Incineration is a widely used and well established technology for the municipal solid waste (MSW) management. Modern MSW incineration plants are equipped with improved air pollution control (APC) systems, which reduce pollutants well below the established limits. The environmental concern has, thus, moved from the air emissions to the solid residues generated from the APC systems of the inciner...

EU Landfill Directive (1999/31/EC) requires the gradual reduction of biodegradable municipal waste going to landfills. In this context, three mechanical-biological treatments (MBT) plants were designed and installed progressively in Barcelona Metropolitan Area (Catalonia, NE Spain) during 2000s. These facilities were intended to solve the problem of municipal wastes generated in this region (Ta...

Landfill behavior is dependent on the composition and characteristics of region’s municipal solid waste (MSW) environment conditions. In landfills that are difficult to understand, MSW undergoes several complex mechanisms such as physical, chemical, thermal biological processes throughout its lifespan. present research, by setting up an anaerobic reactor, attempt was made understand processes. ...

Municipal solid waste (MSW) management has become a major concern for developing countries. The physical and chemical aspects of MSW infrastructure need to be analyzed critically solve the existing socio-economic problem. Currently, production is 2.01 billion tonnes/yr. In countries, improper poses serious environmental public health risks. Depending on framework country, several procedures hav...

Municipal solid waste (MSW) incineration fly ash (IFA) can be potentially reused as a substitute for some raw materials, but treatment for detoxification is indispensable owing to high contents of heavy metals in fly ash. In the present work, due to excessive leaching concentration of lead (Pb), a moderate thermal treatment with sodium hydroxide (NaOH) addition was employed to stabilize Pb in I...

Simulated municipal solid waste (MSW) based on the actual proportional characteristics of MSW was loaded into a simulated leachate recirculation bioreactor landfill and the abundance of common and tolerant microbes exposed to dibutyl phthalate (DBP) were investigated in the initial, acidic and methanogenic phases. The results showed that the abundance of bacteria was greatest, while that of act...

There are numerous active and abandoned waste sites in the US and worldwide. Post‐closure development of these sites is desirable from an environmental, societal and economical perspective. However, the post‐closure development of landfills presents many challenges. A major challenge is the generally soft nature of the municipal solid waste (MSW) and the high pote...

Surface spraying, horizontal trenches, and vertical wells are the most common leachate recirculation system used at landfills in engineering practice. In order to quantify efficiency of three aforementioned systems, a hydro–biochem–mechanical-coupled model was developed present work, which can describe hydrodynamic biochemical behaviors food-waste-rich landfills. A typical landfill cell modeled...

The global warming potential (GWP) of methane (CH4) is 25 times the GWP of carbon dioxide (CO2); as such, controlling CH4 emissions at municipal solid waste (MSW) landfills is an urgent task. Oxidation of CH4 using soil covers and bio-enhanced covers as a CH4 mitigation strategy is receiving great attention from environmental professionals. Biochar-amended soil covers are proposed to effectivel...

Landfill gas (LFG) is a potent greenhouse gas (GHG) generated by anaerobic degradation of decomposable municipal solid wastes (MSW). LFG contains (50-60%) of methane (CH4) and (40–50%) carbon dioxide (CO2). If a landfill is neither aerated nor equipped with gas capture systems, the LFG emissions, mainly CH4, in the cover soil is best reduced by using a biocover. Biocovers normally act as a biof...
