Sojitz Corporation (“Sojitz”) in consultation with Sojitz Pla-Net Corporation (“Sojitz Pla-Net”), has concluded a subcontracting agreement along with M.M.Plastic, Inc. (“M.M.Plastic”), Kao Corporation (“Kao”), Toshi Kankyo Engineering Co., Ltd. (“Toshi Kankyo Engineering”), and RECOTECH. K. K. (“RECOTECH”) for a low-carbon material recycling model study (“this Study”) with Kawasaki City, Kanagawa Prefecture, to realize an urban circular economy. Kawasaki City is a subsidy recipient under a business subsidy program to curtail CO2 emissions put forth by Japan’s Ministry of the Environment in 2020 as part of its efforts to establish Regional Circular and Ecological Spheres (Regional CES) through innovation for decarbonization.

This Study aims to recycle resources to contribute to the realization of the "Kawasaki Eco₋Town Plan," * 1 which strives to create a sustainable society in which the environment and industrial activities are in harmony. In order to realize the necessary recycling of resources in the region, a cost-effective waste plastic recycling system will be constructed to reduce CO2 emissions. Additionally, through operation of this recycling system, this Study will demonstrate the effects of low carbon.

The target businesses in this Study are shopping centers and other commercial businesses that produce plastic waste. For plastics, there are challenges to more appropriate industrial waste treatment, and it is often difficult to achieve cost benefits from recycling. Most plastic waste is incinerated as general waste or is not used effectively, which is a leading cause of rising CO2 emissions. In order to provide a solution, we will work with companies that promote use of recycled materials to analyze reusable plastics and match plastic waste suppliers and potential users. At the same time, verifications for sustainable recycling will be performed using Material Pool System (MPS)*² to visualize the amount of reusable resources, consolidate the collection of similar materials, and verify optimal collection routes. This Study will be in collaboration with businesses located in Kawasaki City that produce plastic waste, including Marui Group Co., LTD. (Marui Family Mizonokuchi) and Mizonokuchi Shintoshi Co., Ltd. (Nocty Plaza).

Sojitz Group’s Key Sustainability Issues state the company’s goal to contribute to the global environment through our business and to pursue the development, supply, and use of sustainable resources. This project with Kawasaki City will not only promote decarbonization through sustainable use of the region’s resources, but also serve as a business model that can be widely expanded to other regions as an environmental solution.


[Role of Each Company and Overview of This Study]

*1: Kawasaki Eco-Town Plan: In 1997, Kawasaki City drew up the Kawasaki Eco-Town Plan targeting the entire coastal area of Kawasaki (approximately 2,800 hectares). Recognized as the first eco-town in Japan by the Japanese government, Kawasaki Eco-Town is revitalizing the city’s industry while promoting the recycling of resources both in Japan and abroad.
*2: Material Pool System (MPS): A system developed by RECOTECH for visualizing the type, amount, and location of waste products. The system plots information on a map based on waste product information input from sources using weighing devices and a dedicated app.
