Incineration is another solution for waste disposal that has been common in industrialized countries for many years. The role of incinerators becomes even more apparent when it comes to hazardous and hospital waste disposal. Waste incineration is not really a biomass energy production technology, but a method that generates energy with a waste source and the use of combustion or gas technologies.

Incinerators are defined as units that heat oxidize waste and reduce carbon residues as much as possible. The products of incinerators are carbon dioxide, water, ash and heat from combustion. In addition, air pollutants such as sulfur and nitrogen compounds and various halogens and heavy metals (such as cadmium, mercury, etc.) are other combustion products.

For many wastes, incineration is one of the best or most essential ways to manage waste. In most cases, incineration is the only processing step for many solid and liquid wastes, and solid or liquid wastes remain for later disposal.
