Six months after Roto Frank Austria’s biomass heating plant began production managing director of Roto Austria, Christian Lazarevic, emphasized the importance of the installation during the inauguration ceremony in Kalsdorf.

“The biomass plant represents our technical progress, but also embodies the responsibility we feel towards our environment. The plant plays a crucial role in ensuring reliable power supply to our site and therefore contributes to the reliability that we can offer our customers,” said Lazarevic.

The heating plant boasts an operating output of 4 megawatts and features a 90 kWp photovoltaic installation. This means that the site generates 50 per cent of the power it uses and does not depend on external sources for heating the premises and process water. Using biomass ensures a carbon-neutral heat supply.

CEO Marcus Sander highlighted the significance of the Austria production plant for Roto Frank Window and Door Technology (FTT) during the ceremony. “The Kalsdorf plant has been part of our group for 50 years and it plays an important role in our 18 production sites across the globe,” said Sander.


The biomass heating plant will reduce the carbon dioxide emissions of the Kalsdorf plant by 2,160 tonnes per year. This installation compliments the existing systems for producing power and protecting the environment. Three hydroelectric power plants operated privately by the company, one rooftop photovoltaic installation and one open – space photovoltaic installation. The biomass heating plant in Kalsdorf is the first one of its kind for Roto FTT.

The Austrian Bioenergy Group collaborated as a partner in its construction. Roto FTT boasts many global sales subsidiaries, logistics and distribution centers, alongside its 18 production sites and approx. 4,0 00 employees. It has set itself the objective of enhancing net zero emissions and reliability of power supply of the entire group by installing additional power and heat generation systems using renewable energy sources, among other measures. By doing so, Roto FTT is not only reducing its own carbon footprint, but also that of its customers.
