ABSTRACT
The beginning of this century is marked by the large incentive given to biofuel use in replacement of gasoline. Several countries worldwide, including Brazil, United States, Canada, Japan, India, China, and Europe, are interested in developing their internal biofuel markets and established plans for use of these biofuels. Such interests are mainly motivated by (1) the rising oil prices and recognizing that the global oil reserves are exhausting fast, (2) concern about fuel emissions, (3) the requirements of the Kyoto Protocol and the Bali Action Plan on carbon emissions, and (4) the provision of alternative outlets for agricultural producers (Mussatto et al. 2010).
