This study aimed to quantify the wet coffee processing waste and estimate its bio-ethanol potential in Ethiopia and also evaluate the feasibility of bio-ethanol production from wet coffee processing waste. Green coffee production in Ethiopia is increasing from year to year (from 2007 to 2012) and reached 5.6% of world production. There are about 1026 operational wet coffee processing industries and many industries under construction in Ethiopia. In 2012 the estimated amount of wet coffee processing waste from operational industries in Ethiopia is about 291,600,000 and more waste will add up when the industries under construction become functional. Lingo-cellulosic biomasses with the large amount of glucose convertible material are potential feedstock for bio-ethanol production. Lignocellu-losic biomass feeds are a highly available, cheaper alternative to corn for use as feedstock for the production of ethanol. These feeds are reliable and sustainable and provide a source for fuel to meet the needs of society and contribute to energy security in an increasingly environmentally sound manner
