Fly Ash

Fly Ash and APC Residues (Air Pollution Control Residues) are the by-products of the flue gas cleaning process and are commonly combined. Fly Ash, which is a light-weight ash, can be recovered and used in a manufacturing process, such as cement manufacture. APC residue is typically a mixture of ash, carbon and lime. It is a Hazardous Waste which is currently disposed of at a Hazardous Landfill or undergoes further processing such as washing or stabilisation to send to a Non-Hazardous Landfill^[1].
