Summary: Waste-to-energy technologies provide sustainable solutions for waste that cannot be further reused or recycled. This paper focuses on the direct combustion in incineration plants and examines the main process, technologies applied, and environmental aspects. The study analyzes flue gas emissions, with a particular focus on the CO2 parameter, to understand the impacts of these processes. The aim is to fill the gap in understanding the emissions and possible reduction of CO2 from these types of plants.

Summary: China, as the largest developing country, has been facing an increasing amount of municipal solid waste (MSW). Incineration is the mainstream method for MSW treatment, but air pollution emissions have been a major concern. The Chinese government is committed to implementing MSW classification, but specific models and reduction targets are still unclear. This study projected scenarios of air pollution emissions until 2030 based on different MSW classification models and diffusion rates of ultra-low emission technology. The results provide valuable references for MSW management and air pollution reduction in China.

Summary: This study investigated the denitrification process in municipal solid waste incinerator based on coupling technologies of flue gas recirculation, over-fired air, and selective non-catalytic reduction through numerical simulation. The results demonstrated that the application of flue gas recirculation, especially at a ratio of 20%, significantly reduced NOx emissions and improved boiler efficiency. When coupled with over-fired air technology, the selective non-catalytic reduction technology further enhanced the removal efficiency of NOx. Overall, the coupling of these technologies achieved a high NOx removal efficiency of 76.48%.

Summary: Compared to landfill, MSW incineration not only eliminates secondary pollution and land occupation, but also achieves a net emission reduction. However, incineration fly ash produced in the process contains potentially toxic elements and dioxins. Therefore, a harmless integrated scenario for the co disposal and resource reutilization of MSW and its hazardous ash is proposed. By using an IFA melting furnace, the toxic dioxins are burned out and the potentially toxic elements are solidified into molten slag for high value-added rock wool production. This scenario leads to collaborative reduction, stabilization, harmlessness, and resource reutilization, as well as a net carbon emission reduction and high economic benefits.

Summary: Solids from wastewater treatment can be processed using incineration, pyrolysis, or gasification technologies. Pyrolysis and gasification offer advantages such as tailored production of carbon-rich solids, lower air emission requirements, and smaller flue gas flows, but equipment costs are comparable to incineration at higher capacities. Long-term operational experience will determine the competitiveness and widespread adoption of these technologies.

Summary: This study explores the techno-economic feasibility of a solar photovoltaic (PV) integrated water electrolysis and waste incineration system. Three different strategies were envisioned, with PV + Battery consuming less energy compared to auto-ignition and PV + Secondary-Electrolyzer. However, the capital cost of PV + Battery was higher. In terms of energy consumption relative to waste input, PV + Battery showed the highest reduction, while cost-wise, it was projected to be more expensive in the long run.

Summary: This study uses province-level data from China to analyze the factors leading to inefficiency in sector operation, highlighting industrial SO2 emissions, energy consumption, and NOX emissions as major contributors. It also shows that energy consumption, air pollutant emissions, and output have a higher impact on productivity change compared to non-industrial variables, with technical progress offsetting negative efficiency growth. The Chinese government should focus on improving the efficiency of non-industrial energy consumption and promoting the development of cleaner industries.

Summary: This study demonstrates a method to project HAPs emissions from industrial sectors in the United States using sector-based emissions data and scenario results. The results show diverse regional and temporal patterns among the 237 HAPs considered, with most HAPs having higher projected emissions in 2050 compared to the baseline year, but lower emissions when pollution control and technology improvements are taken into account.

Summary: This paper utilizes panel cointegration and Granger causation approaches to analyze the relationships among CO2 emissions, GDP growth, clean energy generation, and industrial growth for the top ten industrial countries from 1980 to 2014. The study shows that clean energy generation has a statistically significant impact on reducing CO2 emissions in some countries while increasing them in others, and industrial growth also has varying effects on emissions in different countries.

Summary: Municipal solid waste incineration technology has rapidly developed for waste disposal and energy conversion. However, the high content of alkali salts, especially chlorides, in the waste causes severe high-temperature corrosion. High-velocity oxy-fuel spray (HVOF) coating shows promise in mitigating this issue, but the corrosion process involving flue gas and deposits is not well understood. This study investigates the in-service performance and coupling corrosion mechanism. The results provide insights into the corrosion mechanism induced by deposits and flue gas and clarify the resistance of HVOF-NiCr coating through staged characterization.

Summary: The standard methods for assessing the leaching risk of heavy metals from MSW incineration fly ash in a landfill are not effective. This study investigated the leaching characteristics of Cd, Cu, Pb, Zn, Cr, and Ni during the co-landfilling of chelating agents or phosphate stabilized fly ash and MSW under rainfall conditions. The results showed that evaluating the leaching risk according to actual disposal scenarios is a more effective method.

Summary: This article proposes an approach to account for mineral resource dissipation in life cycle inventories, with the application to analyze the direct dissipation of mineral resources along the primary production of copper. The results show that the production of 1 kg of copper cathode generates 0.88 kg of direct dissipative flows of resources, primarily calcium carbonate, copper, and to a lower extent iron. The developed approach may change the interpretation of results regarding mineral resources in LCA and have implications on methodological aspects and data requirements.

Summary: The paper assessed the techno-economic feasibility of renewable energy systems for small-scale mining in Europe, finding that mobile and modular containerised renewable energy systems are technically and financially viable for reducing greenhouse gas and air pollutant emissions in different geographical locations. However, the use of renewable energy in small-scale mining may have both positive and negative environmental and social impacts beyond the mine site, warranting further research.

Summary: Resource dissipation is a barrier to circular economy due to the losses of value and functionality. The economic value dissipation potential (EVDP) method assesses the impacts of resource dissipation by considering dissipative flows and the associated value loss. The method provides complementary information for decision-making processes based on LCA.
