## Description

Circularise, founded in the Netherlands in 2016, offers blockchain-based supply chain transparency for chemicals, plastics, battery materials and metals. The system uses a public blockchain instead of private consortium blockchains — ensuring sustainability proofs cannot be double-used. Smart contracts replace manual mass balance bookkeeping in Excel spreadsheets.

Circularise enables companies along the chemical and recycling value chain to track materials and share their ecological footprint — without disclosing sensitive business data. In September 2022, Circularise conducted the first blockchain pilot for mass balance certification with ISCC and 10 companies: material suppliers Neste, Asahi Kasei, Borealis, Trinseo and Shell; brands and OEMs Arcelik, Philips Domestic Appliances and EVBox; trading companies Marubeni and Itochu. The public blockchain makes sustainability proofs systemically non-reusable. Circularise has also collaborated with SABIC on Scope 3 blockchain tracking and built a digital platform for plastic recycling monitoring in Europe with EuPC (European Plastics Converters). The system approach supports Digital Product Passports, the EU Battery Regulation and the German Supply Chain Due Diligence Act.
