This book offers an overview of the gasification process as a crucial thermochemical method for addressing the problem of plastic waste. The authors explore various strategies to minimize post-consumer plastic waste and provide a detailed analysis of one of the most promising methods for converting it into high-value products. The chapters reports on the gasification process and its potential for transforming plastic waste into energy and valuable resources. Readers will learn about methods for reducing plastic waste and treating them using the gasification process. Thermochemical processes for upcycling plastic waste into products with higher value, such as chemicals, fuels, and advanced materials are also covered in this book.
