On 17 November 2025, the webinar “Waste Utilisation in Heating: Innovative Technologies from Central Europe” brought together companies developing cutting-edge solutions for decarbonising heating systems. The webinar was organised jointly by REHEATEAST, GreetGeo, GreetCE and HEAT35.
The event highlighted how practical technologies are already reshaping energy systems across Central Europe. Moderated by Krisztina Dély, the session featured Pál Kiss (THERMOWATT), Balázs Hepp (e-Chemicals) and Szilveszter Sztruhala (HeatVentors), each presenting approaches that recover unused energy, convert industrial emissions into valuable resources, or store heat more efficiently. Participants learned how wastewater can serve as a stable renewable heat source for district heating using advanced heat-pump systems, with several successful installations already in operation and AI-based mapping tools helping cities identify their untapped potential.
The discussion also explored how electrochemical technology can turn captured CO₂ into carbon monoxide using renewable electricity, offering a flexible, low-emission feedstock solution for the chemical and metallurgical industries. Meanwhile, intelligent thermal batteries based on phase-change materials demonstrated how compact, low-loss heat storage can support district heating networks, reduce peak loads, and increase renewable integration.
Together, the solutions presented by Kiss, Hepp and Sztruhala illustrated the breadth of innovation emerging in Central Europe’s clean-heating landscape. By recovering energy already present in urban systems, transforming emissions into useful products, and storing heat more intelligently, the technologies showcased during the webinar offer scalable tools to help municipalities, utilities and industries move toward a more resilient, low-carbon future.
