Voith supplies packaging paper machine to Progroup AG

September 1, 2020  By P&PC Staff

German paper manufacturer Progroup AG has successfully commissioned the PM 3, a modern packaging paper machine developed by Voith, at the company’s Sandersdorf-Brehna facility in Saxony-Anhalt.

PM 3 is set to produce 750,000 tons of testliner and corrugated medium annually. A comprehensive sustainability concept ensures the least possible consumption of resources.

Voith delivered the entire production line including a BlueLine stock preparation with the new IntensaDrum Duo drum pulper, which can process almost 3,000 tons of recovered paper a day.


The XcelLine paper machine has a wire width of 10,000 mm and an operating speed of 1,600 m/min. The TwinDrive double unwind, also included, increases winder capacity by up to 20 per cent and allows automated full reel changes.

It is complemented by the VariFlex Performance winder. The scope of supply also includes the process air and hall ventilation systems. Voith also provided a startup clothing package for all sections of the paper machine.

Other key innovations include the 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. This allows a wastewater-free paper production process.

“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,” says Maximilian Heindl, member of the board and chief development officer at Progroup AG.

“The Eco-Management and Audit Scheme (EMAS) certification of the European Union verifies the sustainability of our facility.”

For the new facility, Progroup is additionally investing around €100 million in resource-saving technologies and environmental protection.
