Summary: This study investigated the abiotic decomposition of simulated Municipal Solid Waste (MSW) and its impact on landfill gas components. The results showed that the gas composition and temperature were influenced by the heating rate and time. Higher heating rates led to a decrease in the CH4/CO2 ratio, and the release of hydrogen was directly proportional to the amount of CH4 available in the system.

Summary: The USA, China, and India are the top producers of municipal solid waste, with waste composition varying based on income levels. Municipal solid waste management options include recycling, incineration, waste-to-energy conversion, composting, or landfilling. Landfilling is a preferred method globally, with critical factors for sustainability including liners, soil cover thickness, leachate collection, and gas recovery facilities. Landfills act as ecological reactors undergoing various transformations, with bioreactor landfills emerging as a next-generation solution for efficient waste stabilization through controlled recirculation.

Summary: The study found that material production contributes 68-75% to toxicity impacts in the landfill while LFG emissions contribute 50-99% to global warming, ozone depletion, and smog impacts. The current non-methane organic compound regulatory threshold reduces methane emissions by <7% relative to the former threshold.

Summary: Quantities of waste are increasing daily, with most disposed through open dumps and landfilling. Landfills produce major greenhouse gases, with methane having a global-warming potential 21 times higher than carbon dioxide. This study aims to estimate carbon storage in municipal solid waste (MSW) burial at Mavallipura landfill, finding an increase in carbon stored with depth. Additionally, the study quantifies methane-gas production from the ward levels and the Mavallipura landfill site in India.

Summary: Proper management of municipal solid waste (MSW) is crucial to avoid pollution, environmental impacts and threats to public health. This study evaluated the impact of management practices and environmental risks at two landfill sites. The analysis showed significant differences in vegetation between the two sites, with invasive and expansive species dominating one site. These environmentally problematic species can spread from the landfill into adjacent ecosystems and degrade farmland areas.

Summary: Municipal Solid Waste (MSW) is disposed of in an unorganized and disordered manner, leading to severe environmental consequences and health hazards. Landfills in India require a large amount of land and only 21% of MSW is properly managed. Landfills contribute significantly to greenhouse gas emissions and are expected to cause a substantial increase in global emissions in the future.

Summary: The study showed that early addition of liquid waste did not stimulate anaerobic decomposition of fresh MSW, and most liquid wastes were not suitable as the sole moisture source for bioreactor landfills. MSW reactors co-disposed with sludge produced more methane, while reactors co-disposed with gypsum board or foundry waste also generated methane, despite inhibitory effects indicated by biochemical methane potential (BMP) results.

Summary: This study estimates the carbon emissions from municipal solid waste treatment across 30 Chinese provinces from 2011 to 2020. The results show that technological advances in waste treatment are the main driver of national carbon emissions reduction. Additionally, the impact of policies on carbon emissions changes is further analyzed using the LMDI-PDA model, considering socio-economic factors. The methods and results of this study can provide better decision-making support for national and provincial carbon emissions control policies targeting MSW treatment.

Summary: Industrial parks provide opportunities for Process Integration among different enterprises. Inter-Plant Water Network Integration is an effective strategy for water conservation. This study develops a Vulnerability Assessment Framework to analyze failure propagation in water networks in an industrial park. The results show that the supply-driven Inoperability Input-output Model (IIM) is more suitable for cascading failure analysis of water networks. This work can help identify system vulnerabilities and provide a scientific insight for the development of park-wide water management strategies.

Summary: With the increase in population and living standards, the amount of municipal solid waste (MSW) has rapidly increased, posing economic and environmental challenges for cities in developing countries. This paper proposes an integrated framework that combines grey system theory and mathematical programming model to address MSW management. The factors affecting MSW generation are analyzed using grey correlation analysis and the generation of MSW is predicted using the grey model GM (1,1). The paper also presents a multi-period planning model to optimize MSW management, considering different scenarios and providing useful findings for decision-makers in adopting effective policies.

Summary: This study analyzes the characteristics of process parameters in three lean gas ethane recovery processes and establishes a prediction and multiobjective optimization model for ethane recovery and system energy consumption. A new method for comparing ethane recovery processes for lean gas is proposed, and the addition of extra coolers improves the ethane recovery. The support vector regression model based on grey wolf optimization demonstrates the highest prediction accuracy, and the multiobjective multiverse optimization algorithm shows the best optimization performance and diversity in the solutions.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.

Summary: This study uses survey data from the Loess Plateau in China to evaluate the impact of social interaction on the adoption of soil and water conservation (SWC) technology by farmers. The study finds that social interaction increases the likelihood of farmers adopting SWC, and internet use moderates this effect. The positive impact of social interaction on SWC adoption is more pronounced for farmers in larger villages and those who join cooperative societies.
