R&D and Sustainable Production in the Pulp and Paper Industry – Some examples

Professor Gunnar Svedberg, INNVENTIA

Sustainable Development: A Challenge for European Research

Brussels, May 26, 2009

Sustainable Development Conference May 26, 20092

INNVENTIA (new name for STFI-Packforsk) – a Research Institute covering three value chains- printing and media- packaging and the supply chain- bioenergy, chemicals and biomaterials

The INNVENTIA Group 270 employees turnover of 30 Million € Industry-owned by 71%

Important energy achievements in the Swedish pulp and paper industry during the last decades

• Oil consumption reduced by almost 80% since beginning of the 1970s while production has doubled

• Use of biomass for energy purposes almost doubled

• Energy efficiency increased

Main reasons for changes:- Increasing oil prize- Environmental restrictions

Important environmental achievements in the Swedish pulp and paper industry during the last decades

• Emissions of sulphur compounds has declined by over 95% since the beginning of the 1980s

•Emissions of dissolved organic substances (COD) have been reduced by over 85%

• Emissions of chlorinated organic compounds (AOX) have decreased by over 95%

New and innovative processes for radical changes in the European pulp and paper industryIntegrated Project (IP) in FP6(2004-2008)

Coordinator: INNVENTIA, Catharina Ottestam Total budget: 17,9 Million € EU contribution: 10,0 Million € 26 partners (institutes, universities,

suppliers, papermakers)

9 countries involved(Sweden, Finland, Germany,

France, Switzerland,

Netherlands, Austria,

Spain, Greece)


- The challenge:

More from Less!

Energy-30 %

Wood Raw Material-30 %

Waste & Emissions-20 %

ECOTARGET

Water-20 %


+ Product properties

+ Reduced use of raw material

+ Reduced energy consumption
