To markedly reduce their climate footprint and pollution, large apparel and furniture brands are in dire need of affordable greener alternatives to cotton, traditional viscose and polyester. Several Nordic pulp makers are part of projects developing new clean ways https://www.reuters.com/article/us-nordics-forestry-idCAKCN0WF076 to turn trees into textile fibre.

TreeToTextile said in a statement its plant would have a production capacity of 1,500 tonnes and its owners would fund the bulk of the 35 million euro ($42.6 million) investment.

"The novel process is deliberately designed to have low energy demand and low chemical need. It is engineered to suit large scale production and includes a recovery systemfor reusing chemicals," it said.

"By investing in a demonstration plant, we are finally on the go. With it we are turning years of R&D into reality to increase the biobased share on the textile market to support climate action."

TreeToTextile, whose fourth part-owner is innovator Lars Stigsson, said the plant would be located at Stora Enso's Nymolla mill in Sweden, and its construction would start in the near future.

Viscose is the main existing textile fibre from wood pulp - followed by the newer lyocell which has a cleaner manufacturing method. Production is dominated by Austria's Lenzing, India's Aditya Birla and China's Sateri.
