Waste to Energy
Waste to energy is a way for energy generation in the form of heat and electricity from the waste treatment. It is a means of energy recovery. Most energies from waste forms create power and heat straightforwardly through ignition, or produce combustible fuel commodity, for example, methane, methanol, ethanol or engineered fills. Waste to Energy process technology includes fermentation, which can take biomass and create ethanol, using waste cellulosic or organic material. In the fermentation process, the sugar content in the waste material is changed to carbon dioxide and alcohol, in the same method used in making wine. Fermentation occurs with no air present. Esterification is also done using waste to energy technologies, and the result of this process is biodiesel. Few pyrolysis processes need an outside heat source which can be supplied by the gasification process, making the combined process self-sustaining.
