...Guangyao Li; Xiaobing Xu; Cheng Feng; Jie Hu; Yunmin Chen The drawdown performance of conventional leachate pumping wells in municipal solid waste ( MSW ) landfills is often variable and sometimes unsatisfactory. The integration of vacuum-assisted vertical leachate pumping wells has shown...

...Shi-Feng Lu, PhD; Xing-Rui Wang, MSc; Xiao-Pei Guo, MSc Understanding the coupled bio-thermo-hydro-mechanical responses of municipal solid waste (MSW) in landfills is crucial for sustainable landfill design and proper risk management during its service life. The objective of this study...

... regulations on landfills contain detailed instructions for monitoring the impacts of pollution from leachate on water, air and soil. However, references to the impact of landfills on the landscape and the need to monitor the surrounding vegetation are described only in general terms. Studies have indicated...

... in this paper are simpler and have a quicker convergence speed. Also, the proposed analytical solutions are more practical with clear expressions and consideration of multiple factors, which can be applied to various engineering cases such as bottom liner systems at landfills, covering systems of contaminated...

... in municipal solid waste landfills (including dumpsites) is a complex and intricate phenomenon, frequency of which is expected to increase due to climate change. Partial or incomplete combustion of landfill waste at low temperatures during fires leads to the generation of toxic compounds, including...

...Manikanta Devarangadi, PhD; Uma Shankar Masilamani, PhD This work examines the engineering properties and leachate characteristics of ground granulated blast-furnace slag (GGBS) blended with laterite soil–bentonite mixtures as a bottom landfill liner. In this study, laterite soil is considered...

... ways. One pathway is not to fragment IBA and use it as a building material in road construction. This results in reduced landfilled residual but low metal recovery. The other way is to crush the mineral aggregate, thus maximising metal recovery but resulting in higher landfilled, end material. Here...

...Qiuju Ke; Chengchao Guo; Huihuan Ma; Fuming Wang Landfill has been a common way to deal with municipal solid waste. It is critical to prevent the leakage of landfill leachate with corrosivity and biotoxicity in landfill sites. Non-aqueous reacting polyurethane grouting material has been...

...Noor Mohammad; Weipeng Meng; Yongmei Zhang; Mingchao Liu; Abbas El-Zein; Yixiang Gan Desiccation cracks in clay play an important role in many geoenvironmental applications such as clay liners in engineered landfills, preferential flows and contaminant transport. In this study, a comprehensive...
