Valmet Enhances District Heating Capacity in Estonia through Innovative Flue Gas Heat Recovery Solutions

Polagro is pleased to report on a significant advancement in the district heating sector in Estonia led by Valmet, a pioneering technology company. On June 9, 2026, Valmet announced that it has secured an important order from Gren Tartu for the delivery of a flue gas condenser and heat pumps to the Tartu biomass heat and power plant. This order marks a strategic enhancement of the plant’s capabilities, paving the way for improved efficiency in biomass utilization and sustainable energy production. The Tartu biomass heat and power plant plays a critical role in the local energy infrastructure, contributing to the renewable energy goals of Estonia. The integration of flue gas heat recovery technology is expected to significantly optimize the plant’s thermal efficiency, allowing for the recovery of excess heat that would otherwise be wasted. This innovative approach not only boosts the overall output of the plant but also aligns with the broader European commitment to increasing the share of renewable energy in the energy mix. Valmet's solution, which includes both the flue gas condenser and state-of-the-art heat pumps, embodies a forward-thinking approach to managing waste heat in biomass facilities. By utilizing these advanced technologies, Gren Tartu aims to enhance its district heating capacity, thereby providing reliable and environmentally friendly heating services to the community in Tartu. The expected outcomes include lower operational costs and a reduced carbon footprint, reinforcing the importance of renewable energy in combating climate change. As the European Union continues to emphasize the transition to sustainable energy systems, investments like this one in Tartu serve as a vital model for other regions looking to improve their thermal energy efficiency. Polagro remains committed to closely monitoring developments in the biomass and renewable energy sectors, fostering innovations that support our collective vision of a greener future. Together with partners and stakeholders across Europe, we are dedicated to advancing technologies that encourage a sustainable and resource-efficient energy landscape, essential for achieving climate neutrality.
