Innovative dual-benefit recycling and sustainable management of municipal solid waste incineration fly ash via ultra-high performance concrete.

Millions of tons of municipal solid waste incineration fly ash are generated worldwide each year. Currently, landfilling is the primary disposal method, consuming vast land resources and posing significant risks of soil and groundwater contamination due to the high concentration of hazardous heavy metals. Thus, this study investigated the potential of recycling hazardous municipal solid waste incineration fly ash into non-hazardous ultra-high performance concrete for sustainable development.
