Análise da viabilidade econômica da densificação de biomassa residual de serraria

Abstract

The development of energy sources occurred along the history of the human being over the centuries. And, during this time, the energetic matrix of Brazil and the world was based on nonrenewable energy sources. Considering this fact and the need to utilize sustainable energy source options, biomass is a renewable and accessible option in the world. That's why, we aim to, through this work, to study the economic viability of the production of briquette, product originated from forestry residue, that goes through densification process. The study was realized with focus on the region of Ponta Grossa and Castro, cities from Paraná state. To that end were analyzed costs, risks and variables pertinent to production of briquette with raw material originated from sawmills and, from this data, was elaborated the viability analysis, that presents that the calculations of NPV (Net Present Value), IRR (Internal Rate of Return), Index of Profitability and payback. After these calculations, was realized the sensibility analysis, in which variables are altered one at a time and are evaluated which one has more influence over the investment. Finishing the analysis, an optimistic and two pessimistic scenarios were created, with that it was possible to evaluate the behavior of available options in the face of alterations of the variables. Interpreting the data, it's concluded that this type of project requires significant volume to become viable and to compensate its initial investment, the fixed costs and variables influence the project in slightly significative manner when compared to the revenue and initial investment. The availability of raw material (sawdust) is a relevant factor to the viabilization of the production line of briquette, the size of the line must be consistent with the production of residue of the sawmill, because the lack of raw material may result in the need to buy sawdust or halting of production, factor that would directly impact the project.
