TheHandbookintroduces, contextualises, critiques, and discusses a range of perspectives associated with the concept of the circular economy. These perspectives span an array of subjects including economics, environmental policymaking, sociology, environmental science, environmental and industrial engineering, management, international development, and human geography. A fundamental underpinning of theHandbookis that it takes account of a wide range of sectors, as well as geographical perspectives that incorporate both a Global North and Global South world context. This approach is crucial because it is only within such a holistic perspective that the circular economy concept can truly be examined. In addition, these issues are examined both from a theoretical as well as a practical perspective, using real world case studies for illustration. Given its wide subject, sectoral and geographical areas of focus, theHandbookshould be of value not only for those undertaking research in the field of circular economy, but also stakeholders involved in policymaking, as well as decision-making on the front line.
