Avaliação técnica e econômica de combustíveis utilizados em caldeiras da indústria de embalagens de madeira

Abstract

The need to identify cost-reduction alternatives in the industrial sector is a recurring theme, driven by the constant aim of maintaining business competitiveness. One potential avenue for cost reduction is the implementation of an in-house electricity generation system, given the typically high energy costs faced by the industry. Against this backdrop, this study aims to conduct an economic feasibility analysis for installing an engine-generator system at a wooden packaging plant. Various fuel options were evaluated, including wood chips—a byproduct of the production process. Economic assessments focused on return on investment metrics, specifically Net Present Value (NPV) and both simple and discounted payback periods. Contrary to initial expectations, the calculations and feasibility analyses revealed that the project is not a viable solution, primarily due to the implementation costs of the engine-generator unit.
