Rajamäen tehdas

A significant investment in geothermal heating has been made at Porvoo Cathedral. This culturally and historically important site will from now on use geothermal heating. Altia Industrial’s Naturet was selected as the geothermal fluid for the system. Produced at the company’s Rajamäki plant, Naturet is Finland’s leading ethanol-based geothermal fluid.

Altia and its Rajamäki plant are celebrating their 130th anniversary this year. Altia’s story began on 20 August 1888, when a group of engineers decided to establish a yeast plant in Rajamäki. One of the main reasons why Rajamäki was selected as the location for the plant was the plentiful and pure groundwater found in the area. Over 130 years, Altia has evolved from a yeast producer to the leading wine and spirits company in the Nordic countries and a listed company.
