionally, analysis substantiating the commercial viability, environmental benefit, and sustainability of using reclaimed aggregates from MIBA in construction materials is conducted.
