Rewarded for new paradigm in pulping technology

​The Arne Asplund Mechanical Pulping Award 2018 has been granted to Professor Anders Karlström, Head of the department Electrical Engineering at Chalmers.
​The award is given out every two years by Arne Asplund Mechanical Pulping Award Foundation to promote the development of new technology for the manufacture of high-yield pulp. It is awarded in recognition of outstanding achievement in research and development of mechanical pulping technology.

“To receive this award is a great honor for me”, Anders Karlström says. “I have been working with this for many years and it feels fantastic to get a confirmation that the struggle really has been worthwhile.”

The justification for the award reads as follows: “Based on his deep understanding of the fundamentals of refining in mechanical and chemimechanical pulping, Anders Karlström has initiated a paradigm shift regarding the theory of refining by introducing the entropy model. This new approach offers tools to understand the interplay in the refining zone with regards to refiner operation, plate patterns and the produced pulp quality. These new findings are already in use in several production lines offering a set of possible ways to optimise quality and specific energy input.”

The award consists of a gold medal and an honorarium of SEK 25,000. The prize ceremony will take place at the International Mechanical Pulping Conference, IMPC, in Trondheim on 29 May.

Regarded as the "Nobel Prize" in the field of mechanical pulping, the Arne Asplund Mechanical Pulping Award was established in 1985 to commemorate the Swedish engineer Arne Asplund’s contribution to the pulp and paper industry worldwide. He was the inventor of the thermomechanical pulping technique, known as the defibrator-method, also called the Asplund-method, for pulping wooden chips.
