What is Biogas?

Biogas consists of approx. 2 / 3 methane (CH4), 1 / 3 of carbon dioxide (CO2), a little hydrogen sulfide (H2S), and a little hydrogen (H2). It is formed by the decomposition of manure and other organic waste, either from industrial or household waste or energy crops such as grain, corn silage etc..
The process takes place in ethical anaerobic environment (anaerobic) in the reactor tanks where the process is controlled toil in terms of temperature, pH, and more.
The reactor is a biological degradation process and the bacteria produce biogas. Biomass resident in the reactor at approx. 2-3 weeks.
Biogas is cleaned of sulfur and sent to a great engine when it is burned down.

Approximately 40% of energy are transformed to elektricity and the rest goes to heat from the engine. This heat is utilized through heat exchangers and sold to Brønderslev Central Heating
You can use a total of about 75% of energy, by:
40% electricity
35% used heat
 The process has a loss of about 25%, which break down roughly as follows:
15% is used for heating of the biomass
10% is loss from heat in the engine.
In principle, all organic material can be converted into biogas.
GFE-Krogenskær uses a combination of the following organic materials:
Pig slurry, solids separated from various types of manure, organic waste from slaughterhouses and various other types of products with high fat content.
The plant is described as a common facility that receives manure from several agricultural and also different types of waste from industrial, etc..
