District heating

From surplus to heating

Our own residual product surplus heat is turned into green district heating in Piteå.

Our entire operation is based on fundamental sustainability thinking, from our raw material which is a residual product from Kraft pulp mills to our own residual product – waste heat – turned into district heating by Piteå Energi.

Our industrial plant is fundamentally energy efficient by design, and the manufacturing process requires both heating and cooling. The cooling which takes place generates hot water, which is used for district heating. Our district heating is used partly in our own plant and also in other major industrial premises in the region through the district heating system.

SunPine supplies around 1,690,000 kWh of district heating annually, which corresponds to 75 villas.
