Energy recovery from non-recyclable waste materials to energy forms such as heat, electricity and/or fuel through a variety of processes is known as waste to energy. The conversion is utilised through a variety of processes, where most common are, gasification and pyrolysation.
Gasification is a process that converts organic or fossil fuel based materials into carbon monoxide, hydrogen and carbon dioxide compounds. This is achieved by very high temperatures, without combustion, but with a controlled amount of oxygen. The advantage of gasification is that using the syngas is potentially more efficient than direct combustion of the original fuel. Syngas may be burned directly in gas engines, used to produce methanol and hydrogen, or converted into synthetic fuel.
Pyrolysis is a thermochemical decomposition of organic material at high temperatures in the absence of oxygen. It involves the simultaneous change of chemical composition and physical phase, and is irreversible.
