Waste to Energy (WTE) is the process of generating fuels, electricity and heat from wastes. It is one of the most important energy conversion steps for a sustainable environment. The energy produced from wastes are considered renewable energy.
Wastes that can be used in Waste to Energy plants are usually municipal wastes (non-recyclable food and green wastes), agricultural wastes (animal wastes, crops) and biomass (wood).
Most of the plants use incineration (combustion) to produce heat and then use the heat to generate steam and electricity. Some of the plants use gasification technology to produce syngas. Syngas could be used in gas engines to produce power or converted into synthetic fuels such as diesel via Fischer-Tropsch technique or gasoline via methanol to gasoline conversion. Another technology is using anaerobic digestion to produce biogas which has high methane content. Biogas can be blended in natural gas grids, combusted in gas engines to produce power or converted to biofuels (Bio-LPG, Bio-DME).
The emissions of Waste to Energy plants are strictly regulated. Modern plants remove hazardous materials from the waste before conversion.
