Circular economy is seen as a necessity in supporting climate change mitigation, resource efficiency and sustainable growth. Biogas production represents a model example of the circular economy

Biogas is sustainable

Biogas is a completely renewable fuel produced from agricultural, industrial and household waste and residues. In the biogas production process, the biodegradable feedstocks are converted into energy and recycled nutrients by anaerobic microbes that feed on the biomass. The biogas can be used locally as such, or upgraded to biomethane and further liquefied, which enables the transport of the gas over longer distances. Renewable biogas can be used as a fuel for cars, buses, heavy-duty vehicles and maritime transport, as well as in industry and energy production.

We promote circular economy together with partners

Gasum collaborates with partners across the value chain to promote the circular economy.

We strive actively to increase biogas production capacity

Gasum has prepared for the growth in gas demand by investing purposefully in the development of the Nordic gas infrastructure. We strive actively to increase biogas production capacity by building new biogas plants, increasing the performance of the existing ones and by procuring biogas from partners. By 2025, we will make 4 TWh of biogas available through our own production and through certified European partners.

We are a major processor of biodegradable fractions of waste generated in society

We process biomass from agricultural side streams, crops, manure, inedible food waste from retail outlets, food industry side streams, spoilt batches, and sewage and grease trap sludge.

Our waste processing service enables the re-use of biodegradable waste material as energy, thereby reducing the energy lost in processes such as waste combustion or composting. Our network of fairly large biogas plants improves economy of scale and efficiency and allows biomass processing to be optimized between plants depending on, for example, logistics, capacity, market conditions and different feedstock fractions.

Besides biogas, our plants produce various recycled nutrients

Nutrient residues such as nitrogen and phosphorus arising as a by-product in biogas production can be returned to the food chain as fertilizers or refined for industrial purposes to replace mineral and fossil nutrients and fertilizers. Gasum's fertilizers are produced in compliance with fertilizer product legislation, and the operations are supervised by Finnish and Swedish authorities.
