Formulating LandGem model for estimation of landfill gas under Indian scenario
Mostly in India, solid waste without any segregation is deposited into open dumping sites. Through these sites, there is uncontrolled emission of methane and landfill gas. The landfill gas has tremendous potential in terms of converting and using them as source of fuel. The emission of landfill gas depends on types of wastes, its rate of biodegradability, its methane potential, level of ...

Utilisation of landfill gas for the generation of energy
The gases in landfill sites that develop during degradation processes, largely contribute to the greenhouse effect and additionally harbour considerable safety and health hazards. However, they are also often rich in methane and therefore a potential energy carrier. In many countries much of this potential for the generation of electricity and heat from landfill gas still exists. Furthermore, ...

Compost as a landfill cover material for the elimination of methane emissions
Landfills, with about 40 - 60 Mio t emitted CH4 each year, are considered to be an important global source of the greenhouse gas methane. These emissions are especially caused by inadequate gas collection systems and uncontrolled emissions from old dumps and unauthorised open dumping. With traditional gas collection systems only 40 to 60 % of the produced gas can be collected and reused or safely ...

Utilisation of Municipal Solid Waste Compost as landfill cover soil for reducing greenhouse gas emission
Municipal Solid Waste Compost (MSW-C) was introduced for improving landfill cover soil properties and enhancing methane oxidation. The landfill cover soil was irrigated with leachate for maintaining appropriate moisture content for methane oxidation reaction. It was found that MSW-C was an effective landfill cover material for landfill gas emission control exhibiting the highest Methane Oxidation ...

Bord na Móna’s Drehid waste management facility - Case Study
The Irish Drehid Waste Management facility opened in 2008 to manage up to 360,000 tonnes of residual waste, including municipal, commercial and industrial waste. Bord na Móna has now taken its operations in this location one step further. The ‘Landfill Gas Utilisation Project’ was inaugurated in April 2014. After the landfill was up and running, Bord na Móna started ...

Low emission combustion of landfill gas
Type HOFGAS®- Efficiency 2000 (3x) Commissioning July 2002 Site Ämmäsuo Landfill (Espoo, FI) SituationÄmmässuo landfill is located in Espoo, about 20 km from Helsinki. The landfill is the largest one in Finland and one of Europe’s largest. In order to reduce the greenhouse gas emissions and eliminate odour problems in the vicinity, the temporary container plants were replaced with 3 ...

Greenhouse gas emission potential of the municipal solid waste disposal sites in Thailand
Open dumping and landfilling are the prevalent solid waste disposal practices in Thailand. Surveys on the disposal sites revealed the presence of 95 landfills and 330 open dumps. Methane emission potential at these sites was estimated by three methods. Results of the Intergovernmental Panel on Climate Change (IPCC) method, Landfill Gas Emission model (LandGEM), and closed flux chamber technique ...

New LFG Collection System Utilizes QED’s Revolutionary LFG Measurement and Control Technology - Case Study
“The main advantage, to me, is the Fine Tune™ Control Valve* that is used on the QED wellhead - it’s one of those revolutionary things in the landfill gas industry. Gate valves don’t give you very good control unless you always want the valve 100% open and you can apply as much vacuum as possible. But when it comes to low-flow wells then it’s important to be able to ...

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 ...

Actively aerated methanobiofilters to control methane emissions from landfills
Methane (CH4) capture at sanitary landfills for energy recovery is capable of reducing the impact of CH4 on the global atmospheric carbon budget. However, gas capture may only be viable where gas quantities are high enough to warrant economical energy production. Considering the potential global warming impacts, there is a need to identify alternative methods to control landfill CH4 emissions to ...

The use of methanotrophic applications to control of fugitive methane emissions from the biodegradation of organic waste
Large amounts of methane (CH4) escapes to the atmosphere through fugitive emissions arising from anthropogenic sources. This is detrimental because the Global Warming Potential (GWP) of CH4 is 25 times that of carbon dioxide (CO2) on a 100 year time horizon. As a result, there has been increasing interest in developing cost–effective and reliable alternatives for the minimisation of CH4 releases ...

A laboratory-scale comparison of compost and sand—compost—perlite as methane-oxidizing biofilter media
Municipal solid waste landfills produce methane, a potent greenhouse gas. A treatment approach is to passively vent landfill gas through a methane-oxidizing biofilter medium, a porous substrate that facilitates the growth of methanotrophic bacteria. Two substrates, compost and a sand—compost—perlite (SCP) mixture, were evaluated in a laboratory-scale experiment for their suitability as biofilter ...

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 ...
