In today's business world, firms and policymakers all utilize circular economy. However, there is a lack of knowledge on how circular economy systems work, which technologies are used, which partners firms should look for, which agreements are required to pursue circular economy, how circular economy interacts with legislation, and what benefits it provides. Additional study on the opportunities and challenges of circular economy is required to ensure business leaders are well informed. Cases on Circular Economy in Practice considers how circular economy systems are implemented and managed in practice, which strategic alliances firms pursue, and how they are coordinated through negotiation and agreements. The book also considers the technologies that circular economy systems use to achieve circularity and how performances are measured in terms of economic, social, and environmental pillars. Covering topics such as blockchain technology, smart cities, and circular business, this reference work is ideal for managers, business owners, industry professionals, researchers, academicians, scholars, practitioners, instructors, and students.
