KLM Dutch Airlines is flying partially on used cooking oil between NY and Amsterdam over the next 25 weeks, Reuters reports.
The pilot is a partnership between KLM Royal Dutch Airlines, Delta Air Lines, the Port Authority of New York and New Jersey and Schiphol Group, which operates airports. The purpose of the pilot is to increase demand for aviation biofuels to help bring the price down, the biggest barrier to more widespread adoption.
The first commercial flight ran on these fuels in November 2011. On October 29, 2012, the first civilian jet flew for an hour powered by 100% renewable biofuel. Read the history on sustainablebusiness.com.
