Circular Plastics Economy: A Multidisciplinary Perspective provides an understanding of the complex issues surrounding plastic waste management, including environmental challenges, risks associated with microplastic contamination, and the detection of micro- and nano-plastics. It explores conventional and emerging technological solutions for plastic waste management, such as reusing, recycling, pyrolysis, and heterogeneous catalysis, while also considering alternative approaches like biochar and microbe-based degradation, fostering a holistic perspective on the transition towards a circular plastics economy. With its multidisciplinary approach, this book provides an analysis of the challenges and opportunities associated with circular plastics economy, guiding the development of sustainable solutions on a global scale. By addressing these diverse perspectives, this book offers a guide for researchers and professionals interested in tackling the challenges of plastic waste to achieve a sustainable and circular approach to managing plastic waste.
