Abstract

Creating accurate models to explain the reaction mechanisms in thermochemical processing of solid polyolefins and their derivatives using non-thermal plasma (NTP) technology is crucial for improving recycling and reuse efforts. This area has gained significant attention over the past few decades. The model for polyolefin breakdown involves a mix of complex free radical reactions, along with formal and molecular processes. NTP reactors provide an environment with enhanced reactivity and performance, making them highly efficient for treating solid polyolefins and ideal for producing clean energy and other valuable products from polyolefin waste. Therefore, developing adaptable and precise simulations to identify the best geometric configurations for NTP reactors is key to improving their performance. Utilising various computational techniques and integrating suitable algorithms to build models that meet design goals and predict results offers a cutting-edge approach for engineering applications. Mathematical modelling and cutting-edge computational simulations can enhance themselves by incorporating data and verifying results experimentally, with a focus on linking inputs to anticipated results. This method is crucial in interpreting the mathematical connections among various intricate procedures and actual response circumstances. In this study, a concise overview of new, promising research advances in the treatment of polyolefin waste using NTP has been presented. The…
