The increasing use of biofuels has provided studies and research on new methods and
new raw materials, as it is a renewable fuel with various production possibilities. Another
motivation for this growth is the instability in the price of fossil fuels and environmental
discussions about the emission of pollutants. However, some countries have no natural
availability to facilitate the cultivation and production of raw materials to supply a biofuel
industry. The vast territorial extent and favorable climatic conditions, potenciate the Brazilian
industries and facilitate positive returns for the investments made in this area. For this work it
was chosen as raw material to Brazil nut (Bertholletia excelsa), native tree of the Amazon
region, which has its chestnuts recognized worldwide because of its high lipid constitution
with predominant average levels of unsaturated fatty acids. From the unsaturated fatty acids
one can produce esters with unsaturated chain constituting a low viscosity biodiesel and low
flash point, characteristics closer to petroleum diesel. The aim of this work is to produce
biodiesel, from the transesterification of Brazil's chestnut oil and analyze the electrical and
reagent expenditures for the production of 1 liter of biofuel. The biodiesel obtained was
evaluated according to the standards pre by the federal and international agencies that
supervise the production and sale of renewable fuels, having good results in the analysis of
water and sediments, specific mass, flash point and kinematic viscosity. In the analysis of
total glycerin and acid value, the results obtained were above the values specified in of ANP
and ASTM. The calculated cost of production is inconsistent with the industrial reality
because it was made according to the system used in batch and in laboratory conditions, very
different from a system of continuous production.
