  • 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 ...

  • Application of a novel sampling bailer device for the analysis of dissolved methane concentrations in municipal wastewater during and following anaerobic treatment

    Modern wastewater utilities need to be able to measure and quantify the amount of methane from their treatment facilities in order to understand the potential energy that can be produced and the amount of methane being lost. This paper describes the application of a novel sampling bailer designed for the collection of wastewater samples that minimises methane losses. Samples collected during ...

  • Methane emissions reduction from organic wastewater and solid waste co-composting: parameter estimation and sensitivity analysis

    Using the approved large scale methodology AM0039 and approved baseline methodology AM0010, an estimated 7,329.04 tCO2e/yr are typically generated from degradation of organic wastes at the landfill in Mauritius. Baseline emissions for anaerobic degradation of organic wastewaters (OWW) in open lagoons approximated to 36,036 tCO2e/yr; 402,783.92 tCO2e/yr for transportation of OWW and municipal ...

  • Energy and exergy analyses of a steam reforming process for hydrogen production

    Hydrocarbon steam reforming is an important process for hydrogen production. In petroleum refineries, steam reforming is most commonly used for hydrogen production from naphtha and light hydrocarbon gases (methane, ethane and propane). Since the hydrocarbon steam reforming system is one of the highest energy intensive systems in a petroleum refinery it should be directed to a more efficient use ...

  • Silent sentinel role for static gas analyser at United Utilities

    Biogas produced by the United Utilities anaerobic digestion sludge plant at Lancaster (Stodday) waste water-treatment runs a brand new 525kW combined heat and power (CHP) engine generating electricity and now operating 24/7. It joins an existing 325kW engine already in service for three years. In addition to biogas from the Stodday mesophilic anaerobic digester, a new enzymic hydrolyser increases ...

  • Solid waste management in Patna – analyses of ambient air and ground water pollution

    Municipal Solid Waste (MSW) in Patna is disposed of in an unscientific manner without considering environmental impacts. The wastes are dumped in the low-lying areas without compliance of the MSWM Rules, 2000. The dumped wastes are mixed with biomedical wastes making it hazardous. Ambient air quality and ground water were analysed at two dump sites to study the possible impacts of MSW. The ...

  • Production of methane gas from organic fraction municipal solid waste (OFMSW) via anaerobic process: application methodology for the Malaysian condition

    Solid waste management in Malaysia is confronted with many problems, including low collection coverage, irregular collection services, inadequate equipment used for waste collection, crude open dumping and burning without air and water pollution control systems, inadequate legal provisions and resource constraints. These problems have various effects on the development of the solid waste ...

  • Spatial and short-term temporal distribution of fugitive methane and nitrous oxide emission from a decentralised sewage mining plant: a pilot study

    The decentralisation of wastewater treatment operations exposes several environmental consequences. This includes the fugitive emission of two greenhouse gases, nitrous oxide (N2O) and methane (CH4). The magnitude of these emissions is presently unclear. Therefore, it is necessary to measure the extent of the release of N2O and CH4 gas from decentralised wastewater ...
