Plastic Waste Valorization

This work presents a comprehensive and forward-looking exploration of one of the most pressing environmental challenges of the 21st century plastic waste and its transformation into high-value nanomaterials. Drawing on recent scientific advances, the book critically examines the global plastic pollution crisis, highlighting its environmental, economic, and public health implications, while situating the problem within both global and African (particularly Nigerian) contexts. Moving beyond conventional waste management approaches, the text introduces the concept of waste valorization within a circular economy framework. It systematically explains how plastic waste can be re-engineered into functional nanomaterials, with particular emphasis on carbon-based nanomaterials and carbon dots. The book provides a detailed treatment of polymer science fundamentals, degradation mechanisms, and the chemistry underpinning plastic materials, before advancing into nanotechnology principles and synthesis technique. In addition, it explores wide-ranging applications of these nanomaterials in different fields. This book positions plastic waste not as environmental burden but as a valuable resource.
