Sumitomo Riko, Sumitomo Rubber, and Sumitomo Electricto Collaborate with US Carbon Recycling Firm LanzaTech
to Accelerate Circular Economy:
Joint Venture to Focus on Developing Waste RecyclingSolutions
Sumitomo Riko Co., Ltd. (Headquarters: Nakamura-ku, Nagoya; President & CEO:Kazushi Shimizu) is pleased to announce a collaboration with Sumitomo Rubber
Industries, Ltd. (Head Office: Chuo-ku, Kobe; President & CEO: Satoru Yamamoto)and Sumitomo Electric Industries, Ltd. (Head Office: Chuo-ku, Osaka; President:Osamu Inoue). This initiative is designed to further the development of recycling
technologies, paving the way for a circular economy.
In November 2022, Sumitomo Riko announced a joint development agreement withLanzaTech Global, Inc. ( "LanzaTech″; Nasdaq: LNZA), a US-based carbon recycling
firm known for its expertise in carbon capture and utilization (CCU) technology.
Sumitomo Rubber, along with Sumitomo Electric, will be taking part in this joint
development.
The three companies will join forces with LanzaTech in joint development, aiming topioneer groundbreaking technologies that enable a circular economy, transformingwaste materials, including rubber, resin, urethane, and metal, into valuable
resources.

Tripartite Collaboration

1 / 4

This time around, we are taking another step forward to accomplish a circular
economy for raw materials. Together with Sumitomo Rubber and Sumitomo Electric,
we are pushing ahead with the development of new technologies in collaboration
with LanzaTech. We aim to leverage LanzaTech’s biorecycling technology to turnwaste materials like our products into isoprene, which can be used as new rubbermaterials. This will be achieved by gasifying the waste materials and purifying theresulting gas, and then putting them through a fermentation process thattransforms the gas into new raw materials. Our end goal, working alongside raw
material manufacturers, is to explore the feasibility of establishing a recycling
technology that enables the reuse of isoprene as materials for rubber and resin. We
are also contemplating the idea of recycling the metals recovered during thegasifying process and reusing them as raw materials.

Collaborative R&D framework

We believe that the start of collaboration among the three companies will enable us
to make significant progress toward a recycling-oriented society, since the products
and wastes of the entire group of three companies, including Sumitomo Rubber'stires and Sumitomo Electric's wire harnesses, in addition to Sumitomo Riko'sproducts and wastes, will be covered by this new collaboration. In addition, as we
expand our scale and accelerate our efforts toward a circular economy, we expect tomake progress in collaboration with companies and organizations beyond theboundaries of the three companies, further expanding the circle of recycling.
