Honkajoki biogas plant

The Honkajoki biogas plant currently processes food industry side streams as well as separately collected and packaged biowaste. The plant has its own pre-processing lines for separately collected and packaged biowaste where packaging materials and biodegradable fractions of the feedstocks are separated. Packaging materials are delivered for energy use and biodegradable fractions are used in the biogas process.

Biogas from the plant is sold for use in the boiler and CHP engine of an energy company located nearby for electricity, heat and process steam production. The sanitized digestate generated at the plant as well as the solid digestate obtained from the centrifuges is used as a fertilizer product in agriculture. Reject water from the centrifuges is recycled in the process as dilution water to reduce raw water consumption.

Honkajoki 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 >
