BIODIGESTORES EM PEQUENAS PROPRIEDADES RURAIS: uma análise da viabilidade econômica para fazendas com consumo de energia de até 500kWh Mensais

Abstract

This study investigates the economic viability of biogas production for rural microproducers whose monthly energy consumption does not exceed 500 kWh. Research becomes crucial given the challenges faced by the Brazilian energy grid, especially in remote and difficult-to-access areas. The purpose of this article is to disclose access to biogas, especially in rural communities where this technology is not yet widespread. Through the explanation of essential concepts for understanding, the financial analysis of the expected return when building a biodigester and the determination of the number of animals necessary to achieve a consumption of up to 500 kWh, it is observed that the three types of biodigesters present significant competitive advantages when compared to the tariffs charged by Cemig. Notably, for this consumption profile, the Canadian model stands out as the most economical option, with a cost of just R$0.12 per kWh.
