Brazil
Brazil opened a commercial biodiesel refinery in March 2005. It is capable of producing 12,000 m³ (3.2 million US gallons) per year of biodiesel fuel. Feedstocks can be a variety of sunflower oil, soybean oil, or castor bean oil. The finished product will be a blend of diesel fuel with 2% biodiesel and, after 2013, 5% biodiesel, both usable in unmodified diesel engines. As of 2005, there were 3 refineries and 7 that are planned to open. These three factories were capable of producing 45.6 million of liters per year.
Petrobras (the Brazilian national petroleum company) launched an innovative system, making biodiesel (called H-Bio) from the petroleum refinery. In Brazil, castor bean is the best option to make biodiesel, because it's easier to plant and costs less than soybean, sunflower or other seeds.
