The anaerobic pyrolysis technology for organic matter sorted from municipal solid waste, often referred to as pyrolysis gasification technology, is a relatively advanced solid waste thermal treatment technique.

Its core principle involves heating sorted and enriched organic waste (such as kitchen waste, waste paper, plastics, rubber, straw, wood, textiles, etc.) to a specific temperature (typically between 350°C and 800°C) in an oxygen-free or strictly oxygen-deficient (oxygen-poor) environment. Through thermochemical action, the macromolecules of the organic matter undergo a series of complex chemical reactions including cracking, dehydrogenation, and polycondensation. This ultimately converts the waste into three types of high-value products: combustible gas (synthetic natural gas), condensed liquid oil (which can also be directly transported as high-temperature combustion gas), and solid carbon residue (biochar or carbon black).

This technology aims to achieve the "Three Modernizations" goals of municipal solid waste treatment: harmlessness, reduction, and resource utilization. It is therefore regarded as a more environmentally friendly treatment method.
