Paper making without water

4

Technology Description

70% of the energy need for paper-making is the use of heat for drying. When water could be eliminated there is no need for drying. The challenge is to obtain inter-fibre bonding and also dry defibration of pulp or paper for recycling without damaging the fibre. This is challenging, firstly, as paper owes its strength to hydrogen bonds that are formed during the removal of water, and secondly, as during repulping of dry pulp or paper for recycling the hydrogen bonds are normally mildly broken upon the addition of water.

Relevance for Net Zero

Huge abatement potential.
