Análise da viabilidade econômica do uso do milho como substrato para produção de biogás no Mato Grosso

Abstract

The Brazilian corn production is a world highlight being the second largest exporter of the grain. The Mato Grosso state leads the internal production with 29,5 million metric tons per year of which 70% is exported. As corn is an energy crop largely used in biogas plants in Europe, a financial analysis was conducted to test the feasibility of using corn for the biogas and electric energy production in the Mato Grosso state. Considering the conditions of 2018 crop, the result is positive, with a NPV of R$ 1,2 million and IRR of 12%. Moreover, the energy production would provide an additional tool to the producer commercialization strategy to arbitrate between corn sale and energy production. Additional results show the high return sensitivity to system efficiency, where a 2% increase would deliver additional R$ 2,8 million to the project NPV. In this way it proves that is worth to the producer to seek more efficient plants with the financial limit of this increment.
