(1) 海洋プラスチック・マイクロプラスチック問題の解決に向けて―国際標準化動向，日本の施策―

抄録

Marine pollutions by plastics litter and microplastics are big environmental problems which shall be solved Internationally. To solve these problems, 3R（reuse, reduce, and recycle）are most important issues, innovations for biodegradable and/or biobased plastics（bioplastics）are also important. Evaluations for biodegradable or bio-based plastics should be based on International standards such as ISO standards which were discussed in ISO Subcommittee SC14“Environmental aspects”of Technical committee TC61“Plastics”. Marine biodegradation evaluation methods are defined by ISO methods. New functional plastics with good biodegradability in marine will be evaluated by ISO method and market introduction will be promoted by certification of requirements defined in ISO. Japanese government had been determined some measures to promote bioplastics. For example, market introduction of 2 million tons of bioplastics in 13 million tons of total plastics is the challenging target in 2030 determined in the strategy for plastics from sustainable resources （2019）. Many budgets by Japanese government, support for innovation and market introduction of bioplastics.
