When considering waste as an input, some valorization possibilities converge: reduction of costs, environmental preservation and qualification of human resources. When organic wastes are submitte to the anaerobic digestion process in order to stabilize them and control environmental problems, one of the products generated is the biogas. This work aimed to analyze if it is economically viable to use biogas as vehicular fuel to supply the farm fleet. The long-term viability for the project considered a period of 10 years. In the case of investments, it was considered that the main investments were made in year zero (start) as if the resources needed for the productive processes were disbursed at one time. By symmetry, the company’s entire initial capital stock was sold at the end of the last year under consideration. Three scenarios were analyzed. In a scenario where the biogas from two stables is used and there is a greater investment with the biogas transport and storage system, the Net Present Value is positive, but the Internal Rate of Return (IRR) was lower than the minimum attractiveness rate. In the case of installing the refining and supply system next to the biodigester of one stable, all indicators improve and the IRR is above the minimum rate of attractiveness, which indicates to be the best choice for the project’s equity return. |
