In the present work are outlined some of the production process route for biodiesel production based on Brazilian raw materials with focus on economics improvement through co product valorization from glycerin. The general view of Brazilian biodiesel program and the other perspective process innovations are also reported. Project sythysis with case studies was made for two different routes. In the first route, soya bean oil and castor oil are selected. In the second route we selected simultaneous extraction and transferication process and oil cake as feed stock for biodiesel production with co production of glicerated starch for emulsion from glycerin and fertilizer. The processes that have been used for different process synthesis are: Esterification, Extraction, and Separation process using evaporation and distillation, purification. The preliminary project case study has shown that biodiesel production cost are very high and not have economical viability, but the use of Soya bean, oil cake as feed stock, simultaneous transferication, has been observed to be economically viable for production of biodiesel in Brazil.
