  • Case study - Monitoring landfill gas

    Infrared absorption Infrared absorption is usually the preferred method for measuring methane and carbon dioxide. Most gases absorb radiation in the infrared region. The wavelength of radiation that is absorbed is determined by the natural vibration frequencies of the molecule. These natural frequencies will depend on several factors. Thus different gas molecules have different natural ...

  • 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 ...

  • The importance of maintaining your fixed gas analyser

    Plant technicians rigorously check for contaminates within the digester and ensure that the performance is optimised but maintaining the gas analyser monitoring the whole process is often overlooked.  Many analysers are used in harsh and potentially explosive environments and so it is of paramount importance that the operation runs smoothly and safely. With simple maintenance of your ...

  • Why high temperature combustion of landfill gas?

    Due to the accumulation of knowledge and the tightening of environmental law, the landfill technology has increasingly become concerned with the management of trace compounds in landfill gas. With landfill gas, contamination is through sulphur, chlorine, fluorine, halogenated hydrocarbons and heavy metals. Other trace elements such as volatile organic compounds (VOC), impose environmental ...

  • Gas analysers support management of Swindon fire

    The capability to convene a multi-agency Air Quality Cell (AQC) was established in England in 2009 following the Buncefield Oil Storage Depot incident. A review of this event identified the need to rapidly co-ordinate the acquisition, analysis and interpretation of air quality data in major incidents. Arrangements have been made in England to bring together experts from the Environment Agency ...

  • Measuring and interpreting gas flow from landfill boreholes case study

    Current landfill gas measurement practice for measuring the gas composition is well understood, and there are standard procedures and instruments available to analyse the gas. It is also current recognised practice to measure the gas 'flow' from boreholes to monitor the production of gas in a landfill site. If care is taken to make the measurement in the same way each time, changes in the ...

  • Modified landfill design for sustainable waste management

    Waste management, being one of the most important aspects of urban development, is gaining importance among developing nations. Landfills, which were initiated for hazardous waste management and subsequently transformed into sanitary landfills, have been the most widely adapted practice for municipal solid waste management worldwide. However, the conventional design of landfills not only fails to ...

  • Effects of landfill leachate treatment on hepatopancreas of Armadillidium vulgare (Crustacea, Isopoda)

    The major environmental impact to the landfill is emission of pollutants via the leachate and gas pathway.The hepatopancreas of the terrestrial isopod Armadillidium vulgare (Isopoda, Crustacea, Latreille 1804) takes an important role in bioaccumulation of contaminants, such as heavy metals. To evaluate the effects of landfill leachate treatment, two different approaches are here applied: 1) ...

  • Remediation of MSW landfill leachate by permeable reactive barrier with vegetation

    This research was conducted to investigate in situ treatment of leachate by pilot-scale permeable reactive barrier (PRB) with vegetation. Two different types of PRB media, with and without the presence of ferric chloride sludge, for the removal of pollutants were examined. The composite media of PRB comprised a clay and sand mixture of 40:60%w/w (system 1) and a clay, ferric chloride ...

  • Europe’s objective: recycle more waste and send less to landfills

    Is waste a problem or a resource? Waste is both, depending on what we do with it. It is a problem because it can affect people’s health and the environment. For example, landfills are an important source of methane emissions, which is a powerful greenhouse gas contributing to climate change. Run off from landfills can contaminate ground waters and soil, which can then enter the food ...
