Here is a list of suitable feedstock for biogas valorization:


Farm waste:

  • Manure pig cow chicken

  • Waste water


Food industry waste:

  • Palm oil seed effluent

  • Sugar beet press pulp

  • Distillery waste water

  • Beer grain

  • Starch pulp

  • Milk whey

  • Fruit and vegetable juice press pulp


Municipal solid waste (MSW, Landfill gas)

  • Methanization

  • Waste water

Biogas is produced by the anaerobic degradation of organic compounds. It is generally composed of methane (CH4), carbon dioxide (CO2), water vapor (H2O) and various contaminants which depend on the feedstock biodegraded.


Major sources of biogas are municipal solid waste landfills which produce a biogas called “landfill gas” and is referred in the industry as (LFG), another major source of biogas is waste water treatment plants using anaerobic digestion.


Today, as we see the escalating cost of energy all over the world, many organic wastes are bio-digested or bio-methanized to recover the energy of these organic wastes in the form of clean biogas which can be further purified into natural gas which will be marketed as CNG or compressed natural gas.


To go from a raw biogas from any of these applications to a gas of commercial value, a biogas valorization system shall be implemented.

Feedstock for Biogas Production

AirScience Technologies was founded in 1993 from the merger of two companies, Canadian and American. After fifteen years of designing and building air pollution control systems for various industries, the company has refocused its activities on biogas purification and biogas flares.
