Strategy for Beneficial Use of Stoker‐Boiler Coal Ash
Publication: Journal of Environmental Engineering
Volume 120, Issue 2
Abstract
Commercial coal ash makes up a large amount of the material in United States landfills. Studies to promote recycling of these materials are conducted on a case‐by‐case basis. The objective of the present work is to provide ash generators with a strategy for developing ash‐recycling options in order to reduce landfill usage and create profits from the sale of their by‐products. A protocol is used to identify beneficial use options for many types of nonhazardous, industrial‐process by‐products. In the present paper, the protocol is demonstrated with stoker‐boiler coal ash recycled in construction products, mainly concrete and concrete block. The protocol contains five steps: a preliminary characterization, a market survey, screening tests and pilot production, an environmental‐impact assessment, and a cost analysis. These steps are required before any potential use can be recommended to a generator.
