A study of an investment project was developed with the objective of evaluating the economic viability of agro industrial residue application (sugar cane bagasse) in the production of particle board (MDP).The constructed building production unit was initially designed for researches at the Department of Food Engineering of the University of São Paulo -Department of Biossystems Engineering, and this thesis attempted to evaluate the economic-financial viability of the project.Sixteen scenarios were used, where sugar cane bagasse and resin based on ureaformaldehyde and polyurethane based on castor oil were applied in the preparation of the panels in different proportions.The first twelve scenarios were defined based on the variation of the sold products' prices and the variations of the payoff resulting from the use of the different resins and their percentage in the preparation of the panels.For the initial evaluation the investment was financing from own researcher's capital.In the last four scenarios, the effects of the financing source of the project were evaluated through a credit operation with National Bank for Economic and Social Development (BNDES).For these scenarios, the presented economic feasibility was evaluated on the initial stage of evaluation.The method of economic analysis used was Cash Flow and the applied techniques were: Simple Payback, Discounted Payback, Net Present Value (NPV) and Internal Rate of Return (IRR).The project showed economically feasible strictly for the scenarios in which the average and maximum prices projected used urea-formaldehyde resin.The use of financing through a credit operation along with BNDES bank did not improve the established rates, but it was an alternative to make the accomplishment of the project feasible.
