Finland’s Neste (Espoo; www.neste.com) said it plans to track its polymers and chemicals with software developed by Dutch IT firm Circularise (The Hague; www.circularise.com).

The companies also announced that they will further develop digital solutions for tracing renewable and recycled material flows with an aim to improve transparency along the value chain. The Dutch firm’s Traceability brand software is said to be blockchain-based and use a digital twin of physical materials to enable supply chain tracking. This should make it possible to check where materials originated and how and where they were processed.

Neste, which claims to be the world’s largest producer of green aviation fuel and renewable diesel, is currently developing a process for chemical recycling of plastics waste (see Plasteurope.com of 17.01.2022).

Circularise has created a seven-step process whereby raw materials can be identified via a blockchain path to ensure end-to-end traceability. The Dutch start-up has been working with German resin makers Domo (Leuna; www.domochemicals.com) and Covestro (Leverkusen; www.covestro.com) for three years to advance this process (see Plasteurope.com of 14.10.2019).
