Similar to traditional WtE processes, during pyrolysis waste is combusted and converted to energy
products. However, oxygen inputs, and, subsequently, oxidation within the pyrolysis system is
intentionally restricted.

This technology is primarily designed for waste destruction, not energy or byproduct generation like
other technologies. Pyrolysis temperatures range from 750 to 2200°F. Pyrolysis outputs include
biochar (a potential soil amendment with possible carbon sequestration applications), pyrolysis oils,
and a limited amount of syngas (“synthetic natural gas”), which is composed primarily of carbon
monoxide, hydrogen, methane, and carbon dioxide. Pyrolysis can be used in conjunction with
gasification as part of a two-stage process. Varying process parameters in the pyrolysis process can
result in varying proportions of generated solid, liquid, and gas outputs.
