Renewable Energy Sources: A Sustainable Strategy for Biodiesel Productions

摘要: Nowadays, the world energetic scenario is moving toward a search for renewable energy matrices, allowing sources to be enlarged produce diesel and/or biodiesel. Biodiesel and clean-burning biofuel that gradually being incorporated into conventional as means of limiting production fossil fuels motivate productivity “ecologic friendly” biofuel. However, some oilseed species used raw materials, even those with lower operational cost vegetable oil, are still great challenge petrochemical industry, given economic competitiveness biodiesel against obtained from fuels. The use alternative may increase costs, which exceed price barrel diesel, leading non-viable production. On other hand, high taxes on petroleum products can reduce difference between them, become economically viable. This situation makes exploration economical non-food feedstocks (e.g., Jatropha curcas) an important research topic. made diverse including soybean, rapeseed/canola, sunflower, safflower, palm, curcas, Raphanus sativus, cottonseed, corn, peanut, coconut, recycled cooking animal fats, also algae. In context energy, biodiversity oilseeds others oily biomass Brazil, USA, Canada, countries in Europe Asia greater potential markets biofuels these sources. incentives using rather than fuel absence sulfur or aromatic compounds, content low crop maintenance, improvement environment, creation new jobs, significant contribution domestic economy.
