Biofuel ethanol made from corn is less environmentally friendly than gasoline


Familiar practice when mixing corn ethanol biofuel A new study in the US has shown that getting into gasoline may not be as environmentally friendly as using straight gasoline.

Research published in Proceedings of the National Academy of Sciences says that corn-based ethanol is “not a climate-friendly fuel”. In fact, research shows it uses 24% more carbon than gasoline as a result of changes in land use to grow corn for ethanol, in addition to processing and combustion.

This study contrasts with previous research by the US Department of Agriculture. Geoff Cooper, president and chief executive officer of the Renewable Fuels Association in the US, labeled the study “completely fictional and false”, claiming that it cited “assumptions in the field”. worst case” and “data picked from the cherry”, Autoblog reported.

By law since 2005, U.S. refineries are required to mix 15 billion gallons (68 billion liters) of corn-based ethanol into U.S. gasoline each year.

In the UK, Gasoline E10 – contains 10% ethanol – to be replaced by E5 gasoline (5% ethanol) as the standard unleaded form by September 2021. The government claims this will reduce CO2 emissions by 750,000 tonnes per year – equivalent to using Using 350,000 car gasoline on the street.

While in the US the ethanol for gasoline is derived from corn, in the UK it is obtained from materials such as low-grade grains, sugar and waste wood.
