Specific model for the estimation of methane emission from municipal solid waste landfills in India.

Abstract The landfill gas (LFG) model is a tool for measuring methane (CH 4 ) generation rates and total CH 4 emissions from a particular landfill. These models also have various applications including the sizing of the LFG collection system, evaluating the benefits of gas recovery projects, and measuring and controlling gaseous emissions. This research paper describes the development of a landfill model designed specifically for Indian climatic conditions and the landfill’s waste characteristics. CH 4 , carbon dioxide (CO 2 ), oxygen (O 2 ) and temperature were considered as the prime factor for the development of this model. The developed model was validated for three landfill sites in India: Shillong, Kolkata, and Jaipur. The autocorrelation coefficient for the model was 0.915, while the R 2 value was 0.429.
