The increase in municipal solid waste (MSW) in northwest China has been substantial, with a significant portion primarily treated in landfills. This rapid growth in waste generation presents considerable challenges for landfill management and treatment. The factors affecting MSW degradation are...
Solid Waste Management
Delegating public solid waste management services to private structures is increasingly favored by some countries in sub-Saharan Africa. However, waste is still landfilled without recycling and/or recovery of any fraction. This study investigated the generation, characteristics and current...
Sustainable Energy
The intensifying environmental and energy-related issues have led to a significant surge in the need for discovering alternative fuel sources. Additionally, the labor and time involved in identifying the appropriate fuel for the engine being examined is considerable. In order to mitigate this...
Water and wastewater treatment and reuse
The complex composition of persistent and resistant contaminants in oil refinery wastewater presents a significant environmental challenge that conventional treatment methods frequently fail to effectively address. Advanced Oxidation Processes (AOPs), specifically the photo-Fenton method, and a deep...

The carbon abatement effects of digital finance (DF) have been widely studied, but existing studies have neglected its impact on the marginal carbon abatement cost (CMAC). The paper uses the SBM model to measure the CMAC of 264 cities in China for 2011-2021 and then constructs a two-way fixed...
Water and wastewater treatment and reuse
The influence of land-use patterns on water quality in the Huaihe River Basin was analyzed using the Nemerow index, correlation and multiple linear regression analysis based on the measured data from 62 sampling sites in the Huaihe River Basin (China). In the point buffer zone, a significant...
Solid Waste Management
Discrete studies are performed on the reuse of end-of-life tires in the construction industry as their accumulation is a global concern to the environment. In consequence, the desired focus of this work is to understand the interaction of powder derived from recycling process of tire waste which yet...
Hydrology and Water Resources Management
The purpose of soil hydraulic conductivity is to retain soil water contents, and soil water pressure. In this study investigates two different methods to understand the soil hydraulic conductivity of loam and clay soils. The present research conducted a laboratory experiment to measure the saturated...
Air pollution and health
The purpose of this study is to anticipate and investigate the groundwater quality in the regions of the Cauvery basin. In the post-monsoon season of 2020, 800 samples were collected from 200 different places for this paper. The AlexNet model is used in this book to forecast the water quality. In...
Air pollution and health
Groundwater is a vital resource for human consumption. The study aimed to evaluate toxic metal concentrations in groundwater systems and determine pollutant sources using multivariate methods including cluster analysis (CA), principal factor analysis (PCA), and Pearson correlation coefficient (r)...
Solid Waste Management
Population growth, industrialization and technological advances have significantly increased waste production, waste collection, transportation and disposal induced significant costs. Waste could be considered a resource that allows nations to reduce the consumption of primary raw materials, protect...
Solid Waste Management
The Coordinated management of solid waste dumps from different anthropogenic environments is important for pollution management of immediate and adjacent ecosystems. This study took three soil profile samples from three functional zones: the rural, the suburban, and the urban solid waste dumps. The...
Air pollution and health
The present study aimed to compare the concentration of 14 metals in the air of 4 cities of Khuzestan province (Ahvaz, Dezful, Mahshahr, and Abadan) in dusty and non-dustynon-dustyy conditions, and determine risk and non-carcinogenic risk in a six-month period from 2017 to 2018 (autumn, winter, and...
Air pollution and health
Environmental protection and the need for accurate pollutant forecasting have become increasingly important as worries about environmental issues and the harmful effects of pollution have grown. Predictive accuracy of air pollutants is generally unsatisfactory due to the fact that conventional...
