(PRESS RELEASE) GRAZ, 23-Mar-2024 — /EuropaWire/ — 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.

Tobias Osterwalder, Bereichsleiter Weiterverarbeitung, Lignatherm AG, says: “’We are looking forward to offering insulation based entirely on natural building materials that bind CO2. 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.
