Ash Management and Resource Recovery in Waste-to-Energy
How waste-to-energy plants process incineration ash to recover scrap iron and produce recycled aggregates for construction.
Recovering scrap iron
Incineration ash is processed through screening and magnetic separation to recover scrap iron, which can be refined and reused in steelmaking or other metal products.
Recycled aggregates
The remaining ash is further treated into recycled aggregates with strong physical and chemical stability, suitable for roads, plazas, dikes and other infrastructure projects.
Closing the loop
Combined with flue gas heat reuse for leachate and wastewater treatment, ash recovery supports zero discharge and reduces additional operating costs.
