Avaliação técnico-econômica da produção de energia elétrica e biofertilizante sólido a partir de dejetos suínos

Abstract

The constant growth in the use of electricity has been one of the biggest concerns in view of the increase in the world population. So as a premise for solutions, the growth of sustainable sources of electricity generation is notorious. In the same way, for the same reason land suitable for cultivation is becoming less and less productive, requiring supplementation of nutrients. Therefore, the present project has the goal to produce electricity and organic biofertilizer from swine manure produced on a private property located in western Santa Catarina, which is one of the largest swine productions in the country. To make sustainable use of the potential of the farm with the residues of the process of raising pigs, supplying the demand of the property regarding the electric energy that will be produced as well as the local commercialization of the organic biofertilizer. Surplus electricity will be supplied to the electricity grid responsible for the place, as well the biofertilizer will be sold. With the development of the project, a production of 175 MW of energetic power a month and 4.589.976,53 kg every 120 days. The economic analysis found a return on investment in the fifth year, demonstrating that the project is economically viable.
