“…As numerous scientific works indicate, the main way to produce cleaner energy [41,42], especially in the era of energy transformation and decarbonization [43], is to employ thermal conversion processes such as pyrolysis [44][45][46], combustion [47][48][49], gasification [50][51][52][53][54] or torrefaction [55,56]. The input material in the above-mentioned processes includes not only commonly used biomass [18,57,58] but also various types of waste [59,60], including plastics (e.g., PP, PET, PE) [61][62][63][64], municipal solid waste (MSW) [65], waste from the recycling of scrap tires [66,67], rural domestic waste [68] and refuse-derived fuel (RDF) [69][70][71][72] and solid recovered fuel (SRF) [73]. The initial stage of both combustion and gasification is pyrolysis [74,75].…”

This article discusses the potential of using computer-simulation methods in processes such as thermal waste conversion, i.e., pyrolysis, gasification, combustion and torrefaction. These methods are gaining in importance, among others, due to the difficulties in execution and high costs associated with conducting experimental research in real conditions or the need to obtain detailed data on the phenomenon under study in a relatively short time. Computer simulation also allows for numerous errors to be avoided, such as those that may occur during optimization activities, the effects of which may have serious consequences, both economic and environmental. In addition to their many advantages, the limitations and disadvantages of using computer-simulation methods were also indicated, mainly related to the interpretation and validation of the results obtained using modelling. Owing to the complexity of the phenomena occurring during thermal conversion, special attention was focused on models based on chemical kinetics, thanks to which it is possible to predict the quantitative and qualitative composition of products in these processes. The aim of this research is to identify the research gap in the field of issues related to models of chemical kinetics of thermal waste conversion processes.

“…They have been widely applied in pyrolysis setups to capture fine particles effectively [206]. For instance, Zhang et al (2023) successfully integrated electrostatic precipitators into their pyrolysis facility, resulting in an impressive reduction in fine particle emissions of over 94%, as observed through long-term monitoring [207].…”

The production of biofuels and biochar through pyrolysis is a promising avenue for sustainable energy generation and waste management. However, this process can inadvertently release various air pollutants into the atmosphere, potentially compromising its environmental benefits. This article provides a comprehensive overview of the gas pollutants associated with pyrolysis for biofuel and biochar production, as well as different variables affecting gas emissions. Key pollutants such as particulate matter (PM), volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), carbon monoxide (CO), and nitrogen oxides (NOx) have been discussed in terms of their formations and emissions during pyrolysis processes. Furthermore, major factors influencing pollutant emissions, including feedstock composition, pyrolysis conditions, and combustion technologies have been examined with up-to-date examples. The review highlights the significance of emission control strategies, such as advanced reactor design, catalyst utilization, and the integration of realtime monitoring systems, in mitigating air pollution from pyrolysis processes. By shedding light on the environmental challenges associated with pyrolysis-based biofuel and biochar production, this article aims to encourage the development of cleaner and more sustainable approaches to harness the potential of solid waste conversion technologies.
