Cooperation provides large energy and environmental benefits

"The use of biofuel for a refinery is unique and the cooperation means environmental benefits for us and for the whole society, explains Cyril Thebault", Site Manager at the Nynäshamn refinery.

The new agreement means that a new plant for the purification of process water will be built with several environmental benefits as a result. In addition to energy efficiency improvements equal to half of the city of Nynäshamn's district heating, the consumption of city water also decreases by around 120 000 tonnes per year at the Nynas refinery.

"The new facility is expected to free up about 50% more residual heat than today, which means that we reduce the need for fuel, thus saving the earth's resources", explains Jonas Dyrke, Business Developer at Värmevärden.

The cooperation between Nynas and Värmevärden has been going on since 2004, when a joint project resulted in a modern energy solution with a biofuel-fired heat and power plant for electricity, steam and district heating production, combined with residual heat recovery from the refinery to the district heating network. Värmevärden's power plant in Nynäshamn supplies the Nynas refinery with 160 GWh of steam annually. Residual heat equivalent to 35 GWh is recycled, sufficient energy to heat 1.750 houses per year. The initiative has also resulted in reduced carbon emissions in Nynäshamn by 100 000 tonnes per year.
