Abstract: Abstract Municipal solid waste landfills are the third-largest anthropogenic source of methane (CH4) emissions in the United States, contributing significantly to climate change. Although engineered landfills utilize gas ...

Abstract: A long-term soil column study was carried out to investigate the methane (CH4) removal capacity of landfill cover soil and biochar-amended cover soil under simulated landfill cover conditions. Terminal batch assays were ...

Abstract: Abstract This study employed a recently developed coupled thermo–hydro–bio–mechanical model to evaluate the effects of physical, biochemical, and thermal characteristics of municipal solid waste (MSW) on the long-term ...

Abstract: Bioreactor landfills using leachate recirculation in municipal solid waste (MSW) undergo complex interrelated hydraulic, mechanical, and biochemical processes. In this study, the authors present a mathematical framework ...

Abstract: Nanoscale iron particles (NIP) have been found effective for remediation of contaminated groundwater, but their transport in subsurface after injection is limited due to aggregation and sedimentation. Lactate-modified NIP ...

Abstract: The present study investigated the effectiveness of two soil-bentonite slurry wall backfills, specifically sand/conventional Na-bentonite (NaB) and sand/hexametaphosphate (SHMP)-amended Ca-bentonite (SHMP-CaB), for the ...

Abstract: A new and innovative binder KMP is developed for solidification/stabilization (S/S) of soils contaminated with heavy metals such as lead (Pb), zinc (Zn), and cadmium (Cd). The KMP consists of acid-activated phosphate rock, ...

Abstract: Increased use of industrial residues for soil stabilization is a necessary practice for sustainable geotechnics. The present study investigates carbide lime, the residue resulting from the production of acetylene gas, for ...
