This paper presents a model conceived for cenario prospection and project evaluation of small scale castor bean farming, oil extraction and biodiesel production (transesterification) integrated chain. To evaluate the performance of each project the model adopts financial, social and environmental index such as NPV, IRR, SPB, DPB, production costs, family income, number of settled families and employment. The model was implemented in a computational environment, allowing its use as a decision support tool for investments on the castor bean production chain; it calculates the cash flow of the entire project and of each family, including earnings, debts, taxes, interest and amortization.
