The most sensible renewable energy

Biogas is a mixture of around 60% methane (CH4), 40% carbon dioxide (CO2) plus traces of other contaminant gases. The exact composition of biogas depends on the type of feedstock being digested. It is produced naturally when organic matter such as food waste from households, manure, or crops from agriculture is broken down by micro-organisms in anaerobic digesters (AD), landfill sites and wastewater treatment plants.

Upgraded biogas is most commonly known as either biomethane or Renewable Natural Gas (RNG). Upgrading equipment takes the raw biogas produced from the AD, removes the methane, carbon dioxide and other unwanted particles and separates them to produce a high purity of biomethane that can be used as a vehicle fuel in cars, buses or taxi’s or injected directly into the gas grid network.


Upgrading takes a problem for businesses, local authorities and the environment and creates a profitable and green solution

Upgraded to biomethane or RNG can be:

  • Used as a vehicle fuel
  • Sold to energy companies and injected back into the grid
  • Used to produce heat and or electricity on site

As a green fuel it is

  • Environmentally friendly with significantly lower emissions than fossil fuel
  • With the main ingredient, waste, it is truly renewable
  • Has no impact on the food chain, unlike crop-based biofuels

Upgrading to natural gas quality, which can be sold to energy companies, is often the most profitable use of the gas as many countries around the world support this through incentives
