Waste management problems in developed countries differ from those in developing countries. Whereas the former have access to the needed financial and technical resources as well as expertise and a well developed market, the latter countries struggle to provide basic systems to manage waste such as a waste collection system. …

The use of earth materials as daily covers not only consumes valuable landfill space, but also brings a series of operating issues such as fine migration and hetergenity of waste mass. In this study, a mixture of paper sludge and waste tire chips was proposed for daily cover applications in …

ISSeP has been controlling for ten years the gaseous and liquid emissions of main landfills in Wallonia. The monitoring of landfill surface gas-emissions is usually performed with portable FID analysers. Such devices offer high sensitiveness but measuring ranges are sometimes too short for high methane concentration. It is why another …

In low carbon waste landfills the availability of water or a carbon source, or the build up of toxic compounds appears to limit anaerobic gas generation. Thus oxygen consuming chemical/biological reactions occur immediately after the waste is placed, but factors required for anaerobic degradation become exhausted, perhaps because of limited …

In order to quantify and compare the environmental impacts caused by several modern household waste management strategies in the federal state of Baden-Württemberg, Germany, the Life Cycle Assessment (LCA) cradle-to-grave analysis, which accounts for the material and energy flows during the life cycle of a product or service, has been …
