ABSTRACT:     The aim of this study was to compare the properties of wood and charcoal of Eucalyptus sp., from two silvicultural systems (replanting and coppicing), in addition to assessing the economic viability of both systems, through the financial indicators Net Present Value (NPV), Internal Rate of Return (IRR) and Payback. The study was carried out in a charcoal producing company, located in the municipality of Itamarandiba, Minas Gerais, Brazil. The results showed that the wood from the coppice system has a lower Mean Annual Increment and a higher heartwood/sapwood ratio, producing a more friable charcoal and with lower productivity compared to the replanting system. Regarding the economic analysis, both systems were economically viable, with an IRR greater than the discount rate and a positive NPV. Comparatively, the economic results of the coppice system were slightly better, presenting less vulnerability in the sensitivity analysis regarding fluctuations in the price of charcoal. The option for coppice may be interesting for the producer due to its lower financial expenditure and satisfactory economic results, although with lower product quality.

RESUMO:       O objetivo deste estudo foi comparar as propriedades da madeira e do carvão vegetal de Eucalyptus sp., provenientes de dois sistemas silviculturais (replantio e talhadia), além de avaliar a viabilidade econômica de ambos os sistemas, por meio dos indicadores financeiros Valor Presente Líquido (VPL), Taxa Interna de Retorno (TIR) e Payback. O estudo foi realizado em uma empresa produtora de carvão vegetal, localizada no município de Itamarandiba, Minas Gerais, Brasil. Os resultados demonstraram que as madeiras provenientes do sistema de talhadia apresentaram menor incremento médio anual e maior relação cerne/alburno, produzindo um carvão mais friável e com menor produtividade em comparação ao sistema replantio. Em relação à análise econômica, ambos os sistemas foram viáveis economicamente, com TIR maior que a taxa de desconto e VPL positivo. Comparativamente, os resultados econômicos do sistema de talhadia foram um pouco melhores, apresentando menor vulnerabilidade na análise de sensibilidade quanto a flutuações do preço de carvão. A opção pela talhadia pode ser interessante para o produtor em função de seu menor dispêndio financeiro e dos resultados econômicos satisfatórios, embora com menor qualidade do produto madeireiro.
