APPROPRIATE TECHNOLOGY FOR LANDFILL METHANE GAS EXTRACTION FOR ELECTRICITY GENERATION AND EMISSION REDUCTION

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...

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 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...
