<p>The increasing global demand for sustainable energy solutions, coupled with the environmental challenges posed by plastic waste, has prompted the exploration of innovative technologies for hydrogen production. Conventional processing methods often result in inefficient resource recovery. Pyro-gasification, a two-step thermochemical process and an emerging solution, has garnered attention as a promising method for producing hydrogen from plastic waste, offering an eco-friendly approach to waste reduction, environmental protection, and the production of clean energy. This review provides a comprehensive analysis of pyro-gasification technology and its potential for sustainable hydrogen production. It explores the fundamental principles of pyro-gasification, the suitability of different plastic types as feedstocks for the process, the various operational parameters that influence hydrogen yield and examines the advantages and challenges of integrating pyro-gasification with plastic waste management and energy production systems. Furthermore, the paper highlights recent advancements in reactor design, catalyst development, and process optimisation to enhance pyro-gasification for efficient hydrogen production. The review concludes by discussing prospects, technological hurdles, and the role of policy and economic factors in advancing pyro-gasification as a viable solution for sustainable hydrogen production from plastic waste.</p>
