Pyrolysis and Gasification
Pyrolysis and gasification are similar processes they both decompose organic waste by
exposing it to high temperatures and low amounts of oxygen. Gasification uses a low
oxygen environment while pyrolysis allows no oxygen. These techniques use heat and an
oxygen starved environment to convert biomass into other forms. A mixture of
combustible and non-combustible gases as well as pyroligenous liquid is produced by
these processes. All of these products have a high heat value and can be utilised.
Gasification is advantageous since it allows for the incineration of waste with energy
recovery and without the air pollution that is characteristic of other incineration methods.
