In a unique project, Fortum Nynas AB’s oil refinery in Nynäshamn is supplying processs team from a biofuel-powered combined heat and power plant. In return, Fortum gains access to the surplus heat from the refinery to heat the Municipality of Nynäshamn. Among other things, the project has resulted in a decrease of nearly 100,000 tonnes per year in carbon dioxide emissions in the region.
