Environmental and Economic Evaluation for Biogas Generation in Jordanas a Greenhouse Gas Mitigation Option

Abstract

Reduction of Landfill Gases (LFG) positively affects the environment because they contain greenhouse gas emissions like CO2, CH4 and other trace gases. Therefore, one of the solutions to mitigate the climate change impacts is using landfill recovery system. Al-Ghabawi Landfill was chosen as a case study and the model used to predict the amount of landfill gases generated from the landfill is based on the IPCC (Intergovernmental Panel on Climate Change) default method. The estimation was based on quantification of waste quantities and components. Preliminary economic study was made to evaluate the feasibility of constructing power generation plants over the lifetime of the proposed project by assuming a case of using landfill gas recovery and a case without integrating any landfill gas. This study found that the Landfill gases utilization in landfills is considered satisfactorily enough both in electric energy production and in mitigating greenhouse gases.
