Gasification is used to convert organic materials directly into a synthetic gas (syngas) composed of carbon monoxide and hydrogen. Gasification doesnʼt burn the material. It breaks the molecules apart with heat and a very small amount of air or oxygen and then recombines them to form syngas, a clean fuel similar to natural gas. It is these chemical reactions that makes gasification different from incineration. Syngas can be used to make fuels, chemicals, fertilisers, consumer products and generate electricity.

Thermal Gasification

Gasification is thermal decomposition of organic material through the application of heat and water in the absence of oxygen. The primary product is a combination of mainly carbon monoxide and hydrogen, which is called Syngas. This is a well known technology put together in a new package that has received greater interest from the market due to itʼs relative low investment and zero or small CO2 footprint. The waste treatment in combination with relief from CDM penalties improves the profitability further. Syngas is a valuable product that could be used as fuel or converted into other high value products.
