International technology group Andritz has received an order from Lignatherm AG to supply a pressurized refining system for a new insulation board production plant in Küssnacht am Rigi, Switzerland.
This greenfield plant will use exclusively wood chips from local forests to produce eco-friendly insulation board. 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 Q3 2025.
Lignatherm is a subsidiary of Schilliger Holz AG, a company operating sawmills and wood processing plants at three locations in Switzerland and France.
