The effect of high organic liquid wastes on the overall performance of anaerobic bioreactor landfills is not known. In this study three different liquid wastes were added to mix of office paper, newspaper, cardboard and plastic in 3 different concentrations under anaerobic conditions to determine their effect on degradation of organics. The addition of buffer chemicals was found to improve degr...

Representative dynamic properties of municipal solid waste (MSW) are required to perform reliable seismic analyses of MSW landfills. A comprehensive large-scale cyclic triaxial laboratory testing program was performed on MSW retrieved from a landfill in the San Francisco Bay area to evaluate the small-strain shear modulus, and strain-dependent normalized shear modulus reduction and material dam...

In the landfills of municipal solid wastes there are a number of constituents which will leach under the influence of infiltrating water. Among the leached constituents there are also trace inorganics which are potentially hazardous to the environment, the most important being the heavy metals. It follows that the waste landfills have a high contamination potential in terms of heavy metals, bec...

hydrologic evaluation of landfill performance (help) model is one of the most accepted tools to simulate the hydrological attributes of landfills. although some major deviations from real values has been reported about the calculated results for leachate generation by help model but other researchers and/or engineers in practice have used it in some places to estimate amount of leachate produce...

BACKGROUND Management of solid waste (mainly landfills and incineration) releases a number of toxic substances, most in small quantities and at extremely low levels. Because of the wide range of pollutants, the different pathways of exposure, long-term low-level exposure, and the potential for synergism among the pollutants, concerns remain about potential health effects but there are many unce...

Landfilling, as a system to discard municipal waste, is still widely used in the tropics, often without appropriate protection against pollution of its surroundings. Leachate generation from landfills, and its chemical composition, varies widely and is significantly influenced by landfill geometry, the type and age of waste, seasonal precipitation, moisture and temperature. In the tropics, clim...

5 A considerable amount of solid wastes is generated every year from construction and demolition (C&D) 6 activities in Hong Kong. The C&D waste can be classified into inert and non-inert wastes, in which the 7 inert waste is normally disposed of in public fills as reclamation materials, and the non-inert part is dumped 8 at landfills. Under the current waste generation trend, all landfills and ...
