Biogas from the plant is used to generate electricity and heat with the plant's own CHP engines. Heat is used in the plant's own process and also sold to a nearby greenhouse.
All sanitized digestate at the Vehmaa plant undergoes centrifugation. Solid digestate is used in agriculture as a fertilizer product. The evaporator treatment of reject water at the plant is a unique solution in Finland.
In the evaporator, water and concentrated nutrients are separated from reject water. The water undergoes reverse osmosis and, having been fully purified, is then discharged into a local river. Nutrient concentrates are used as fertilizers in agriculture and as wastewater treatment plant nutrients in pulp industry.
The Vehmaa biogas plant is certified in accordance with ISO 9001, ISO 14001, ISO 45001 and ISO 50001 requirements. Compliance with quality, environment, occupational health and safety, and energy management standards will improve Gasum’s competitiveness and also benefit customers. Read more >
