The management of municipal solid waste presents significant challenges globally. This study investigates the potential of an integrated waste-to-energy system based on circulating fluidized bed gasification technology to address these challenges, while also contributing to renewable energy generation. Using a MATLAB-based simulation model, the study determines the optimal operational parameters for various units within the system, including waste processing, gasification, ash handling, syngas treatment, and emission control. The proposed waste-to-energy system demonstrates a remarkable energy efficiency of 70% under these optimal conditions, notably outperforming conventional waste-to-energy technologies. Sensitivity and uncertainty analyses reveal that waste composition, gasification temperature, and the oxygen-to-solid recovered fuel ratio are key determinants of the system’s output and performance. The system’s performance remained robust despite variations in these parameters, underscoring its potential as a reliable solution for waste management and energy generation. While the findings are promising, future research should focus on comprehensive lifecycle assessment and consider regional factors for practical implementation. This study contributes to the ongoing development of efficient waste-to-energy systems and highlights their potential in promising sustainable waste management and renewable energy production.

Smart waste management is an important tool for energy and resource conservation, and the related recycling and reuse policies are conducive to a positive impact on the ecological footprint. Since waste treatment is a very expensive process, the principle of prevention should be implemented increasingly at the European level to meet the Green Deal’s objectives and related eco-friendly approaches more easily and cost-effectively. Therefore, the rationale of the present work was to statistically study, for the first time, from a waste management viewpoint, the waste categories and quantities produced in the past decade, and mainly eight waste categories were compared at the Romanian versus the European level, including on the level of European regulation implementation. For that, assumptions were made and ANOVA and path analysis were performed. The results of ANOVA emphasizes the differences between the eight types of waste collected, to understand the challenges and the weak points of the member states in their approach to meeting the Green Deal’s objectives and gaining sustainable development. Furthermore, the causes of differences in the European Union’s member states were analyzed in clusters, based on three criteria: total waste, waste management, and waste treatment, and the results are discussed here. The study revealed that Romania proved an increased efficiency in waste treatment and the path analysis proves that waste management is better implemented than treatment management. The study concludes that, regardless of the results obtained so far, further endeavors are necessary at the Romanian governmental level to meet the waste-related European goal.

“…The production of carbon monoxide (CO) decreases as the equivalence ratio of plastic waste and conventional biomass increases, particularly for PP and PE wastes compared to other feedstocks [63]. On the other hand, an increase in equivalence ratio and a rise in gasification temperature lead to an increase in carbon dioxide (CO2) output across all feedstocks.…”

Background For decades, the amount of global plastic waste has been increasing at an alarming level. Traditional landfill and incinerator treatments, on the other hand, result in air pollution and wastage of valuable land. Method This study examined recent advances in the recycling and recovery of plastic waste. A special emphasis was placed on trash derived from polyolefinic sources, which accounts for a substantial part of plastic products used in the daily lifecycle. The mechanical and chemical systems and technologies for plastic waste treatment were detailed and explored in this study. To ensure a comprehensive study, sixty-five (65) papers were carefully selected. The selected papers were published during the period 2015-2023. These papers were searched using web search engine Google Scholar and PubMed database and reviewed to derive meaningful insights. Results The findings determined that chemical recycling of plastic waste is a critical possibility to reduce marine and terrestrial pollution and enable the idea of circular economy to be implemented in today's world. Plastic waste poses both obstacles and opportunities to communities, independently of their level of environmental awareness or technical advancement. Moreover, mechanical processes utilize a variety of waste products as feedstock. Depending on their source, shape, and usage, these waste products can be reduced in size to a more acceptable shape and form (pellets, flakes, or powders). Conclusion Advanced thermo-chemical treatment methods encompass a wide range of technologies that produce either fuels or petrochemical feedstock. Although mechanical recycling schemes are well known and commonly used, many chemical recycling treatment techniques are more productive and widely used due to their economic benefits.
