Airlines are trying to reduce their carbon emissions. While Solar Impulse is truly experimental and not allied with the airlines, it does represent a major attempt to make the world cleaner. Now, we learn that United Airlines will be using biofuels, fuel created from farm waste and oils derived from animal fats. It will be making a $30 million investment in one of the largest producers of aviation biofuels, Fulcrum BioEnergy.
Fulcrum turns municipal waste — household trash — into sustainable aviation fuel that can be blended directly with traditional jet fuels. The company claims its technology can cut an airline’s carbon emissions by 80 percent compared with traditional jet fuel.
United is not alone in going down this road. Other airlines are also experimenting with biofuels.
