The National Program of Production and Use of Biodiesel (PNPB) was launched under the assumption that the drive for castor demand cultivated by family farmers in the Northeast would promote its insertion in the production network of biodiesel and reduce regional disparities. To achieve this priority, the federal government established the mandatory blending of biodiesel with mineral diesel and reserved at least 80% of this market to companies that buy raw materials from family farmers and provide them with technical assistance in the crops. In addition to the market reserve, companies have tax incentives on the sale of biodiesel made from raw materials purchased of these small producers. In the first six years of operation of this program (2008-2013), the results were lower than expected. Using methodology supported in the Tinbergen rule, in the benefit-cost analysis and in approaches of the New Institutional Economics, this Dissertation discusses the reasons for the weak social and regional performance of the PNPB and indicates suggestions for strengthening the integration of the northeastern family farmers on the biodiesel productive chain and reduce regional disparities priorities of this program.
