The elements that makeup biogas are methane (CH4), which determines its energy content, carbon dioxide (CO2), small quantities of hydrogen sulphide (H2S) and ammonia (NH3).

The production of Biogas for the world’s energy needs, increasingly focuses on renewable sources and replaces common fossil fuels such as coal, oil and natural gas.

Before Biogas is fed into the grid, e.g. for electricity, heat or biomethane production, it must undergo filtration, to remove its high-water vapour content and screen out other impurities.
