Abstract

In response to the historic resolution endorsed by the United Nations (UN) to end plastic pollution, completely mitigating ubiquitous plastic pollution would be challenging if substantial advancements are not made towards sustainable plastic management. Therefore, this review aims to provide valuable insights into practical technical routes for plastic pollution mitigation, aligning with the goals of the UN treaty on plastic pollution. This review discusses current technological advancements and proposes innovative solutions for achieving a circular plastic economy. Compared with traditional incineration and mechanical approaches, advanced thermochemical approaches and multifunctional catalytic techniques are the most promising approaches for plastic pollution mitigation owing to their higher economic feasibility and environmental benefits. Machine learning-guided valorizations of plastic waste into value-added products are promising and feasible routes for efficiently optimizing plastic valorization systems and accurately designing high-performance catalysts. Finally, this review offers an outlook and a roadmap on the valorization and innovation of plastic waste for achieving energy and environmental sustainability, which are also beneficial in achieving several UN sustainable development goals, Environmental, Social and Governance, and carbon neutrality.

期刊介绍： Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
