In situ aeration by means of the Airflow technology was proposed for landfill conditioning before landfill mining in the framework of a reclamation project in Northern Italy. A 1-year aeration project was carried out on part of the landfill with the objective of evaluating the effectiveness of the Airflow technology for landfill aerobization, the evolution of waste biological stability during a...

The selection of a landfill site is considered as a complicated task because this process is based on many factors and restrictions. For Al-Qasim Qadhaa, which is situated in the southern part of the Babylon Governorate, Iraq, there is no landfill site in that area that conforms to the scientific criteria for selecting sites for landfill. For this reason, 15 criteria were adopted in this study ...

Many landfill siting reports, of which those of the Franklin County, OH, landfill are typical, imply continuity of minor sand bodies in till between widely-spaced test holes where sand deposits fall within similar depth ranges. This review of studies of the local origin of most sand and gravel "lenses" or "seams," and their transport in active glaciers, however, indicate that most such deposits...

The details of a semi-aerobic landfill type are described and compared with an aerobic landfill type, particularly related to the characteristics of the solid waste stabilization and the stabilization mechanism. Semi-aerobic landfill is an attempt to lay the leachate collection pipe, comprising the perforated main and branch pipes and gravel, at the bottom of the landfill to discharge leachate ...

Percolate production and precipitation data for a full-scale landfill in operation measured over a 13-year period were used to evaluate the impact and importance of the hydrological conditions of landfill sections on the percolate production rates. Both active (open) and closed landfill sections were included in the evaluation. A simple top cover model requiring a minimum of input data was used...

There is considerable interest today in the so-called “biocell” approach toward municipal solid waste (MSW) landfilling in which leachate is introduced back into the landfill. This approach reduces the cost of leachate management and is said to reduce/eliminate the potential for long term landfill gas production and groundwater pollution. However, a critical review of the typical approach being...

Due to irregular and uncontrolled expansion of cities in developing countries, currently operational landfill sites cannot be used the long-term, as people will living proximity these exposed unhygienic circumstances. Hence, this study aims at proposing an integrated approach for determining suitable locations landfills while considering their physical expansion. The proposed utilizes fuzzy ana...

The Australian Community Psychologist Volume 20 No 1 June 2008 The number of separate kerbside dryrecycling and organic waste collection systems operated by UK Local Authorities (LAs) has risen sharply as a result of the implementation of the European Landfill Directive (99/31/EC) into UK legislation on the 16th July 2001, concerns over remaining available landfill void space, and statutory rec...

The microbial conversion of lignocellulosic biomass for biofuel production represents a renewable alternative to fossil fuels. However, the discovery of new microbial enzymes with high activity is critical for improving biomass conversion processes. While attempts to identify superior lignocellulose-degrading enzymes have focused predominantly on the animal gut, biomass-degrading communities in...
