Landfill Gas and Temperature

Characterization of Landfill Sites in Brazil for Landfill Gas Recovery

Beneficial Use of Landfill Gas

1 page only) With regulatory and environmental pressure toward control of landfill gas (LFG) management of collected LFG has become a significant issue. At a minimum, collected LFG must be flared for control of methane and nonmethane organic compounds. Beneficial reuse of LFG as an alternative to combustion has tremendous potential at most landfills. Issues facing reuse of LFG include gas compo...

Estimation and modeling of gas emissions in municipal landfill (Case study: Landfill of Jiroft City)

One of the major factors, contributing to the emission of greenhouse gases in the environment is generation of pollutant gases in municipal landfills. As for the design and building of a gas collecting system, it is necessary to properly estimate the amount and type of the landfill emissions. By means of LandGEM model, this study predicts the amount and type of the landfill gases, produced for ...

Landfill Settlement with Decomposition and Gas Generation

A one-dimensional multiphase numerical model is developed to simulate the vertical settlement involving liquid and gas flows in a deformable settling municipal solid waste MSW landfill. MSW is represented by a chemical composition, and a global stoichiometric reaction is used to estimate the maximum yield of gas generation. Following the general assumption accepted in the literature, the gas ge...

Combined Landfill Gas and Leachate Extraction Systems

There is currently a shift of emphasis in the approach to treatment of landfill gas and leachate. Until recently, there have been two disparate schools of thought concerning the collection and disposal of these two by-products of organic waste degradation within the same bio-reactor. The tendency in the past has been to study gas and leachate as separate problems each of which requiring a separ...
