ENGINEERING PROPERTIES OF MSW LANDFILL DAILY COVERS USING WASTE TIRE CHIPS AND PAPER SLUDGE

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 …

A DIFFERENT GAS GENERATING REGIME WITHIN LOW-CARBON WASTE LANDFILLS IN THE UK AND EUROPE

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 …

ENERGY RECOVERY OF BIOGAS GENERATED IN LANDFILLS FOR MANUFACTURING HIGH QUALITY CERAMIC PRODUCTS

The project focus on using the biogas, produced in the Can Mata landfill, as an alternative fuel source in a ceramic factory. This is the first application of this technology in Spain, and one of the first experiments of its kind in Europe. The new process design means that 83% …

“END-OF-THE-PIPE” MATERIAL RECOVERY TO REDUCE WASTE DISPOSAL AND TO MOTIVATE THE INFORMAL SECTOR TO PARTICIPATE IN SITE IMPROVEMENTS AT THE CALAJUNAN DUMPSITE IN ILOILO CITY, PANAY, PHILIPPINES

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. …

LANDFILL GAS (LFG) FUGITIVE EMISSIONS ON LANDFILL SURFACE – COMPARATIVE TEST OF ON SITE ANALYSIS DEVICES

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 …
