Análise econômica da produção de carvão vegetal na região centro-oeste do Rio Grande do Sul

Abstract

The present study verified the economic viability of the production of charcoal for barbecue in the Midwest region of Rio Grande do Sul, from the forno-fornalha System, in addition to proposing the expansion of the forest base in the region for the supply of wood for production of charcoal through Silvipastoril System of triple lines. The data used for the analysis were the consumption of charcoal from the residential and commercial sectors, made available by the last Energy Balance of Rio Grande do Sul (BERS), number of households in the region at the Brazilian Institute of Geography and Statistics (IBGE) and number of commercial establishments (restaurants and steakhouses), available at the Ministry of Labor and Employment - MTE and areas with pastures made available by the IBGE Agricultural Census. Based on these data, the demand for charcoal in the region was estimated and further analysis of the economic viability of producing coal in a forno-fornalha system in the region under study. The financial criteria used were the Net Present Value (NPV), the Benefit-Cost Ratio (B / C), the Average Production Cost (CMPr) and the Annual Equivalent Value (VAE). The attractiveness rate adopted was 4% per year. The study shows a demand in the region for charcoal of 4,534,591.85 kg / year, which is not fully met by regional producers. The charcoal production for proposed 6- years scenario indicated a positive NPV of R$ 348,521.56, a B/C ratio of R$ 1.22, a CMPr of 1.84 and a VAE of R$ 65,807.24, indicating the viability of the project. The study also shows a potential for expansion of the forest base in the region of 567,232 hectares, which can be converted into Silvipastoril System for the production of wood to be transformed into charcoal. In conclusion, the region has the potential to produce charcoal in a sustainable and economically viable manner.
