Mesbah learned the value of hard work as an Afghan refugee; his family sought asylum in his adopted homeland of the Netherlands when he was just seven years old. His can-do philosophy – and his belief that it’s tough to solve big problems from inside big companies – inspired the creation of Circularise four years ago. The digital technology startup is using blockchain to create a platform for sharing data across supply chains. The ambition is to improve transparency so that companies can move toward more circular production processes, starting with the plastics sector.
