Incinerator bottom ash is a product from waste-to-energy and incineration facilities; it’s the material that does not fully combust and is discharged after incineration. Often this bottom ash contains precious metals and heavy metals which can be a challenge for disposal facilities. However, if these metals are selectively recovered, they can be sold directly to recyclers and metal refiners.
Sepro Mineral Systems has developed a proprietary system for wet processing of fine incinerator bottom ash (< 3mm or 1/8”) which has the following significant benefits:
Selective recovery of precious metals and heavy metals
Wet processing which drastically reduces, if not eliminates, dust creation during processing
The ability to process either stockpiled or directly fed bottom ash
Easy integration into existing processes due to small footprint requirements
Cleaner final ash for safe use in construction materials.
