Obtención de Etanol a Partir de Residuos Orgánicos de la Sección de Frutas del Mercado Mayorista de Riobamba

Abstract

The objective of this research was to obtain ethanol from the organic residues of the fruit section of the San Pedro de Riobamba Wholesale Market between August and September 2007, in order to use it as a fuel to replace petroleum derivatives: Moisture, ash, protein, phosphorus, potassium, total sugars, reducing sugars, non-reducing sugars, fiber, starch, total mesophilic aerobes, total coliforms, fecal coliforms, molds and yeasts. 2nd. Process of obtaining ethanol using 4 treatments (T1, T2, T3, T4). 3rd. Analysis of the data obtained, by means of a statistical analysis. It was determined by applying a Tukey test at 95% confidence level using STATGRAPHICS PLUS software, that the treatment with the highest yield was T4, in which 0.07525 L/ethanol of 950 is obtained from 1.5 kg of residues at a cost of $0.80/L at laboratory level, obtaining a product suitable for use as fuel. It is recommended to carry out studies to determine other alternative uses for these wastes and the feasibility of implementing the process at industrial level.
