Solid wastes are burned at high temperatures in sizable furnaces during the pyrolysis process, which results in much less of the waste's volume and weight being reduced and the formation of ash. Depending on the type of material, it is estimated that the volume of the waste is reduced by about 95% while the weight is reduced by about 80% to 85%. Hazardous waste, municipal waste, biomedical waste, and medical waste can all be extensively burned.
This process' energy recovery can be used to produce electricity. Sludge treatment, furnace combustion, and energy recovery comprise the three main phases of Pyrolysis. Usually, incinerators operate in remote locations without any human occupants.
