Biogas – energy source for today and increasingly for the future

Modern technologies take advantage of the fermentation process in natural and organic substances: biogas. To generate biogas energy using a fuel that is both efficient and environmentally friendly.

The mixture of methane gas and carbon dioxide offers a clean alternative to fossil fuels. Our gas treatment and flaring systems are designed both for fermentation plants for biomass and for plants for fermentation of sewage sludge. With both processes, the ultimate aim is the generation of "green" energy.
