RESUMO

This study examines the viability of a sustainable project with the production of palm (Elaeis guineensis) to supply oil to food or cosmetic industries and the use of the residual biomass as a biofuel by a power plant. The biofuel side of the project aims the provision of electricity in part of the so called Isolated System, in southern Roraima. The analysis combines a financial approach, with social and environmental concerns. The starting point is the definition of the area size for planting the crop and fitting the assumptions of the industries (palm oil mill and biomass-fired power plant). In the procedures it is considered the palm oil and palm kernel oil sales for the food and cosmetics industries, while the residual biomass (empty fruit bunches, shells and fiber) is used as a fuel in a thermoelectric power plant. The analysis points to an internal rate of return close to 16,7% and a net present value of US$27.6 million, using a discount rate of 15% per year, for an investment of US$ 280 million. In environmental perspective, the quantitative analysis points to the reduction in emissions of greenhouse gases from the displacement of the Diesel powered plants, quite common in the region, by residual biomass powered one. Such displacement results in a reduction of approximately 444 thousand tons of CO2, as well as the recovery of 28,888 hectare of deforested areas. In social perspective, the project allows approximately 2,888 families to remain close to their homeland, working in appropriated activities for the local biome, obtaining US$3,400 per year only with palm plantation.
