At iggesund Mill large amounts of thermal energy are produced by burning wood-containing liquors.
At the Hallsta and Braviken paper mills surplus heat is recovered from the TMP production process.
Significant quantities are also generated by burning bark. natural gas is used at the mills in
Workington and Madrid.
