Sara Wingstrand, new plastics economy research analyst from the Ellen MacArthur Foundation, talks to Ian Welsh about plastics and the essential transition from a linear to a circular economy. They discuss why plastic is a resource and how circular economy principles can develop a restorative economy by design. Wingstrand argues that business models need to change, and companies need to think about how they can eliminate single use plastic products. She highlights how some companies are changing to have re-use business models, focusing on the service they provide and new ways to deliver it.
