FINANCIAL VIABILITY OF SOLID BIOFUEL GENERATION: A CASE STUDY IN A PELLET FACTORY IN WESTERN PARANA

The growing demand for renewable and sustainable energy sources is driving the search for economically viable alternatives, such as wood pellet production. This article presents an economic analysis of a factory located in western Paraná, aiming to assess the financial viability of pellet production from wood residues, especially pine shavings and sawdust. To this end, fixed and variable costs were identified and quantified, the unit production cost per ton was calculated, the market selling price was analyzed, and a discounted cash flow forecast was prepared over 25 years. The data were obtained through a technical visit, an interview with the owner, and a survey of the assets and inputs used in the production process. The results indicated that the average production cost was R$759.48 per ton, with raw materials being the main component of the variable cost (46%). The economic analysis demonstrated a Net Present Value (NPV) of R$6,582,427.07, an Internal Rate of Return (IRR) of 22.36%, a discounted payback period of 8 years and 1 month, and a Benefit-Cost Ratio (BCI) of 1.12. It is concluded that wood pellet production is economically viable, especially after the stabilization of industrial operations. The study highlights the activity\'s potential as a strategy for valorizing forestry residues and diversifying the energy matrix, reinforcing the importance of logistical and energy efficiency improvements to maximize long-term results.
