Maximilian Heindl, development chief at Progroup AG. The production line comprises a BlueLine stock preparation system with a new IntensaDrum Duo drum pulper, capable of processing almost 3,000 tons of recovered paper a day. The XcelLine paper machine has a wire width of ten metres and an operating speed of 1,600 m/min. The TwinDrive double unwinder was also included in the scope of supply and increases winder capacity by up to 20 per cent enabling automated full reel changes. It is complemented by a VariFlex Performance high-performance winder. “By deploying extra personnel and working additional day and night shifts, we were able to

accelerate the work in such a way as to enable us to meet the commissioning date,” says René


Bauer, project manager at Voith. Other key innovations include a closed water loop that Voith developed in collaboration with Progroup. In this system, all water used in the paper production process is cleaned in the company’s own water treatment facility using anaerobic and aerobic biological treatments and is then returned to the production process in a resource-conserving manner. “Thanks to the integrated


water treatment plant, we save about 3.75 million litres of fresh water annually. This is equivalent to the water consumption of more than 80,000 people,” said Heindl. “The Eco-Management and Audit Scheme certification of the European Union verifies the sustainability of our facility.” Progroup is additionally
