20221021 Conference of SPE Japan section

“Polymers Degrading in the Ocean”

 The marine plastic pollution is attracting attention as a kind of environmental problem. To solve this global issue, various research and development efforts are conducted.

While the bio-based marine degradable polymer materials is one solution, the durability required from a practical standpoint is expected to be at odds with their degradability in the ocean.

 In this lecture, the purpose is to consider the compatibility between the expression of function and degradation in a short period of time contrasting biodegradable polymers and conventional petroleum-derived polymers.Detailed explanations will be given by professors specializing in various fields from different perspectives. We hope that engineers involved in the fields of material development, plastic molding and processing, and product development will attend this meeting, and that it will provide a good opportunity to deepen mutual exchange.
