The book takes a multi-level perspective, focusing on circular business models by manufacturing industries in European small open economies. The book conceptualises circular business models and combines theoretical foundations with best practices when such models appeared in the textile, furniture, and plastics industries. It also explores barriers, drivers, challenges, and opportunities for leading manufacturing companies to implement circular activities across the value chain. This book offers a qualitative and transformative approach, spread across three different manufacturing industries, towards a circular transition. The findings will be of interest to practitioners and managers, policymakers, and general readers who are interested in the circular economy and environmental sustainability.
