ANDRITZ to supply a pressurized refining system for production of sustainable insulation to Switzerland

Tobias Osterwalder, Bereichsleiter Weiterverarbeitung, Lignatherm AG, says: “’We are looking forward to offering insulation based entirely on natural building materials that bind CO_2. This will significantly enhance our product range. Having an experienced partner like ANDRITZ on our side is crucial to making this important project a success.”

The new line, with a capacity of 10 bdmt/h, will comprise a pressurized refining system with a 44-1C(P) single-disc refiner and a pressurized digester with counter flow and steam regulation including a C-feeder at its core. A 14” ANDRITZ plug screw feeder will ensure excellent dewatering leading to improved fiber quality at reduced electrical and thermal energy consumption.

ANDRITZ will also be responsible for supervision of erection, commissioning, and start-up. The new production line is scheduled to commence operations in the third quarter of 2025.

With a track record of supplying 16 fiber preparation systems for insulation material production, this order further strengthens ANDRITZ’s position as a leading supplier to the global insulation board industry.

Lignatherm is a subsidiary of Schilliger Holz AG, a company operating sawmills and wood processing plants at three locations in Switzerland and France. The company’s products primarily serve the construction and packaging industry in Switzerland, France, and Italy.
