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