Production methods

Production methods

Biogas is produced naturally by the biological breakdown of organic matter in absence of oxygen, i.e. anaerobic digestion or fermentation. Raw materials for production of biogas are biodegradable materials such as biomass, manure, sewage, municipal waste and energy crops.

Production of biogas utilizing anaerobic digesters

The process is taking place within an air-tight tank fed with biodegradable materials. During the process methane gas is produced and collected at the top of the digester. The methane gas produced is a renewable energy source and is called biogas, which can be used for heating, electricity or purified to a higher content of methane and used as a vehicle fuel.

The Baltic Biogas Bus project is supported by the EU, is part of the Baltic Sea Region programme and include cities, counties and companies within the entire Baltic region.
