The incineration of municipal solid waste (MSW) produces byproducts known as MSW incineration (MSWI) ash. The reuse of MSWI ash as a construction material prevails in several areas of the world, namely Europe and Asia, however, reuse in the United States (US) lags due to regulatory requirements for disposal practices. Developing a recycling program for MSWI ash provides an alternative end-of-life disposal scenario for material currently landfilled and supplements the reliability of mining of natural aggregates.

- - The study examines the use of weathered municipal solid waste incinerator bottom ash (MSWI BA) as a substitute in road base materials, mixed with natural or recycled aggregates to reduce environmental risks.
- - Findings show that increasing the proportion of MSWI BA in blends leads to a significant reduction in leaching of metals, particularly aluminum and antimony, with blends containing 85% recycled concrete aggregate achieving over 90% leaching reduction.
- - The presence of calcium-bearing minerals in recycled concrete helps immobilize hazardous metals, making the blending of MSWI BA with conventional aggregates a promising method for safe recycling in road construction.
