A one-dimensional multiphase numerical model is developed to simulate the vertical settlement involving liquid and gas flows in a deformable settling municipal solid waste MSW landfill. MSW is represented by a chemical composition, and a global stoichiometric reaction is used to estimate the maximum yield of gas generation. Following the general assumption accepted in the literature, the gas ge...

The annual production of municipal solid wastes (MSW) in Russia, Finland and Ireland in the late 1990s accounts for 37.5, 2.5 and 2.05 min. tonnes or 252, 488 and 566 kg per capita, respectively. 96.5, 64 and 91% of these wastes (for Russia, Finland and Ireland, correspondingly) are currently disposed of via landfilling. However, nowadays, MSW management in these countries is undergoing drastic...

This study aims to investigate the impact of MSW landfill on the contamination of phthalate esters (PAEs) in nearby environment. Landfill leachate, surface water, groundwater and soil profile samples were collected from a MSW landfill area in Wuhan, China. Contents of 16 PAEs were detected for each sample using gas chromatography method. Results showed that landfill had an obvious effect on the...

Sri Lanka is an island in the Indian Ocean with an area about 65 610 km(2). The population of the country is around 20.2 million. Hazardous disposal of municipal solid waste (MSW) is a major concern particularly in the most urbanized areas of Sri Lanka. However, the current waste management system does not facilitate any waste pre-treatment techniques before final disposal. As a consequence, th...

Landfill Gas to Energy This research investigates the utilization of landfill gas, an abundant waste product, by reforming it to syngas that can be converted to liquid fuels using Fischer Tropsch or to a H2 rich stream using water-gas shift. 65% of the 413 million tons of municipal solid waste (MSW) generated per year in the United States is landfilled, and 67% of the landfilled MSW is composed...

This research describes the use of a toxicity assay for the identification of metal toxicity, bioavailability and heavy metal binding capacity (HMBC) of municipal solid waste (MSW) landfill leachates. MetPLATE, an assay specific for heavy metal toxicity, was used to determine the HMBC of MSW leachates collected from 14 sites in Florida, with a wide range of chemical and physical characteristics...

Due to rapid growing of population and active lifestyle, massive amounts municipal solid waste (MSW) are produced worldwide. The MSW can harm the environment threaten land if dumping sites not managed scientifically. geotechnical properties key parameters required in landfill operations management facilities. Hence, presence data assist engineers selecting possible solutions for extension obtai...

Municipal solid waste (MSW) landfills create the environmental pollutions due to problems related toxins, leachate, and greenhouse gas, which are growing concerns, especially in developing countries. This paper presents a novel mathematical modelling for simulating spread of heavy metals soil layers MSW landfills. A new procedure is studied deriving governing equation describes time varying con...

There has been a significant increase in municipal solid waste (MSW) generation in India during the last few decades and its management has become a major issue because the poor waste management practices affect the health and amenity of the cities. In the present study, various physico-chemical parameters of the MSW were analyzed to characterize the waste dumped at Gazipur landfill site in Del...
