Pyrolysis is the decomposition of organic matter at elevated temperatures (300 and 1300 °C) in the absence of oxygen at atmospheric pressures. The useful products generated are a charcoal-like biochar solid product, a bio-oil formed from ‘condensable’ volatile substances and ‘non-condensable’ gases which may include both carbon dioxide and methane.
