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...

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...

As an important resource for the IT sector and due to the extremely hazardous elements it contains and the low recycling rate, e-plastic waste management and recycling are growing swiftly. E-plastic waste utilization reduces aggregate costs, landfill costs and energy prices. Rapid population growth...

This study utilized a series of experimental tests, including the Atterberg limit, standard Proctor, permeability, and direct shear tests. Three composites were investigated: 85% fly ash-10% bentonite (V1), 90% fly ash-5% bentonite (V2), and 95% fly ash-0% bentonite (V3). All composites contained 5%...

Dewatered sludge is the main by-product from wastewater treatment and it contains various types of hazardous substances which can cause environmental pollution. The alternative utilization of sludge waste is for covering the landfill or as liner for the landfill. Landfill cover is a critical...

This paper presents the results of an experimental study carried out in field-scale test cells in order to determine the effect of aeration and leachate recirculation on waste decomposition rate, solid waste characteristics, landfill gas composition and settlement in the landfill body. Four landfill...

Uncontrolled landfill leachate generation portends danger to the environment and aquatic ecosystem, especially without prior treatment before discharge. The application of Al-based coagulants, such as polyaluminum chloride (PACl), has the potential of introducing Al residuals into water bodies...

Emission of CH4 from landfills is a major cause of concern as CH4 is twenty four times more potent than CO2, as a greenhouse gas. However, landfills also harbor a group of bacteria called methanotrophs, which can oxidize CH4. They can be used for in situ bioremediation to reduce methane emissions...

Municipal landfill leachate generated from aged sites requires an efficient treatment to minimize the high level of refractory organic matters prior to final discharge. In the current study, the performance of combined ozonation and Zinc sulfate (ZnSO4) for anaerobic stabilized leachate treatment...

A comparative economic and life cycle based analysis of five management scenarios for the solid waste generated in the island of Syros was conducted. The LCA part was performed with the LCA – IWM software. The four on-site waste management scenarios were: i) source separation of recyclable materials...
