Dutch airline KLM announced Wednesday that it will use a biofuel generated from used cooking oil to power more than 200 commercial flights between Paris and Amsterdam starting in September.
"There will be 50 percent traditional kerosene and 50 percent biofuel extracted from used cooking oil," KLM spokesman Gedi Schrijver told AFP, adding that KLM is the first airline to use this type of fuel in commercial flights.
The company said in a statement that using the fuel involved no technical changes to its aircraft.
"All biofuels used by KLM also have to meet precisely the same technical specifications as traditional kerosene and must not require any adjustments to aircraft engines or infrastructure," the statement said.
Made by US company Dynamic Fuels, the bio-kerosene is produced primarily from vegetable cooking oil that comes from restaurants.
In its statement, KLM noted that "the costs of biofuels need to come down substantially and permanently," before the company could contemplate using "100 percent sustainable energy."
But, KLM said, using the hybrid fuel in 200 flights is "another important step in aviation sustainability."

Iowa State hybrid lab combines technologies to make biorenewable fuels and products
Ames IA (SPX) Jun 21, 2011
Laura Jarboe pointed to a collection of test tubes in her Iowa State University laboratory. Some of the tubes looked like they were holding very weak coffee. That meant microorganisms - in this case, Shewanella bacteria - were growing and biochemically converting sugars into hydrocarbons, said Jarboe, an Iowa State assistant professor of chemical and biological engineering. Some of the sug ... read more
