In 2009, Progroup AG invested in the construction of a new paper mill for corrugated base paper at the Eisenhüttenstadt site in Brandenburg. The paper machine has a stock width of 10.10 m and is designed for a construction speed of 1,900 m/min. The PM hall was designed as a precast reinforced concrete structure and is 380 m long. A 180 t overhead crane transports the produced paper amboure to the winder. The futuristic, 4-storey administration building is attached to the side. SCHUSTER engineering acted here as general construction planner for the entire project.
