Bio natural gas is made from biogas, which itself comes from the fermentation of organic material. The preferred types of plants are those specially bred and planted for energy purposes. Plants used have been bred naturally without any genetic engineering.

Bio Natural Gas - New Energy from Biomass

The harvested plants are chaffed and cast into the fermenter, the core of the biogas plant, where they are fermented under airtight conditions. Biogas is created during this process. It is made up mainly of methane (50-70%) and carbon dioxide (30-50%). Minor components are nitrogen, oxygen and sulphur.

Processing Biogas to Bio Natural Gas

In the next step the biogas is dehydrated, carbon dioxide and sulphur components are removed for the most part from the biogas in a gas treatment plant. In further innovative steps biogas is processed to bio natural gas, which has equivalent properties to natural gas.


In order to feed the bio natural gas into the natural gas pipeline system, it has to be compressed to the operating pressure of the network. The product can then be transported in a way which is environmentally-friendly. What's more, it can be stored if required and is ready for use anywhere, regardless of production location. 


Important for environmental protection: Fermentation byproducts caused during the production of bio natural gas are a valuable fertilizer and are returned to the fields. This cycle makes it possible for energy crop agriculture to do without additional fertilizers.
