Landfill Settlement with Decomposition and Gas Generation

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...

Estimation of landfill gas generation in a municipal solid waste disposal site by LandGEM mathematical model

Anaerobic decomposition of organic compounds in landfills is responsible for generation of greenhouse gases. The present study aimed to determine the total gas and methane emission from a landfill located in Hamedan (west of Iran) from 2011 to 2030. LandGEM 3.02 model was used to estimate the gas emission with the volumetric methane percent of 60%, production potential of 107, and methane gener...

Landfill Gas Migration Modelling – a Prequiste for Determining Environmentally Compatible Gas Generation Rates

SUMMARY: Landfills containing organic matter pose an environmental risk for many decades. This is also the case for the landfill Heferlbach, which has been filled until 1974 with more than 200,000 tons of waste. Since no liners have been installed at this site, landfill gas generation represents a potential hazard to the surrounding environment. In particular, the risk for methane migration int...

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...
