Abstract

The objective of this study was to analyze the economic viability of charcoal production in two conversion technologies: eight surface kilns coupled to a furnace for burning gases (kilns-furnace system) and ten "rabo-quente" or traditional charcoal kilns without burning gases system. An average annual production of 1571 cubic meters of charcoal (mdc) was used to perform the economic analysis. A planning horizon of 12 years and two scenarios were proposed. In the first scenario, after harvesting the wood, the planting of a new forest was performed, and the cost of wood remained constant throughout the planning horizon. In the second scenario, after the harvest, the conduction of shooting was considered, which reduced costs in the second rotation and consequently the cost of wood. The economic analysis was performed by determining the following indicators: Net Present Value (NPV), Equivalent Annual Value (EAV) and Benefit - Cost Reason (B/C). Calculated indicators demonstrated the viability of producing charcoal in the two production systems in both scenarios proposed, but kilns-furnace system presented better values. As conclusion, production of charcoal in the evaluated systems were economically viable. Kilns-furnace system was able to generate more profit to charcoal producer.
