Abstract

To mitigate the various socioeconomic/environmental consequences associated with plastic waste, it is crucial to adopt strategic measures aimed at source reduction. In this regard, the thermo-chemical approach is a promising technical option to realize this objective within the framework of the circular economy. Such approach involves transforming plastic waste into chemicals/fuels, which contributes to the build-up of a more sustainable and resource-efficient platform. Precise control over yield and selectivity towards target chemicals (monomers, light olefins, and benzene, toluene, ethylbenzene, and xylene isomers (BTEXs)) and fuels (transportation fuels and syngas) is achievable by manipulating operating parameters for the thermo-chemical platform despite the possibly marked influence of the waste composition on product distribution. This review aims to delineate a technically viable pathway of the thermo-chemical approach with the discussion on the physico-chemical properties and compositional characteristics of plastics, technical alternatives for their recycling, and the associated environmental risks (improper disposal practices including mismanagement, landfilling, and incineration). This review helps open a new path for the development of a strategic technical approach within thermo-chemical processing to integrate different facets of plastic waste recycling. Thus, it will contribute to the realization of a closed-loop circular economy within the plastic value chain by focusing on thermo-chemical recycling of plastic waste.

期刊介绍： Progress in Energy and Combustion Science (PECS) publishes review articles covering all aspects of energy and combustion science. These articles offer a comprehensive, in-depth overview, evaluation, and discussion of specific topics. Given the importance of climate change and energy conservation, efficient combustion of fossil fuels and the development of sustainable energy systems are emphasized. Environmental protection requires limiting pollutants, including greenhouse gases, emitted from combustion and other energy-intensive systems. Additionally, combustion plays a vital role in process technology and materials science. PECS features articles authored by internationally recognized experts in combustion, flames, fuel science and technology, and sustainable energy solutions. Each volume includes specially commissioned review articles providing orderly and concise surveys and scientific discussions on various aspects of combustion and energy. While not overly lengthy, these articles allow authors to thoroughly and comprehensively explore their subjects. They serve as valuable resources for researchers seeking knowledge beyond their own fields and for students and engineers in government and industrial research seeking comprehensive reviews and practical solutions.
