In the analysis and design of municipal solid waste (MSW) landfills, there are many uncertainties associated with the properties of MSW during and after MSW placement. Several studies are performed involving different laboratory and field tests to understand the complex behavior and properties of MSW, and based on these studies, different models are proposed for the analysis of time dependent s...
This investigation was conducted to evaluate the influence of waste placement practices on the engineering response of municipal solid waste (MSW) landfills. Waste placement conditions were varied by moisture addition to the wastes at the time of disposal. Tests were conducted at a California landfill in test plots (residential component of incoming wastes) and full-scale active face (all incom...
Recent studies of municipal solid waste landfills have revealed the influence of biodegradation upon secondary settlement. Modern landfills, however, are designed with efficient containment systems which minimise moisture ingress and thereby reduce leachate and gas generation. The shortage of moisture means that these containment systems delay decomposition and stabilisation of waste. An altern...
Despite recent increases in recycling, composting, and incineration, the sanitary landfill remains the predominant and most economical municipal solid waste (MSW) management alternative. Modern MSW landfills strive to optimize the design, construction, and operation processes in order to mitigate many of the potentially negative impacts, and improve the profitability. The bioreactor landfill (B...
background: landfills are the most important producers of methane as human source. so, prediction of landfill gas generation is by far the most important concern of scientists, decision makers, and landfill owners as well as health authorities. almost all the currently used models are based on monod equation first order decay rate which is experimental while the main purpose of this research is...
The co-disposal of dewatered sewage sludge and municipal solid waste may cause significant impacts (such as total and differential settlement, slope stability of the waste, and leachability) on landfill operations and the subsurface environment. The objectives of this study were to investigate the co-disposal of dewatered sewage sludge and municipal solid waste with respect to their consolidati...
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...
