Tecnologia para reaproveitamento de rejeitos orgânicos para geração de energia

Abstract

Human and animal waste as a source of renewable energy is emerging as a new way to solve one of the major environmental problems faced by municipalities. In the urban area, human waste needs to be directed and treated because it is the main cause of sanitary diseases. In the rural area, animal waste can be used as biofertilizers and for the production of biogas for reuse in ovens. While biokerosene is configured as a trend to replace kerosene from oil in aviation, it still needs advances to minimize production costs. In order to construct a reflection on the subject, this work has as object of study the simulated development of a new technology for processing waste for the production of biodiesel and biofertilizer, which may also produce biokerosene. The general objective was to simulate the operation of the process. To build this analysis we developed two specific objectives: a) to build the equipment of the study process b) to simulate and validate the process. The results show that this project presents a great economic viability, being possible to separate from the sewage, on a large scale, oils necessary for the production of biofuels, industrial water and biofertilizer. This technology was developed for processing on a macro scale, where investment and operating costs are high; however, it can be improved for construction on a commercial scale, with lower costs and productivity.
