Biogas by Idex

Biogas is a renewable gas produced via methanization of organic matter, such as agricultural crop residue, and some types of industrial waste from the agri-food and livestock industries. These resources abound across France, and can be used to generate heat and electricity once they’ve been processed.

As a specialist in managing and recovering biomass for 40 years now, Idex enjoys unique partnerships with industrial companies and local authorities.

Biogas: what it is, and how it can benefit you

Biogas is the result of organic matter left to ferment in an oxygen-starved environment. It is primarily composed of methane and carbon dioxide. It can be burnt to yield heat and/or electricity, and it can also be purified before being injected into local natural gas distribution networks.

Biogas is a biomass-sourced green energy generated by methanizing different resources such as:

  • agricultural crop residuex,
  • green household waste,
  • mud from water treatment plants,
  • waste from the livestock and agri-food industries,
  • silt extracted from the bottoms of lakes and riverbeds.

This fermentation process takes place in a digester within which temperatures are meticulously controlled. The result is biogas, in addition to a viscous residue known as the digestate. The latter can be composted into a powerful fertilizer that bolsters local crops.

This biogas can then generate energy by combustion in a gas boiler, for example, which is then injected into the heating network. It can also be used to generate electricity when burnt in a gas engine. Most often, it is used to generate electricity and heat simultaneously via a cogeneration plant.
