Wood2Biogas

We are developing technology to improve the energy production of the biogas plant. The project develops and demonstrates the gasification of wood and the use of wood gas as raw material for biogas alongside manure, grass feed and biowaste. This makes it possible to improve the biomethane production of the biogas plant without creating more digestion residues. In addition, we are developing the production of biochar alongside the wood gasification process. The project will create a sustainable and economically viable new overall concept.

Wood2Biogas project combines a gasification technology and a traditional anaerobic biogas process. Technology development aims to produce and use the gasification gas to boost methane formation in the biogas process, and simultaneously produce biochar. This enables the use of woody materials in biogas energy production without increasing the amount of digestate from the biogas process. This also has a positive effect on the thermal economy of the biogas plant.

Alongside the technology development work of the innovation group, the Wood2Biogas project is developing agri symbiosis through cooperation and communication, where bioeconomy entrepreneurs and rural actors can gain synergies for their activities. In addition to biomethane, thermal energy, fertilizers and soil improvers, the product range includes biochar generated during the gasification process. These products that meet the sustainability criteria are usable for different actors to achieve carbon neutrality.

The Wood2Biogas concept enables the production of biomethane from forest residues and waste wood, providing a cost-effective way to increase the productivity of traditional biogas plant. The project enables the use of the same equipment for the simultaneous production of biochar and product gas in an energy-efficient process, making the production of carbon-negative energy a reality.

Target Group

Owners of biogas plants and operators aiming to invest in biogas plants in Finland and export markets.

Operating Region

In the implementation phase, the operating region is Varsinais-Suomi, Pirkanmaa, Uusimaa and Kanta-Häme. However, the field of operation of the concept to be developed in the project is widely located throughout Finland, so the expansion of the region of operation as the project progresses is a natural goal. The concept, designed as an international one, expands the scope even further.
