Potencial de Produção de Biogás a Partir de Biomassa de Suinocultura com Culturas Energéticas

Abstract

The use of alternative energy sources is driven by the aim of minimizing environmental degradation in order to avoid that natural resources are depleted and slow the advance of global warming caused by emissions of greenhouse gases. Much has been researched about new energy sources, among which may be cited as the main: solar energy, wind energy, hydropower and biomass. The biogas from the biological treatment is distinguished by its increasing use to be a source of clean energy with a great social, financial and environmental return to humanity. To enhance this production of biogas, area researchers see performing various combinations, to evaluate or how best to combine any type of waste and succeed in increasing biogas production, consequently use in the energy sector. Thus, this work presents the objective analysis of the Total Solids removal rate, using the APHA methodology, 2012; Analysis of Higher Calorific Value using calorimeter; Analyze Biogas composition, by a Gas Chromatograph and analysis of biogas production using swine manure, silage medium grain corn, sorghum and pasture ground ruziziensis following a Factorial Planning 23, resulting in higher cumulative production to combination of swine wastewater 90% + Brachiária ruziziensis 10%, with 37.2 liters of biogas in seven weeks. Analyzing - the potential production per kilogram of matter, the highest result was the combination of ARS (80%) + Silage corn (10%) + Brachiária (10%), with 22 L.kg-1. Upon analyzing the result of production per kilogram of total solids, the result of the combination is greater production ARS (90%) + Brachiaria (10%), with approximately 561 L.Kg ST-1.
