1948


Research and start of pulp fluid waste disposal at the Toyobo Inuyama Plant

Pulp operations were started in 1941 with the aim of providing our own pulp, used in the production of rayon, which we have been manufacturing since before WWII. Our pulp business was temporarily suspended due to the war, but was restarted in 1948. As part of our counter-measures against environmental pollution, we focused our attention on the use of yeast to break down and remove polysaccharides found in fluid waste, and started research into cultivating yeast for pulp fluid waste disposal. This was the start of our advancement into the biochemical field.
