Energy source for today and increasingly for the future

Efficient and environmentally friendly biogas

Modern technologies take advantage of the fermentation process in natural and organic substances: biogas. Generating biogas energy with 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 for both fermentation plants for biomass and for plants for fermentation of sewage sludge. With both processes, the ultimate aim is the generation of "green" energy. 

Our biogas products

IFL1C | Standard gas flare for gasholder operation
