TOKYO, July 31, 2025 - (JCN Newswire) - TANAKA PRECIOUS METAL GROUP Co., Ltd. (Headquarters: Chuo-ku, Tokyo; Group CEO: Koichiro Tanaka) has decided to enter into a business partnership with JEPLAN, INC. (Headquarters: Kawasaki City, Kanagawa; Representative Director, President, and Chief Executive Officer: Masaki Takao; hereinafter “JEPLAN”) to reduce CO₂ emissions and promote the recycling organic materials in the precious metal recovery processes of TANAKA PRECIOUS METAL TECHNOLOGIES Co., Ltd., a company engaged in precious metals business.

This initiative represents a collaboration between TANAKA, committed to advancing a circular economy in the precious metals field, and JEPLAN, which has been pursuing similar goals in the plastics field, with both companies aiming to achieve a decarbonized, circular society.

TANAKA’s Initiatives Thus Far for Realizing a Circular Society

Since its founding in 1885, TANAKA has been a leader in the precious metals industry, actively engaged in recycling these limited and valuable resources. Among the process waste materials received from customers who request recycling, those containing organic materials (plastics) as main components with precious metals attached or adsorbed have traditionally been processed through incineration to remove the organic materials, with precious metals then recovered from the ash left behind.

While this incineration process has addressed the removal of environmentally regulated substances, the reduction of CO₂ generated during the combustion of organic materials has become a major challenge in realizing a decarbonized society.

Transforming the Precious Metal Recovery Process Through a Business Partnership with JEPLAN

JEPLAN has established proprietary chemical recycling technology for polyethylene terephthalate, a type of plastic. To address the aforementioned CO₂ emissions issue, TANAKA is considering using chemical recycling in the future, in addition to the conventional precious metal recovery process through incineration. This initiative is being explored through a business partnership with JEPLAN. The materials targeted for chemical processing include plastics such as syringes and wiping cloths. CO₂ emissions from the targeted precious metal recovery process are expected to be reduced to approximately 10% of conventional levels.

In addition, this process enables not only precious metal recovery, but also plastic regeneration, with TANAKA and JEPLAN each contributing to the realization of a decarbonized, circular society through their respective areas of expertise.
