Stora Enso to establish a joint pulp mill biorefinery research and development project with Metso and Domtar

Stora Enso has signed a research and development cooperation agreement with     
Metso and Domtar to establish a consortium to develop a pulp mill biorefinery.  

The project, based on the latest pulping technology, aims to develop a pulp     
production process with enhanced sustainability and cost efficiency, as well as 
lower investment costs.                                                         

“We see promising opportunities for a breakthrough in sustainable chemical      
pulping technology. The new major innovations will give stronger fibre and      
improve the pulping yield. The innovations will also enable malodorous gases to 
be eliminated and increase the energy efficiency of the pulp production         
process,” says Jukka Kilpeläinen, Senior Vice President, Group R&D.
