The main contributor to carbon dioxide emissions, the burning of fossil fuels (1), can be reduced by using hemp for biodiesel. The production of biodiesel is a simple transesterification process (7), where many types of oils can be used as a substrate. For a complete list of plant oils that can be used for biodiesel, visit this website.

How does the biodiesel compare?
"The present studies reveal that methyl ester of hemp oil could be a good option as alternative fuel without any engine modification" -Ragit, Mohapatra, and Kundu at the Department of Mechanical Engineering at Thapar University, India performed a study comparing engine performance and exhaust emissions of hemp biodiesel and neem biodiesel compared to mineral diesel. Their findings were that hemp oil has better viscosity, good cold flow properties, and better emissions (Fig 11 of paper) than mineral diesel. (6)
Growing hemp could open up an industry of biofuel production, and help us progress to a world of cleaner gas emissions and reduced use of fossil fuels."The present studies reveal that methyl ester of hemp oil could be a good option as alternative fuel without any engine modification" -Ragit, Mohapatra, and Kundu at the Department of Mechanical Engineering at Thapar University, India performed a study comparing engine performance and exhaust emissions of hemp biodiesel and neem biodiesel compared to mineral diesel.

HME100= 100% Hemp methyl ester
HME80= 80% Hemp methyl ester, 20% mineral diesel
HME60= 60% Hemp methyl ester, 40% mineral diesel
and so on..
