The municipal solid waste landfill as a source of Montreal Protocol-restricted halocarbons in the United States and United Kingdom
… United Kingdom (UK) from municipal solid waste (MSW) landfills. With several hundred MSW landfills in both the US and UK, estimating emissions of MPGs from landfills required a targeted approach. Whole landfill mixing ratios and flow rates were sampled monthly at one landfill in southern …

The status of wood pallet disposal and recovery at united states landfills
… number of wooden pallets are disposed of in US landfills, representing a significant portion of total wood usage. The purpose of this research was to gain an understanding of the numbers of pallets reaching landfills, specifically Municipal Solid Waste (MSW) and Construction & Demolition (C&D) …

Elevated temperatures in waste containment facilities
Municipal solid waste (MSW), construction demolition debris (CDD), industrial byproducts, and many other wastes are landfilled in waste containment facilities. A number of factors can lead to elevated temperatures and thus present a hazard to the public health and safety. For instance, MSW …

Monitoring and Inverse Dispersion Modeling to Quantify VOCs from MSW Landfill
In USA, the Municipal Solid Waste (MSW) landfills accumulate about 130 million tons of solid waste every year. A significant amount of biodegradable solid waste is converted to landfill gas due to anaerobic stabilization by bacteria. These biochemical reactions produce volatile organic compounds …

Carbon Nanotube Behavior in Represntative Old Leachate
… being discarded in municipal solid waste (MSW) landfills. Many commonly discarded products have been reported to contain nanomaterials, including plastics, ink jet printer paper, textiles, cosmetics, sunscreens, and sporting goods. Although no direct measurement or inventory of nanomaterial …

Long-Term Performance of HDPE Geomembranes as Landfill Liners
… facilities such as municipal solid waste (MSW) landfills and heap leach pads. Field conditions, which include physical stresses on the geomembrane, elevated operating temperatures, and contact with leachate constituents, have the potential to affect the service life of the HDPE …

Facultative Bioreactor Landfill: An Environmental and Geotechnical Study
… as bioreactor landfill technology. Bioreactor landfills are sanitary landfills that use microbiological processes purposefully to transform and stabilize the biodegradable organic waste constituents in a shorter period of time. One of the most popular types of bioreactor landfills is the …

An investigation of recalcitrant organic compounds in leachates
… treated leachate samples collected from two UK MSW landfills (Pitsea and Rainham), and leachates are characterised using conventional methods (COD and DOC) as well as UV absorption and fluorescence spectroscopy. It is found that the leachates which have low organic content are easily …

Comparative Assessment of Single & Double Interface Shear Strength Properties: A Case Study of a Landfill Project in the Western Cape Province, South Africa
… stipulated inclusions in municipal solid waste (MSW) landfill's lining systems as they provide a competent hydraulic barrier, limiting environmental pollution and protecting public health. While these inclusions have considerable cost and technical benefits, they have presented several new …

Evaluating Leachability of Residual Solids Generated from Unconventional Shale Gas Production Operations in Marcellus Shale
… either buried on site or are disposed in lined landfills. The objective of this study was to determine the levels of heavy metals and other elements of concern that will leach from these residual solids when placed in typical disposal environments. For this purpose, laboratory leaching …

An investigation into the impact of sequential filling on properties of emplaced refuse lifts and moisture stored in a municipal solid waste landfill
… of investigations on municipal solid waste (MSW) landfills have been undertaken during the post-closure period, and therefore, the changes that occur in the properties of refuse layers placed during the period of infilling are often ignored. The impact of further tipping of refuse loads on …

Modern landfill leachates – quality and treatment
… 10 % have diverted large amounts of waste from landfills. The biogeochemistry of landfills has changed due to their reduced organic content. The research presented in this thesis aimed at improving understanding of leachate quality in modern landfills. Biodegradation and leaching tests were …

Investigation of Temperature, Solution Strength, and Applied Stress Effects on Cation Exchange Processes in Geosynthetic Clay Liners
… behavior of Na-B GCLs in municipal solid waste (MSW) landfills and laboratory testing applications. Needlepunched-reinforced, double non-woven Na-B GCL specimens were conditioned in fluids of increasing ionic strength (DI water, 2 mM CaCl2, 50 mM CaCl2, and 200 mM CaCl2 representing control, pore …

Development of a technical management tool for settlement and stability behaviour of municipal solid waste landfills
… method of disposal of municipal solid waste (MSW). Landfills are engineered structures consisting of bottom liners, leachate collection and removal systems, and final covers. With an expanding world and the remarkable growth of industry, the demand for larger and higher capacity landfills is …
