“…As mentioned previously, a non-negligible increase in the CH 4 content was observed for the two last tests, relative to homologous tests conducted at the same temperature (i.e., test # 10 vs. tests # 1 and # 8, test # 11 vs. test # 9). Because of the increase in CH 4 (and tar content) correlated to the higher SRF fraction in the fuel feed, it is fair to expect an increase in the contents of light hydrocarbon species such as ethylene, ethane, or acetylene (although these were not directly measured), as previously reported [67][68][69]. However, it can be assumed that these compounds are not in significant quantities, thanks to the appreciable content of hydrogen measured in the produced gas.…”

“…However, pyrolysis is more omnivorous and can easily intake a mix of plastics (usually polypropylene, polystyrene, and polyethylene). Finally, gasification can be applied to mixed waste but it is sensitive to corrosion, given the high operating temperatures (Tullo 2019 ; Weiland et al 2021 ).…”

Plastic usage increases year by year, and the growing trend is projected to continue. However as of 2017, only 9% of the 9 billion tons of plastic ever produced had been recycled leaving large amounts of plastics to contaminate the environment, resulting in important negative health and economic impacts. Curbing this trend is a major challenge that requires urgent and multifaceted action. Based on scientific and gray literature mainly published during the last 10 years, this review summarizes key solutions currently in use globally that have the potential to address at scale the plastic and microplastic contaminations from source to sea. They include technologies to control plastics in solid wastes (i.e. mechanical and chemical plastic recycling or incineration), in-stream (i.e. booms and clean-up boats, trash racks, and sea bins), and microplastics (i.e. stormwater, municipal wastewater and drinking water treatment), as well as general policy measures (i.e. measures to support the informal sector, bans, enforcement of levies, voluntary measures, extended producer responsibility, measures to enhance recycling and guidelines, standards and protocols to guide activities and interventions) to reduce use, reuse, and recycle plastics and microplastics in support of the technological options. The review discusses the effectiveness, capital expenditure, and operation and maintenance costs of the different technologies, the cost of implementation of policy measures, and the suitability of each solution under various conditions. This guidance is expected to help policymakers and practitioners address, in a sustainable and cost-efficient way, the plastic and microplastic management problem using technologies and policy instruments suitable in their local context.

Chemical upcycling of waste plastics into high‐value‐added products is one of the most effective, cost‐efficient, and environmentally beneficial solutions. Many studies have been published over the past few years on the topic of recycling plastics into usable materials through a process called catalytic pyrolysis. There is a significant research gap that must be bridged in order to use catalytic pyrolysis of waste plastics to produce high‐value products. This review focuses on the enhanced catalytic pyrolysis of waste plastics to produce jet fuel, diesel oil, lubricants, aromatic compounds, syngas, and other gases. Moreover, the reaction mechanism, a brief and critical comparison of different catalytic pyrolysis studies, as well as the techno‐feasibility analysis of waste plastic pyrolysis and the proposed catalytic plastic pyrolysis setup for commercialization is also covered.
