Capital and Business Partnership with Circular Economy Traceability System Developer Circularise B.V.

(Headquarters: The Hague, Netherlands; Representatives: Jordi De Vos and Mesbah Sabur; hereinafter, “Circularise”), which develops a supply chain traceability system for circular economy.
  Going forward, SEKISUI CHEMICAL aims to further promote circular economyand increase the value of products to enhance sustainability by participating in the construction of a digital platform through collaborating with Circularise.


  SEKISUI CHEMICAL Group aims to realize a circular economy in 2050 and create a sustainable society. To achieve this long-term goal, we aim to realize a circular economy through our business by working with the supply chain, minimizing the amount of fossil-derived materials used, and promoting resource recycling. We have also defined resource recycling as one of the important keywords for realizing our long-term vision “Vision 2030,” including current businesses and innovative areas.
On the other hand, our partner, Circularise, has also discovered the social issue of information sharing (management, tracking, and certification) in the supply chain, which is indispensable for the realization of circular economy, and has developed a unique supply chain traceability system that utilizes blockchain and zero-knowledge proof (*1). This system enables the management, tracking, and certification of environment-related information such as raw materials, recycling history, mass balance, carbon footprint, and third-party certifications on a highly reliable platform, while also ensuring the concealment of confidential information.
