Often used to treat medical and hazardous wastes, incineration destroys organic substances contained in waste materials by using combustion. When waste is incinerated, it is converted into ash, flue gas, and heat. Incineration can also be paired with energy recovery in waste-to-energy technologies such as pyrolysis, gasification and anaerobic digestion.
Rotary kiln incinerators are frequently used by municipalities and large industrial plants to volatize and combust waste. These systems are excellent for processing mixed wastes, which can include solid, sludge, and liquid waste.
Like coal fired power plants, incineration produces fly ash and bottom ash, which can be safely recycled by using the proper process. Additionally, heat produced by an incinerator can be used to generate power for itself, lowering costs and improving efficiency.
