Marubeni, together with Circularise B.V. of the Netherlands (hereinafter, “Circularise”), will exhibit a traceability management platform utilizing blockchain technology (hereinafter, “the platform”) at the “2nd CIRCULAR ECONOMY EXPO” (hereinafter, “the exhibition”).

The platform enables the creation of Digital Product Passports*1 (hereinafter, “DPP”), which are under consideration for adoption in Europe, as well as the use of “Smart Questioning” technology*2 and the creation of ledgers and reports using the mass balance approach*3. Marubeni aims to deploy the platform in the Japanese market as well as other markets in Asia and has been conducting verification experiments since the signing of a business partnership agreement with Circularise in February 2021. Furthermore, in May 2021, Marubeni successfully input information on plastic recycling verification experiments into Circularise’s platform and created DPP as part of the “Digital Product Passport Study Group” launched by J-CEP*4 in March 2023.

Through its participation in the exhibition, Marubeni seeks to expand collaboration possibilities with various companies and organizations and contribute to the realization of a circular economy by implementing the still-new concept of DPP in Japan, thereby promoting sustainable product design and improving transparency in resource procurement.
