Important results from the project

The project´s objective has been fulfilled through new knowledge about how more efficient washing of paper pulp in the pulping process can reduce water and chemical consumption and improve energy efficiency and pulp quality. The project has also strengthened expertise within the Swedish forest industry through doctoral training and supervision of thesis work, where former students are now working within large Swedish industrial companies.

Expected long term effects

The project is expected to contribute to the development of more resource- and energy-efficient pulp processes through reduced water and chemical consumption, improved pulp quality and process economics. The project has also strengthened the supply of skills and collaboration between academia and industry, creating good conditions for continued research and innovation in sustainable forest-based bioeconomy.

Approach and implementation

The project was implemented as planned within the framework of the Resource Smart Processes Graduate School with a focus on doctoral education, experimental studies and process efficiency linked to pulp washing in the pulping process. The work followed the schedule and included regular meetings and collaboration between academia and industry. The collaboration with industrial partners, who participated through co-supervision, contributed to the relevance and practical anchoring of the project.
