Resumen
The use of Biodiesel allows several advantages over diesel fuels such as lower pollutants emission profiles into the atmosphere, hand jobs posts creating, and reduction of imported diesel fuel. Since the program has begun, the soybean oil has been used as mainly raw material to biodiesel production. In fact, this culture is the only that can afford the production needs from biodiesel facilities. However, this oil is a commodity and alternatives fatty materials sources have to be found in order to increase the competitiveness of the process and release the oilseed production to food industry. This work has focused on evaluating the potential use of castor oil, ouricuri, babassu, castanets, macauba and seeds of passion fruit and pinecone as alternative sources to biodiesel production. The results have shown that the evaluation of moisture content of the samples plays an important role before oil content determination and except the seeds of passion fruit, all of them shown oil potential to supply biodiesel production needs.
