Dr. Arne Asplund (1903–1993) invented the Defibrator pulping refiner and the defibrator-method (also called Asplund-method) for pulping wooden chips in 1930s. His invention resulted in the company AB Defibrator in Stockholm which was merged with Sunds AB to form Sunds Defibrator in 1979.[1][2]

Asplund was rewarded the Gold medal (Guldmedaljen) of the Royal Swedish Academy of Engineering Sciences (IVA) in 1947 for the invention and his further development of the defibrator-method for pulping wood and other fibre rich materials. He was later rewarded the Great gold medal (Stora guldmedaljen) from IVA in 1969 for his efforts on defibration technology.[3] In 2014 Asplund was inducted to the Paper Industry International Hall of Fame.[4]

The annual Arne Asplund Mechanical Pulping Award, was established in 1985 to commemorate Asplund’s contributions to the pulp and paper industry.[5]
