Dec. 9th,2022 Conference of SPE Japan section “Aiming for Eco-Friendly Plastic -Resource Circulation and Recycle-”

“Aiming for Eco-Friendly Plastic -Resource Circulation and Recycle”

Plastic is lightweight, durable, and easy to mold. It is one of the materials that are indispensable in human life, and is used for various products, containers and packaging.  On the other hand, in recent years, there is a need to respond to marine plastic litter issues, climate change issues, and stricter regulations on waste imports in other countries, and the importance of resource circulation and recycling of plastics is increasing.

In this lecture, the main theme is “Aiming for Eco-Friendly Plastics – Resource Circulation and Recycle -“, and lectures will be given by four lecturers who are active on the front lines from the basics to applications and practices.

Opening remarks by Hiroshi Ito, the organizer, SPE Japan Section Chief, and Professor at Yamagata University



“Possibility of plastic recycling and integration of arterial/venous industries towards carbon neutrality”

Professor Toshiaki Yoshioka, Graduate School of Environmental Studies, Tohoku University

Abstract: Efforts to realize a carbon-neutral society and establish a circular economy are becoming indispensable. Plastic recycling is positioned as a symbol of these issues. In this lecture, I would like to introduce the ideas and technical possibilities for solving these issues through the integration of arterial and venous industries.



“Eliminating the Idea of Waste”

Mr. Eric Kawabata, APAC General Manager of TerraCycle Japan

Abstract: In Japan, 9.4 million tons of plastic are disposed of annually. Per capita, this figure is 37 kg, said to be the second highest in the world. The world is urgently addressing the problem of single-use plastics.  At TerraCycle, our mission is Eliminating the Idea of Waste®. Businesses, government entities, and people like you work with us globally to keep trash out of landfills or from incineration.  In this lecture, through collaboration and innovation,we will introduce the world’s first solution development in all fields from recycling to reuse.


15:05-15:15  Break Time



“Demonstrative operation for chemical recycle of polystyrene”

Masafumi Kobayashi, Managing Director of PS Japan Corporation

Abstract: PS Japan Corporation has been developing chemical recycling technology from polystyrene resin to styrene monomer by pyrolysis aiming at constructing commercial scale plant We are now constructing our demonstrative plant and willing to start it from spring 2023. In this lecture, I will give an outline of PS resin situation in Japan and introduce our chemical recycle technology.



“Possibility of Chemical Recycling of Plastics by Biotechnology “

Satoshi, Koma, General Manager of Sekisui Chemical Co., Ltd.

Abstract: Polymerization technology and molding technology have evolved, and plastics have made our lives richer and more comfortable. But, Plastics recycling is becoming difficult due to the use of complex molecular structures and composite molded products. In this lecture, as one of the solutions, I will outline a new chemical recycling technology that combines plastic synthesis gasification and microbial gas fermentation.
