Collection of Good Practices for Reducing Microplastics

The Ministry of the Environment, Japan has compiled a collection of good practices on Japanese companies' efforts and technologies contributing to the prevention, reduction, and collection of microplastics, in order to disseminate them domestically and internationally.

1. Background and Purpose

At the G20 Osaka Summit held in June 2019, Japan proposed the "Osaka Blue Ocean Vision" which aims to reduce additional pollution by marine plastic litter to zero by 2050. The vision has been shared as a common global vision by many countries and regions. To realize this vision, implementing measures against microplastics is urgently needed.

Technologies to reduce microplastics have not been confirmed worldwide. Under such circumstances, it is important to review Japanese companies' technologies and best practices by integrating approaches to effectively prevent, reduce, and collect microplastics. The best technologies and practices currently available should then be disseminated both domestically and internationally.
