Pyrolysis
The most acceptable route to recycling wastes in the future may be through pyrolytic techniques in which wastes are heated in an air-free chamber, at temperatures as high as 1650 °C. Pyrolysis seems to provide several advantages over incineration. These systems encounter far fewer air pollution problems, handle larger throughputs resulting in tower capital costs, provide their own fuel, degrade marginally burnable materials, and have the added potential for recovering chemical or synthesis gas.
