This study analyzes the amount of material deposited in Swedish municipal solid waste landfills, how much is extractable and recyclable, and what the resource and climate implications are if landfill mining coupled with resource recovery were to be implemented in Sweden. The analysis is based on two scenarios with different conventional separation technologies, one scenario using a mobile separ...

In bioreactor landfill, the leachate flow and moisture distribution depend upon saturated and unsaturated hydraulic properties of municipal solid waste (MSW). The effects of unsaturated parameters have not been studied because of scarcity of the data and variation in unsaturated parameters due to MSW heterogeneity, degree of decomposition, and pore structure. In this study, a numerical two-phas...

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...

Municipal solid waste landfills are significant parts of anthropogenic greenhouse gas emissions. The emission of significant amount of landfill gas has generated considerable interest in quantifying such emissions. The chemical composition of the organic constituents and potential amount of landfill gas that can be derived from the waste were determined. The chemical formulae for the rapidly bi...

A brief overview is given of the sources, characteristics, and toxic constituents of municipal solid wastes. Several methods are presented for handling, treating, and disposal of solid wastes. Monitoring the landfill site is necessary; there has been a trend to recognize that municipal solid wastes may be hazardous and to provide separate secure handling, treatment, and disposal for their dange...

Wind tunnel experiments have been carried out on a small-scale physical model of a municipal waste landfill (MWL) in the CRIACIV (Research Centre of Building Aerodynamics and Wind Engineering) “environmental” wind tunnel in Prato (Italy). The MWL model simulates a landfill whose surface is higher than the surrounding surface, applying a 1:200 scaling factor. Modelling an area source such as lan...

Bhopal is the capital and the second largest city of Madhya Pradesh. There is no arrangement for segregation of waste at source. It is a known fact that even elaborate Municipal Solid Waste Management (MSWM) schemes also fail. Hence people in MS WM activity schemes should design appropriate MSWM plan, water and landfill gas monitoring system.

Municipal solid waste (MSW) landfills are among the nation’s largest emitters of methane, a key greenhouse gas, and there is considerable interest in quantifying the surficial methane emissions from landfills. There are limitations in obtaining accurate emissions data by field measurements, and in characterizing an entire landfill with only a few such emissions measurements. This paper proposes...

Landfilling is one of the most widely used methods for the disposal of municipal solid wastes. The degradation of the organic fraction of the wastes in combination with percolating rainwater leads to the generation of highly contaminated liquid, called leachate. Municipal landfill leachates typically contain high concentrations of inorganic compounds (ammonium and metals), as well as high level...

The U.S. per-capita figure for garbage production has topped four pounds per person per day, and that amount is rising at roughly 5% per year. In the past, municipal solid waste was sent to the nearest local landfill or incinerator. But in 1988, the U.S. Environmental Protection Agency instituted the first federal standards for landfills, designed to make them safer. Over 10,000 small municipal...
