Biogas, friendly and sustainable energy for small producers: Cost analysis for a rural farm

Abstract

The study refers to biogas as a form of sustainable energy production for small agricultural producers, having as its central objective the design and budget of a biogas generation system for a rural property, through a practical methodology on the farm With the biomass produced by guinea pig farming and peanut cultivation, applying a cost analysis of implementing a biodigester, it was possible to determine the volume, temperature, pressure and calorific value of the biogas obtained from the biodigestion process, and consequently for the generation of electrical energy for lighting a chicken coop; The unit costs of the biogas generation system were analyzed and the total costs were determined, having an advantage for the small producer in terms of system costs compared to those offered in the market, managing to be in the shortterm bankable range, considering the quality materials of the system.
