Sojitz to Begin “Pool Project Kawasaki,” a Verification Test Project for Efficient Collection and Recycling of Plastic Container Waste from Condominiums in Kawasaki City
– Striving to Realize a More Advanced Resource Recycling System through Horizontal Recycling –
Feb. 8, 2022
Sojitz Corporation (“Sojitz”) has partnered with Enevo Japan KK (“Enevo”), Kao Corporation (“Kao”), Toppan Inc. (“Toppan”), and Recotech Inc. (“Recotech”) to begin “Pool Project Kawasaki,” a verification test project for realizing efficient collection and horizontal recycling*¹of used plastic containers collected as household waste from condominiums in Kawasaki.
In June 2021, the Japanese government announced its “Bill for the Act on Promotion of Resource Circulation for Plastics,” which is planned to go into effect from April 2022. Based on this law, Japan’s plastic manufacturers, retailers, and other business providers (“plastic manufacturers”) are expected to accelerate efforts for separated collection and recycling of used plastic containers generated as household waste.
However, the following issues remain a problem for the separation, collection, and recycling of used plastic containers generated as household waste.
1. High costs to achieve separated collection and recycling
2. Insufficient collection volumes due to difficulties increasing collection rates
In order to accelerate separated collection and recycling of plastics moving forward, Japan urgently needs to build a separated collection and recycling system at a sustainable cost that can ensure a stable volume of plastics for remanufacturing.
The purpose of this project is to create this type of highly advanced resource recycling system in which plastic containers disposed of as household waste can then be remanufactured. Looking towards further expansion of these recycling initiatives after FY2022, Sojitz and its partners will perform verification tests in the following areas.
1．Verify effectiveness of collection proximal to sources of waste production
For this project, plastic waste from households will be collected by installing collection boxes for three separate types of plastics (refill packs, plastic packaging from snack foods and vegetables, and plastic bottles) at multiple condominiums to monitor collection rates and collection status.
2．Verify feasibility of horizontal recycling for each type of collected plastic
Verification of horizontal recycling for refill packs of household and personal care products will be handled by Kao, snack and vegetable plastic packaging by Toppan, and plastic bottles by Sojitz. All partners will work to identify horizontal recycling-related issues and solutions.
3．Verify use of IoT devices and delivery logistics to improve efficiency of plastic transportation and collection
Recotech’s circular renewables platform “POOL”*²and Enevo’s sensor device*³ will be utilized to visualize the amount of plastic collected in the project’s recycling boxes in real time. Sojitz and partners will investigate the feasibility of efficient collection and transport using delivery logistics.
●Period: November 22, 2021 – March 18, 2022 (planned)
Phase 1: Collection and survey
Phase 2: Transport, sorting, and recycling of each type of collected plastic
●Location: Mayfair Parks Mizonokuchi (Takatsu-ku, Kawasaki), Sojitz Musashi-Kosugi Employee Housing (Nakahara-ku, Kawasaki), Sojitz Yurigaoka Employee Housing (Asao-ku, Kawasaki)

Based on the results of this verification project after FY2022, Sojitz and its project partners will expand the scale of the project together with Kawasaki City and other local governments. Sojitz and partners aim to create a separated collection and recycling platform accessible to many manufacturers, which will further expedite progress towards realizing a system that ensures sufficient quantities of plastic for remanufacturing at a sustainable cost.
Through this project and other recycling business, Sojitz will build on and expand its low-carbon and decarbonized businesses to contribute to a decarbonized and sustainable society.
*1: Horizontal recycling: Used products are collected and recycled back to create the same original product.
*2: Circular renewables platform “POOL”: A digital platform developed by Recotech to visualize and centralize management of information such as quality, cost, procurement volumes, and traceability necessary for recycling plastics and other renewable resources.
*3: Enevo sensor device: Collection boxes will be equipped with an ultrasonic sensor that will allow collected volumes to be visualized and confirmed remotely, making it possible to optimize the timing of collection.
