Pyrolysis is a thermochemical term describing the decomposition organic (carbon-based) materials, by the application of heat, in the absence of oxygen the materials go through physi0-chemical separation into different molecules. As such the process can convert carbon-based materials into drop-in hydrocarbon biofuels, oxygenated fuel additives and petrochemical replacements.

Various materials can be processed with pyrolysis including plastics, tyres, biomass, wood, general waste, Most common heating of an organic material, such as biomass, in the absence of oxygen. Biomass pyrolysis is usually conducted at or above 500 °C, providing enough heat to deconstruct the strong bio-polymers mentioned above.
