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