Propuesta del diseño de un biodigestor a partir de la evaluación energética de los RSO de cinco restaurantes

Abstract

In the development of this project are identified the highest production of the MSW (Organic solid waste) in the restaurants around the Universidad Distrital Francisco José de Caldas – Facultad Tecnológica, Finding the greater presence of banana and potato peels, with which are evaluate the possibility to get biogas and using it as a biofuel inside Facultad Tecnológica. With these residues are made combinations with different percentages concentration, and rumen is added as inoculum. It is choose the higher biogas production combination at controlled temperature and environment temperature. The best results are achieved with the combination of 50% and 50% of the residual biomass treated at environment temperature, (20 ° C) followed by the combination of 75% potato peel and 25% banana peel, treated at 30 ° C. It is evaluate the energy efficiency, achieving values of 45% and 53.8% respectively. Retention times were 55 days for the two mixtures. With this information is formulated the design of a semi-continuous flow biodigester to be loaded every 2 or 3 days, and the proposed location is next to the gas stove in the kitchen of the cafeteria of the Facultad Tecnológica.
