Biofuel

Pyrolysis is the basis of several methods that are being developed for producing fuel from  biomass , which may include either crops grown for the purpose or biological waste products from other industries. ^[9] Crops studied as biomass feedstock for pyrolysis include native North American prairie grasses such as  switchgrass ( Panicum virgatum L.) and bred versions of other grasses such as  Miscantheus giganteus . Crops and plant material wastes provide biomass feedstock on the basis of their  lignocellulose portions.

Although synthetic diesel fuel cannot yet be produced directly by pyrolysis of organic materials, there is a way to produce similar liquid ( bio-oil ) that can be used as a fuel, after the removal of valuable bio-chemicals that can be used as food additives or pharmaceuticals. ^[10] Higher efficiency is achieved by the so-called  flash pyrolysis , in which finely divided feedstock is quickly heated to between 350 and 500 °C (660 and 930 °F) for less than 2 seconds.

Fuel bio-oil resembling light  crude oil can also be produced by  hydrous pyrolysis from many kinds of feedstock, including  waste from pig and turkey farming , by a process called  thermal depolymerization (which may, however, include other reactions besides pyrolysis).

[ edit ] Plastic waste disposal

Anhydrous pyrolysis can also be used to produce liquid fuel similar to diesel from plastic waste.
