Incineration is an old and polluting technology used to simply burn household trash and waste. Incineration produces a limited amount of heat and is no longer considered a viable alternative. Many of these old facilities are being upgraded to gasification facilities.
Gasification is clearly the way of the future in both terms of efficiency and the environment. Gasification is a flexible and clean energy technology that can turn a variety of feedstock into energy, helping to reduce dependence on carbon based energy sources providing a clean alternative source of electricity, fertilizers, fuels, and other useful by-products.
