Previous experience at the Heinzel Group with successful projects managed by Andritz led to the Austrian group rebuilding the groundwood mill into a complete OCC line at Laakirchen. PPL reports
remembers: “One of the first ideas our chairman, Alfred Heinzel, had was that we would have to improve our results and avoid being affected by the falling demand for printing grades.” Various possibilities were discussed, but it soon became clear that PM10 would be ideal for the production of corrugated base paper. “Market volume was also needed that would match the capacity of the machine. And as a result, corrugated base
paper became our speciality,” said Lunabba.
Good foundations The final decision on the rebuild of PM10 was made in August 2016. It was decided that the machine would now be converted to make 450,000 tons per annum of high- grade fluting and testliner with a grammage of 70-140 g/sqm from 500,000 tons of recycled fibres (RCF). A budget of around €100 million was estimated. The other machine, PM11, was to continue
producing graphic paper grades in a highly-efficient production process. “We didn’t want to run any quality risks,” says Lunabba. “So it was important for us to go with tested and proven solutions. Andritz has a great deal of experience with RCF lines and had also proved that they know how to successfully convert machines. However, Andritz was new to corrugated base paper so we also had to work together closely and help each other in
