To help address the mounting challenges of Africa's most populous city – Lagos, Nigeria – the Global Sustainability Solutions Services of ASU’s Walton Initiatives hosted a three-day workshop there in April 2016. The first of its kind in the world, the "Introduction to Ethical Circular Economy" workshop was hosted at Sustainability School Lagos – an institution modeled after ASU's Julie Ann Wrigley Global Institute of Sustainability. It encouraged the group of 35 students, city and state officials, and others to imagine an economy where resources are remanufactured, refurbished and recycled – nothing is wasted. “There is a tremendous amount of potential for a circular economy in rapidly developing countries,” said Senior Sustainability Scientist and Practice Lead Raj Buch. “It’s where the larger opportunity arises because it’s where most of the economic development is going to happen.” Buch co-led the course with General Manager Dan O’Neill and Olufemi Olarewaju – an Executive Master of Sustainability Leadership graduate and the executive director of the Sustainability School Lagos.
