Site selection of new landfills for municipal solid waste (MSW) disposal is a great concern of urban governments around the world as old landfill sites are being filled-up and demand for new sites is increasing. Finding a suitable MSW disposal site of adequate size meeting all the regulations is a costly endeavor. With the advent of geographic information systems (GIS) and its decision support ...

site selection is an important and necessary issue for waste management in fast-growing regions. because of the complexity of waste management systems, the selection of the appropriate solid waste landfill site requires consideration of multiple alternative solutions and evaluation criteria. this paper addresses the sitting of a new landfill using a multi-criteria decision analysis (mcda) and o...

landfill is one of the primary methods for urban solid waste disposal. in order to reduce theenvironmental adverse effects and to protect the public health and human welfare, evaluating the landfill isutmost importance. in this research work evaluation procedure for the current condition of ahvaz city urbansolid waste landfill site with criteria of local screening method (lsm) is outlined. in t...

This study investigated two methods for the removal of COD and colour from sanitary landfill leachates. The first method involved the use of coagulation/flocculation process using FeCl3 as a conventional coagulant and Ca(OH)2 as base-precipitant. The second method involved integration of Fenton’s reagent into the coagulation/flocculation process. Concentration of FeCl3 that reduced chemical oxy...

background: predicting the methane percentage of biogas is necessary for selecting the optimized technologies of using landfill biogas for energy. the aim of this study was to predict of methane fraction in biogas from landfill bioreactors by artificial neural network (ann) modeling. methods: in this study, two different systems were applied to predict the methane fraction in landfill gas as a ...

The Vejen Landfill leachate plume was characterized in detail in 1989 in terms of redox zones and distribution of organic pollutants. Strong natural attenuation was observed for most organic compounds in the strongly anaerobic part of the plume. A visit to the plume 10 years later revealed that the NVOC plume had spread further, but that most of the chemical compounds still were attenuated in t...

solid waste municipal landfill can have significant health, economic and environmental effects. therefore, there is a need to comprehensive land evaluation for locating the best landfill place. the purpose of this paper is showcasing the process undertaken to locate the best landfill site for municipal solid waste of golpayegan township. at first, three alternatives were proposed after field su...

to examine how water retention characteristics in a landfill environment change as a result ofsolid waste settlement and to derive the evolution of pore size distribution, a lab scale long column experiment was carried out at two different time periods while keeping all the other characteristics constant. two columns, column 1 and column 2, were used in the study. the log normal distribution mo...
