Saint-Gobain Finland’s Isover Factory in Forssa Enters a New Era – Biovoima Plays a Key Role in the Transformation

The Isover factory in Forssa, operated by Saint-Gobain Finland, has entered a new era. Biovoima has played a central role in enabling this transformation. Thanks to modernization efforts, the factory has started producing glass wool with the lowest carbon footprint within the entire Saint-Gobain Group. These upgrades support the Group’s goal of achieving net-zero emissions by 2050.

Production Powered Entirely by Fossil-Free Energy

The Forssa factory now operates entirely on renewable energy: 50% of the energy comes from biogas and the rest from electricity produced by hydropower. Since 2010, biogas has been supplied via pipeline from a local biogas plant. Now, the availability of biogas has been further increased with the installation of the BIOadapter pressure reduction station, delivered by Biovoima, which also enables the use of gas transport containers to feed biogas into the production process. Biovoima also supplied these gas transport containers to the Forssa plant.

– “With the installation of three new pressurized biogas tanks and the existing biogas pipeline connection to the local producer, we will soon transition to fully carbon-free energy use,” says Juha Strandberg, Production Manager at ISOVER.

– “Half of our energy comes from biogas and the other half from hydropower – this is a major leap toward more sustainable production.”

– “This milestone strengthens Saint-Gobain’s position as a pioneer in lightweight and sustainable construction and brings us one step closer to achieving our net-zero goal by 2050,” says Olli Nikula, CEO of Saint-Gobain Finland.

1,500 Tons Less CO₂ Emissions Annually

With this investment, the plant’s CO₂ emissions will be reduced by up to 1,500 tons per year. This will decrease the life-cycle carbon footprint of the glass wool products by 30–40%.

The environmental impact of the products will be measured and verified through third-party EPD (Environmental Product Declaration) reports by the end of 2025. Up to 85% of the raw material used for the glass wool produced in Forssa consists of recycled glass, making Saint-Gobain the largest user of recycled glass in Finland.

– “At Biovoima, we are very happy and proud to have contributed to this important project as a provider of technological solutions. The Saint-Gobain Forssa factory is a trailblazer, setting an example for the entire Group and industry on how biogas can be used to significantly reduce emissions and drive industrial transition toward fossil-free production,” says Mikko Bengts, Sales Manager at Biovoima.

– “It has been great to be a partner in Isover’s green transition journey. The Forssa plant has been a pioneer in emissions reduction, having used local biogas from Nevel’s biogas plant in its processes for years. Now the journey culminates as the factory switches to fossil-free fuels,” says Jyrki Eurén, Senior Manager at Nevel Oy.

– “Saint-Gobain sets an example and inspires industrial actors to make environmentally conscious choices. Pirkanmaa Waste Management is honored to be part of enabling Saint-Gobain’s sustainable choices by supplying biomethane to the Forssa plant,” says Elina Tiira, Technical Manager at Pirkanmaan Jätehuolto.
