As part of the First Circular Design Internship in UL, Ireland, a full-day masterclass was conducted by Dr. Sharon Prendeville, Loughborough University, UK, on September 5th, 2017. The masterclass covered key concepts of circular economy, material flows and stakeholders. In addition, the interns had the chance to experience stakeholder mapping and business model canvas tools to have a better understanding of these concepts and their relevance to the project briefs they received. UL Circular Design Internship team expresses upmost gratitude to Sharon Prendeville for this masterclass.
