News & press


Treklyngen is located at the industrial estate Follum, outside Hønefoss, on the site of the former Follum paper mill. After the closure of the paper mill in 2012, the current owner, Viken Skog SA, has invested in the clearing and clean-up of the industrial areas. The core infrastructure and several buildings have been refurbished in order to facilitate new industrial processes, primarily based on forest and wood based feedstock.

Treklyngen offers a unique location “in the middle of the forest” secures the availability of wood at competitive cost (0 – 25 % reduced feedstock cost). The brown field infrastructure makes Follum attractive and competitive for new industry due to lower capex needs (10 – 50 % reduced CAPEX). The Follum site offers power, heat, steam, storage space, office space, rail tracks for large scale industrial applications.

The management team at Treklyngen facilitates a balanced portfolio of production facilities ensuring that synergies between plants are maintained. Particularly finding solutions where bi-products and residues from one plant can become feedstock for its neighbor. Treklyngen initiates project and offers project development, project management, procurement and logistics solutions. Our local knowledge and industrial experience secures efficient project execution for our partners.

Currently, Treklyngen has the following projects at various stages of development:

Arba Follum AS – the planning, construction and operation of a 200 000 ton/a advanced wood pellet plant based on steam explosion technology. Partners: Arbaflame AS and Statskog SF.

“Norwegian Wood” – a study of the possibility to produce renewable charcoal for Norwegian Si-smelters and biofuel for the aviation / transport sector. Partners: Elkem AS, Avinor AS and Vardar AS

“Cellunolix” – an agreement for the planning, construction and operation of a 50 million liter/a advanced bioethanol for the transport sector. Partner: St1 Norge AS.
