“…The "principle of subsidiarity" determines who will deal with waste management, taking into account factors such as transport costs, efficiency and benefits resulting from the proximity of the place of waste production and processing [11]. A special group of waste is chemical waste that, due to its properties (flammability, explosiveness, toxicity and others), is classified as hazardous waste [12][13][14] and requires proper handling [15], with particular care. Chemical waste includes waste oils [16], waste-containing asbestos, medical and veterinary waste, expired plant protection products and household chemicals [17].…”

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.

“…However, there still exists a gap in the ecological and environmental quality of the GBA compared with other world-class bay areas, especially in the effective use of solid waste resources [6]. The annual generation of solid waste in all major cities in the GBA is intense, surpassing the 1800 tons per billion RMB generated in the United States [7]. Thus, the rational disposal and utilization of solid waste are imperative for safeguarding the ecological environment and supporting industrial transformation and upgrading in the GBA.…”

“…For instance, Yu et al developed an innovative waste management capacity evaluation model to evaluate the construction waste management capacity of cities in the Greater Bay Area [23], with the objective of balancing waste management across different jurisdictions and policy contexts. Similarly, Xi et al analyzed hazardous waste management in the GBA and provided relevant measures for the safe control and disposal of hazardous waste [7]. While the different political and economic regimes may pose difficulties in waste management in the Bay Area, they also lead to different options and variations in the waste management mechanisms of each city [24].…”

The Guangdong-Hong Kong-Macao Greater Bay Area (GBA) plays an important role in China’s development strategy. With recent GDP growth and high population density, solid waste generation has emerged as a significant challenge for the region. This study sought to clarify GBA’s solid waste management policies by constructing a two-dimensional policy analysis framework covering nearly 99 available policy texts. This quantitative method provides an explanatory framework for solid waste management policy in GBA, identifying the main policy objectives and instruments as well as making comparisons. Additionally, given the variations in policy format resulting from regime differences, this paper utilizes a novel approach to encode the documents. The results of the study indicate that both Macao and Hong Kong have made greater progress than Shenzhen in waste management development. While Shenzhen is primarily focused on source control, Macao and Hong Kong have transitioned to the recycling stage, with Hong Kong having a more advanced system. It is recommended that Shenzhen increase its engagement in information sharing, learning, and collaboration with Macao and Hong Kong. Moreover, it is observed that Shenzhen’s waste management approach relies heavily on administrative measures, whereas Macao and Hong Kong have implemented social participation-oriented and economic incentives-oriented policies, respectively. There is also an adaptation deviation between Waste Collection and Treatment Development (WCTD) and the policy instruments used to achieve it in the three cities. It is imperative that the three governments utilize their policy tools in an effective manner and have a rational use of power and the performance of functions. These findings can provide recommendations for promoting inter-city learning and collaboration in the GBA.
