  <dc:description>A large amount of coffee waste water is generated from coffee processing plants. These
residues possess serious environmental problems following the direct discharge in to the
nearby water bodies and cause serious environmental and health problems. This study
aimed to: (i) review wet coffee processing waste management practice in Ethiopia, (ii)
characterize wet coffee processing waste and determine its total reducing sugar potential,
(iii) quantify wet coffee processing waste and estimate its bio-ethanol potential and also
evaluate the feasibility of bio-ethanol production and (iv) optimize the parameters and
produce bio ethanol from wet coffee processing waste. The review of wet coffee
processing waste management practice in Ethiopia revealed that there are about 1026
operational wet coffee processing industries and many more industries are under
construction. In 2012, the estimated amount of wet coffee processing waste from
operational industries in Ethiopia was about 291,600 tones / year. The study also
examined the characteristics of wet coffee waste</dc:description>
