The first ever World Design Challenge on Sustainable Packaging takes place at the end of May 2021. A collaboration between the World Design Organization and the World Packaging Organisation, the Challenge brings together designers from around the world to take a fresh look at key packaging sustainability problems, and hoping to come up with disruptive design solutions to solve them. Packaging Europe's Tim Sykes gets the inside story from the WPO's Pierre Pienaar and WDO's Srini Srinivasan.
