Digital technologies drive the circular economy by improving waste-sorting, identifying materials, and working out the best routes for resources to be reused or recycled. U.S. retail product cloud developer EON, for example, proposes a digital identity for retail products containing information about the materials they are made of. The data is embedded in the product and goes with it from production to sale, use, reuse and recycling. Starting with the fashion sector, EON plans to bring 400 million products online with its CircularID™ Protocol by 2025.
