Bioetanol a partir de los residuos de frutas y verduras de los mercados de Calceta y Quiroga

The objective of this research was to obtain bioethanol from waste such as fruits and vegetables from the markets in Calceta and Quiroga. It was developed in a randomized block design with three treatments and four repetitions that respectively generated 12 experimental units. Each treatment consisted of 5,67 ml of yeast (Saccharomyces cerevisiae), 0,50 dm3 of molasses and 1,81 g of urea. Treatment one (T1) was made up of fruits, treatment two (T2) of vegetables and treatment three (T3) of fruits and vegetables. Fruits and vegetables were collected for 2 weeks, once the raw material collection and preparation of the experimental units were finished, the anaerobic fermentation process of each treatment was started for eight days following the specifications of Pari (2013). Finally, it was possible to obtain bioethanol from fruits and vegetables, with T1R4 being the treatment with the highest degree of alcohol, with a value of 39% of which 2668 ml was obtained. According to the degrees of alcohol obtained, by means of Tukey's analysis of variance through the SPSS version 20 program, the hypothesis raised in the research is accepted. The economic analysis of the best treatment using the cost of production method determined a value of $2,75 for each dm3 of alcohol. In conclusion, the production of bioethanol from these wastes is economically feasible, since it promises the concrete perspective of a more sustainable energy reality.
