Production of bioethanol from mucilage of coffee (Coffea arabica. L). CURC. UNAH. Comayagua. Honduras. 2011

Abstract

Getting ethanol from coffee mucilage, which is a waste product that is thrown into running water, without treatment, because the producer has no alternative use, causing serious pollution problems. The study details about the use of mucilage produced during the milling process of the fruit, being the study sites in La Libertad, Comayagua Department and Marcala, La Paz Department. The two fermentation methods used are: in the controlled method were inoculated three samples, each with different brix degrees of 2000 milliliters of mucilage +2% Weight / Weight, 2000 ml of mucilage +4% weight / weight and 2000 ml of mucilage +6% Weight / Weight of Saccharomyces cerevisiae and the method controlled without inoculation of yeast, which were used in three samples of 2000 milliliters with different Brix degrees. For each of the methods 800 milliliters were distilled doing two repetitions of each of the samples.

The analysis shows that there are factors that influence to obtain satisfactory yields: height, concentration of sugar, coffee processing and inoculation methods, among others. This also aims to raise institutions involved in rural extension and coffee producers in the implementation of bioethanol as alternative energy source as fuel for cars and other uses of human benefit, while responding to the environmental problem representing the wastewater of coffee (mucilage) in different parts of our country.
