Feasibility Analysis of Biogas Production by Using GIS and Multicriteria Decision Aid Methods in the Central African Republic

Organic waste-derived biogas production is an effective way to transform biowaste into renewable energy for the electricity supply in developed and developing countries. This study analyzes feasibility of as a solution waste management Bangui, capital city Central African Republic. The selection plant site urban area complex process due availability different factors. GIS, combined with MCDA, could analyze environmental, social, economic factors criteria such slope, settlement, rivers, land, growth, local major roads. Applying ELECTRE TRI MCDA method enhanced techniques determine suitable site. amount distance from were determined using ArcGIS toolset. plant’s environmental benefits, capacity CO2 reduction, analyzed based on population growth per year. results obtain 3.5 km2 large-scale construction, potential 2,126,799.68 kW year heat power 2,303,100.23 by converting thermal electricity. treat 20% organic year, cover 60% city’s demand, reduce 946,200 kg equivalent
