  • Ontario Landfill Site - Case Study

    A Texas based company with waste management sites around North America have installed electrical generation plants at various locations that use methane collected from the waste. The daily operation of these sites include the management of the leachate, a liquid waste by-product of decomposition, and the collection of gas for electricity production. This is typically carried out at multiple wells ...

  • Landfill sites – home to buried treasure!

    Recent studies have found that landfill sites are most certainly filled with huge volumes of valuable metals. According to a study carried out by Cranfield University, scientists analysed samples from up to 30 metres deep from four different landfill sites. Large objects where removed and the samples were analysed for the content of rare earth metals and other valuable metals. Results indicated ...

  • Raffen landfill site, Cork, Ireland

    AFS were awarded a contract to design a gas and leachate collection system, and carry out a 10-week gas pumping trial to evaluate the levels of gas being generated from Raffen Landfill Site. From the pumping trial data, a 200m3/hr HT flare was designed, built and installed. A hydrovane compressor/receiver/dryer package was installed to operate ten pneumatic leachate extraction pumps. Within ...

  • Assessment of landfill gas and methane emission at Keru landfill site, Jodhpur (India)

    Jodhpur is densely populated and urbanised city of Rajasthan state. The population of the city is considerably increased in past few decades due to rapid urbanisation and industrialisation within the city. Presently inhabitants of Jodhpur generate about 392 t/d of MSW. MSW management has remained one of the most neglected areas of the municipal systems. About 70–80% of generated MSW is collected ...

  • Landfill site improvement condition for PPC permit

    The installation is a landfill site licensed for the disposal of inert waste. It lies in a potentially sensitive location on the flood plain of the River Great Ouse, near Milton Keynes and it is therefore important to the client to ensure good environmental monitoring is undertaken. The site is divided into two sections, (the north western area and the south eastern area) by the River Great Ouse, ...

  • Landfill site selection by using geographic information systems

    Abstract  One of the serious and growing potential problems in most large urban areas is the shortage of land for waste disposal. Although there are some efforts to reduce and recover the waste, disposal in landfills is still the most common method for waste destination. An inappropriate landfill site may have negative environmental, economic and ecological impacts. Therefore, it should be ...


  • Modeling Leachate Contamination and Remediation of Groundwater at a Landfill Site

    Leachate contamination of an aquifer from a landfill sitewas simulated using the groundwater flow and transport model SUTRA developed by the U.S. Geological Survey. The model calibration was performed by spatially adjusting the hydraulic conductivity in order to capture the measured hydraulic head spatial variation and then by adjusting the dispersivity and porosity match the measured chloride ...

  • An expert system on site selection of sanitary landfill

    It is desirable to encapsulate heuristic and empirical knowledge including hydrological and bio-geochemical considerations into the selection process of a potential landfill site. This paper delineates a prototype expert system, which has been developed using a commercially available microcomputer-based expert system shell VISUAL RULE STUDIO, for the selection of a landfill site. VISUAL RULE ...

  • Inox in a landfill

    For collection and transport of leachate, landfill sites are using various types of pumps. Grindex electrical corrosion resistant pumps provide the volume needed where pneumatic pumps and other submersibles pumps fall short. One of the landfills in Illinois has 18 Grindex corrosion resistant pumps in operation and they now have plans to replace all remaining submersibles with Grindex INOX pumps. ...

  • Predicting the site water balance of a phytocapped landfill using HYDRUS 1D

    An alternative landfill capping technique called 'Phytocapping' was trialled in Rockhampton, Australia. In this technique, trees were used as 'bio-pumps' and 'rainfall interceptors' and soil cover as the 'storage' of water. The performance of this system was measured based on its ability to minimise water percolation into waste. The percolation rate was modelled using HYDRUS 1D for two main ...
