Abstract
Biodiesel produced from cottonseed and oil palm is discussed, foregrounded on articles retrieved from databases, coupled to the characterization of the above prime matters within a life cycle approach in the state of Bahia, Brazil. Technical visits in two producing areas were undertaken for better information on biodiesel stages, namely the western and southern regions of the state of Bahia respectively for cottonseed and oil palm. The productive stages of the two cultures are very different: whereas cotton is characterized as agribusiness with intensive fertilizers and pesticides, the oil palm is predominantly grown by familial farms with low technological level. The biodiesel production unit lies more than 800 km from the extraction site, in the case of cottonseed, and approximately 210 km distant in the case of oil palm. Current study delineates the two productive chains and aims at further research to assess their potential environmental impacts.
