{"Image ImageDescription": "At this plant outside of Chiang Mai, used cooking oil and palm oil are processed to produce biodiesel. The raw material, cooking oil or palm oil goes into the reactor where methanol and potassium hydrate are added to serve as a catalyst. After an hour of mixing, it is pumped into the rectification tank for washing. After being separated from water, biodiesel remains. An employee with a Biodiesel B-5 (%) T-shirt issued by the Ministry of Energy checks the finished product. King Bhumibol of Thailand has been a proponent of renewable energy for over 20 years. Biofuels can be directly extracted from oil-yielding plants, starch and sugar. Thailand focuses on such raw materials as palm oil, as well as used cooking oil to make biodiesel, and cassava and molasses to make ethanol. (Photo by John van Hasselt/Corbis via Getty Images)"}
