  • Effect of chloride concentration on nitrogen removal from landfill leachate in sequencing batch reactor after MAP pretreatment

    Leachate generated from landfill is becoming a great environmental challenge to China as it contains high concentration of COD, ammonium and some other substances. Nitrogen removal through the conventional nitrification-denitrification process is hampered by the low C/N ratio especially for the old age landfill sites and the high energy consumption for aeration. In this study, the combination of ...

  • England’s new recycling road map

    In the introductory comments to the 124-page ‘Waste strategy for England 2007’, the government’s Department for Environment, Food and Rural Affairs (DEFRA) hails ‘major progress’ in recycling rates since the year 2000 but immediately counters with the assertion that England’s performance on waste ‘still lags behind many European countries’.  Designed to be a road map highlighting the ...

  • 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 ...

  • Enhanced waste-management practices reduce carbon emissions and support lower landfill taxes

    Landfill taxes and ‘enhanced waste management’ practices have been introduced to reduce the amount of waste that goes to landfill and to convert waste into useful products. This study investigated the interplay of these two policy options in Belgium, generating findings that could help Europe move towards a resource-efficient, circular economy. Landfill taxes and ‘enhanced waste ...

  • Integrated Geophysics: Magnetic / EMI surveys at an air force base

    PROJECT: EMI and Magnetic surveys at closed waste disposal sites LOCATION: Holloman Air Force Base near Alamogordo, New Mexico PROJECT DESCRIPTION: Designed and performed total-field magnetometer surveys in tandem with EM-31 terrain conductivity (EMI) surveys of approximately 53 acres of closed landfills at an Air Force base in New Mexico.  Survey ...

  • Field Demonstration of a Permeable Bioreactive Barrier for Leachate Control.

    ABSTRACT: A biostimulation technique was selected for a pilot study to treat groundwater at a former New Jersey municipal landfill. The process will address a mixture of chlorinated compounds (e.g. vinyl chloride and chlorobenzene), hydrocarbons (e.g. benzene and methyl ethyl ketone) and heavy metals. The reactive barrier will be constructed using a series of injection points to implace a slurry ...

  • Maesteg Row, South Wales case study - A former gas works proves larger than originally thought

    An old gas company sold land to Maesteg Rural District Council for social housing in the 1970s. Although the land had been sold, improved historic data has indicated the gasworks site was much larger than originally thought – and nearer to residential housing. British Gas inherited the site, and as part of maintenance programme undertook ‘stabilisation work’ – investigating potential pollutants ...
