What is biogas?

Biogas is a mixture of methane and carbon dioxide, as well as water vapour, nitrogen, oxygen, hydrogen, ammonia and hydrogen sulphide, and is the end-product of an anaerobic fermentation process. It can be obtained from manure and other organic substances. In a system known as a digester, which is heated and airtight, micro-organisms break down the biomass at a temperature of between 35°C and 55°C.

How does a biogas plant work?

The principle is quite simple. Biogas is produced in a digester and is then converted into electrical energy and heat in a CHP unit. Our latest development allows refined raw biogas to be fed into the local gas net. The fermented residue can be utilised as a valuable fertiliser. The energy produced represents an important contribution to active environmental protection because it is made out of renewable materials.


Ten good reasons to choose biogas

  1. Biogas means independence from oil and gas imports.
  2. Biogas plants generate thermal as well as electrical energy.
  3. Biogas plants can heat buildings but also process water.
  4. Rural areas are made more economically viable.
  5. Biogas slurry is a valuable agricultural fertiliser.
  6. Biogas slurry can be a substitute for mineral fertilisers, and protects drinking water.
  7. Biogas slurry has a high level of plant availability and can even be used as a top dressing.
  8. Biogas is eco-friendly, economical and dependable.
  9. Energy is generated instead of simply throwing away organic residues.
  10. The fermentation process reduces weed seeds’ ability to germinate.
