Pyrolysis Gas / Gasification
Pyrolysis is where a substance is heated very strongly in the absence of oxygen. Under these conditions organic matter such as food waste, packaging and fibres tend to break down quickly into tars, ash and a mixture of gases.
With the drive to use the environmentally friendly gas hydrogen at the top of the agenda, it will soon be economic to remove the hydrogen from the pyrolysis gas stream. Recent advances with membrane gas separation technology, together with robust compression equipment, will make this next step successful in the near future.
