Projeto e implantação de sistemas de geração de biogás em pequenas propriedades rurais como fonte alternativa de energia

Abstract

Recently biogas was seen only as a by-product of anaerobic decomposition of urban waste, animal waste and sludge source domestic sewage treatment plants. However, rapid economic development in recent years to the constant fuel price rises has encouraged the production of energy from new and economically feasible alternatives sources, seeking to create new energy production means for the economy or the preservation of natural resources, the production of fertilizers and the generation of alternative income source for small producers. This work is directed to small farms. For this we use a rural property located in the city of Piraquara (Paraná) with 12 hectares, and through this project we show how small farmers can improve their source of income and productivity with proper treatment of the household waste and also of animals living the property thus collaborating with the idea of sustainability. Within this context the present study found that the estimation of methane generation in a country estate of 12 hectares is in average of 1,608 m³ of the day with energy power available from 2,302 kWh / day. In this situation justifies the use of the energy supply of biogas and the use of biofertilizers to represent economic and environmental gain.
