Blockchain for greener metals – tag, trace and trust

Last updated: Jan 22, 2025

Summary

Hydro and DNV GL are initiating a blockchain pilot to document product representations for Hydro CIRCAL and Hydro REDUXA. In this way, the aluminum product passport, with its unique digital ID, attached to the product displays key sustainability facts, such as low-carbon aluminum and post-consumer scrap content

Problem

Customers and their customers request trusted information documenting the footprint from materials and production. There is a need for a platform that supports manufacturers and brands to back their sustainability claims with verified data. That allow them to trace the metal from the factory gates until it reaches the customer.

Solution

Hydro will implement the blockchain-powered “Tag. Trace. Trust.” service developed by DNV GL. It allows anyone to instantly check the validity, data and authenticity of the product’s environmental profile. In the pilot phase, Hydro and DNV GL will work with the sustainable-furniture maker Vestre. The company uses Hydro CIRCAL in selected furniture lines. The product data on the platform gives the company and their customers traceability of the aluminium and the CO2 emissions from raw material to a finished bench in a public park.

Outcome

The next step is to review the experience from the pilot to assess how Hydro can implement the platform to a standardized model. The goal is to roll out the platform to Hydro customers in 2021.
