Arne Asplund Mechanical Pulping Award 2024 

The Arne Asplund Mechanical Pulping Award 2024 has been granted Professor Thomas Granfeldt. Over the past four decades, Granfeldt has made significant contributions to the field of high-yield pulping research, encompassing both TMP and CTMP processes. However, the primary focus has been on the CTMP process, particularly involving various hardwood species.

The award is endowed every second year by The Arne Asplund Mechanical Pulping Award Foundation to promote the development of new technology for the manufacture of high-yield pulp.

The 2024 laureate

Granfeldt’s understanding of the delicate balance between chemical impregnation of chips, refining strategy and peroxide bleaching has enabled him to demonstrate how to produce hardwood based CTMP for various end-uses at lowest investment and production costs. The combination of impregnation chemistry, chip-refining strategies and peroxide bleaching enables production of high bulk hardwood CTMP while maintaining high brightness. Such pulps are of particular interest in production of multiply paperboard.

A key to success is a profound understanding of the necessity for multistage washing in the CTMP process. He has identified the optimal placement of this technology within the process design to minimize both investment and production costs.

Granfeldt graduated from the Chalmers University of Technology in 1982 as a M.Sc in chemical engineering. After some years of research studies at the university he served at various positions in Sunds Defibrator AB, Metso AB and Valmet AB until the end of 2021. Since 2012 he is adjunct professor at Mid Sweden University.

The Arne Asplund Mechanical Pulping Award Foundation

 
The Arne Asplund Mechanical Pulping Award promotes the development of new technology for the manufacture of high-yield pulp. It is awarded to a person or persons in recognition of outstanding achievement in the research and development of mechanical pulping technology.
 
The Arne Asplund Mechanical Pulping Award Foundation was established in 1985 to commemorate the contributions made by Dr. Arne Asplund to the pulp and paper industry worldwide. The Award was made possible through a donation Valmet made to the foundation in 1985. The Chairman of the Foundation is Professor Göran Bengtsson.
