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.
