Andritz to supply refiner for new Lignatherm AG wood fibre insulation board plant
16 April 2024Andritz has received an order from Lignatherm AG to supply a pressurized refining system for a new wood insulation board production plant in Küssnacht am Rigi, Switzerland.
Lignatherm is a subsidiary of Schilliger Holz AG, a company operating sawmills and wood processing plants at three locations in Switzerland and France.
The greenfield plant will use exclusively wood chips from local forests to produce eco-friendly insulation board.
“’We are looking forward to offering insulation based entirely on natural building materials that bind CO2,” said Tobias Osterwalder, head of processing at Lignatherm AG.
“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 fibre 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.
Andritz has a track record of supplying 16 fibre preparation systems for insulation material production.
