Pulping properties of hardwoods and softwood

 

Wood pulp made from hardwood and softwood trees has different attributes. In Europe, hardwoods account for 29% and softwoods 71% of wood consumption. 

 

  Hardwood Trees
Softwood Trees
Type of tree
Oaks, beeches, poplars, birches and eucalyptus Mainly pine and spruce
Usage In Europe it is mostly birches (found in Sweden, Norway, the UK and Spain) and eucalyptus (found in Portugal, Spain and Norway) that are used for papermaking. In Europe pine is found in the UK, Norway, Finland, France, Spain, Portugal and Greece. Spruce is found in the UK, Finland, Norway and Sweden.
Type of fibre Short

Long

Average length of fibres 1mm 3mm
Features Achieving bulk, smoothness, opacity Providing additional strength. Also suitable for writing and printing
Typical Products Writing papers, printing papers, tissue papers

Shipping containers, grocery bags, corrugated boxes

 

 

Hardwood and softwood fibres can be blended into a single paper, to achieve a desired combination of strength, whiteness, writing surface or other required characteristics.

The mixed characteristics of recovered fibres makes them particularly suited to applications such as newsprint and increasingly, packaging. Many different types of paper are included in recovered paper.

Two Team Project meeting

Chaired by VDP Vice President Dr. Hartmut Wurster, also Chairman of the INFOR Research Council, representatives of CEPI, PTS, university institutes, BASF and VDP will discuss innovative ways for the paper industry in a carbon-reduced economy.

Attendees will also be the members of the CEPI TWO TEAM PROJECT. Their task is to accelerate the development of breakthrough technologies and processes for the manufacturing of paper. By this the paper industry wants to meet the plans of the European Commission, to reduce CO2 emissions in the EU till 2050 by 80% compared to 1990 and simultaneously increase value creation by 50%.
 

Information about the agenda and the registration link can be found in the invitation.
