Selección de la alternativa tecnológica más apropiada para el aprovechamiento de las borras del aceite vegetal usado que se generan en el proceso de filtración, para la posterior elaboración de biodiesel de segunda generación

Abstract

After the appliance of resolution 0316 of 2018, is necessary a solution for the disposal and management of used vegetable cooking oil, as an alternative for use it is used for the production of second generation biodiesel. However, the filtration of the AVU in the exploitation plants, produces a sediment that is discarded in the process for the production of biodiesel and cannot be disposed in sanitary landfills or discharged as wastewater. Under technical, economic, environmental and social attributes, the optimal technology was evaluated through the Index of Appropriate Technology for the Improvement of Soapstock defined in this document as a weighted geometric average. Among the alternatives for use as pet food, cement production and brick making, biogas production, soil improvement, asphalt manufacture and soap production, soil improvement was chosen due to the suply of higher index and 100% use.
