The Japan Chemical Industry Association (JCIA) has decided this year“s winners of the JCIA Technology Awards. The Grand Prize, which recognizes achievement with high industrial value, has been awarded to Asahi Glass for its “development and commercialization of GI-type all-fluoroplastic optical fibre” and Mitsui Chemicals for its “commercialization of gas-phase process for production of L-LDPE using a metallocene catalyst.” The former uses amorphous fluororesin as the core material for optical fibres, and was recognized for its high bandwidth and longer transmission distance compared to conventional plastic optical fibre. The later makes it possible to manufacture high-strength L-LDPE, from which thinner films can be produced, using an inhouse-develped two-stage polymerization process and a metallocene catalyst suited to the gas phase process. The Award for Technical Excellence, which is awarded for relatively small-scale but original technology, was awarded to Dainippon Ink and Chemicals for its “development of VOC-free printing ink (planographic ink).” The VOC contained in planographic ink was effectively reduced to zero while improving ink performance. The Environmental Technology Award was presented to Mitsubishi Chemical for its “development and commercialization of new diphenyl carbonate manufacturing process,” which effectively uses and recovers byproduct hydrochloric acid without using NaOH, and which has a low energy load, with a phosgene conversion rate of close to 100%.
