📄 Abstract（原文）

Plastic waste and emissions generated by aviation are among the pressing concerns facing a regenerative low carbon future. Global production of plastic has touched about 460 million tonnes as per 2019 data, while plastic waste generation stood at 353 million tonnes in the same year. However, less than 9 percent of plastic waste was successfully recycled, where nearly 50 percent went to landfills, while another 22 percent was improperly managed in the form of unregulated disposal, burning, and leaking in the environment. On the other hand, aviation resulted in nearly 950 million tonnes of carbon dioxide emissions in 2023, making up 2.5 percent of energy-related emissions globally. This research study focuses on exploring the potential use of mixed plastics as a feedstock to convert into renewable aviation fuel using thermochemical routes. The problem with recycling of mixed plastics is related to contamination, heterogeneity, and variability in composition. Rather than handling them as waste, this study aims to utilize mixed plastics to produce valuable liquid fuel fractions that can be upgraded into aviation-range hydrocarbons. The research is concerned with process efficiency, fuel quality enhancement, carbon reduction prospects, and the more extensive impact of fuel produced from waste in regenerative societies. This research addresses the conference topics such as circular urban metabolism, zero waste policy and strategy, sustainable infrastructure, and climate resilience. Moreover, the research aligns well with responsible consumption and production, sustainable energy transition, innovation in industry, climate action, and sustainable infrastructure. Since waste plastic can be recycled into sustainable fuel, this research identifies an opportunity to ease landfill strain, capture carbon and contribute to aviation decarbonization through sustainable fuel usage. Since sustainable aviation fuel may account for 65 percent of necessary reductions in order to help aviation become net zero in 2050, waste-based SAF represents a vital way to foster mobility and regeneration..
