Resumen
Diante dos diversos problemas climáticos e ambientais enfrentados pela sociedade contemporânea, a busca por fontes sustentáveis de energia, vem ganhando cada vez mais destaque no cenário mundial. Desta forma, o tratamento de resíduos gerados por rebanhos suínos tem se mostrado uma alternativa sustentável na geração de energia elétrica, podendo ser implementado inclusive em locais onde o acesso aos meios convencionais de energia é escasso ou inexistente. O presente trabalho teve como principal objetivo, o desenvolvimento de um projeto, no qual possa ser aplicado em comunidades isoladas ou com dificuldades de acesso à energia elétrica. O estudo iniciase com uma vasta pesquisa bibliográfica a respeito de biodigestores e tecnologias de conversão de energia. Após isso, a partir de um estudo de caso aplicado em uma unidade rural, foi realizada a seleção do grupo gerador, seguido do cálculo de volume da unidade digestora, modelo indiano com 100 m³ de volume útil, obtendo-se ao final, um projeto de possível aplicação em 12 unidades rurais. Embora o investimento inicial requerido no presente estudo seja razoavelmente elevado (aproximadamente R$196222,03), o tempo de retorno do capital investido, de 8 anos e 6 meses, foi inferior quando comparado com unidade de tamanho semelhante e que possui instalado, por exemplo, um sistema de energia solar fotovoltaico.
Face of various climatic and environmental problems confronted by contemporary society, the search for sustainable sources of energy is gaining more and more prominence on the world stage. In this way, the treatment of pig manures has been indicated as a sustainable alternative in the generation of electrical energy, and can be implemented even in places where access to conventional energy sources is scarce or non-exsistent. The main objective of this work was to develop a Project, which can be applied in isolated communities, or with difficulties in accessing electricity. The study begins with a vast literature search regarding biodigesters and energy conversion technologies. Then, based on a case study applied in a rural unit, the selection of the genset was carried out, followed by the calculation of the volume of the digester, an Indian model with 100 m³ of useful volume, resulting in a possible application in 12 rural units. Although the initial investment required in the present study is reasonably high (approximately R$ 196,222.03), the return time on invested capital, of 9 years and 7 months, was lower when compared to a unit of similar size and which has been installed, for example, a photovoltaic solar energy system.
