... the green energy source of the future
Biogas is produced when bacteria degrade biological material in the absence of oxygen, in a process known as anaerobic digestion. Biogas consists of methane and CO2 and is produced from various processes such as agricultural biodigesters, wastewater treatment and landfills.
The methane part of the biogas, often up to 60 percent, can be used as a substitute for natural gas. In addition to the economic advantage, this also provides an environmental benefit as it eliminates the emission of this greenhouse gas into the atmosphere. The biogas can be used directly for heating purposes or fed to special gas motors for the generation of electricity and heat. These gas motors are specifically designed to handle the low caloric biogas mixture in an energy-efficient way. As a result, the biogas that would otherwise be wasted is now a useful by-product that can significantly improve the economics of a wastewater treatment plant or a landfill.
Green Gas ... sustainable success! For agricultural digesters and companies with an on-site wastewater treatment plant such as breweries or paper producing companies, Norit Haffmans’ solution is excellent for recycling biomass into green gas and CO2. The green gas can be used in their existing gas plants reducing natural gas costs and the CO2 can be sold as an additional benefit.
