Wastepaper put to use in Ostroleka The Stora Enso mill in Ostroleka, Poland, just underwent a major facelift thanks to the opening of a new paper machine, which will double the mill's capacity to 500,000 tonnes per year. The mill produces recycled lightweight paper for cardboard used in boxes for consumer goods and transport. The Polish market for these products is growing by 5 per cent annually. In preparation for the new machine, which was opened in first half of 2013, a power plant under Stora Enso's management was first set up to secure energy for the whole mill. The power plant runs partly on biofuel, using waste from the forest industry and bark from on-site wood handling equipment.
