Amsterdam, The Netherlands -- After a series of flights between Schiphol and Paris, Dutch airlines KLM operated its first transatlantic flight on used cooking oil to New York on Friday.
The Dutch company began test flights using biofuels in 2009. KLM started with 200 flights between Amsterdam and Paris. Last year, KLM operated its first intercontinental flight on used cooking oil to Rio de Janeiro.
Many Dutch corporations linked their name to the KLM biofuels project by offering to pay a percentage of the flight tickets for their clients. In Holland the oil used is provided by restaurants and food plants and is used.
When flying from New York to Amsterdam the fuel mix included leftover oil from frying Louisiana's Cajun food.
The KLM flights are powered by a combination of 25 percent recycled cooking oil and 75 percent jet fuel. After the first such flight Friday, the concept will be tested on 24 round-trip trans-Atlantic trips every Thursday for the next six months.
KLM executive Camiel Eurlings jokingly told the New York Post that "it smelled like fries" while the plane was being fueled. The pilots say the cooking oil works like regular jet fuel and does not require any special treatment by airline flight and maintenance crews.
The waste oil from frying up crawfish, cracklins and other Cajun specialties is refined at a Louisiana plant, then trucked to JFK.
KLM says the cooking oil reduces polluting carbon emissions up to 80 percent.
