In the United States, Dallas Fort Wert International Airport is one of the first major centers to convert oil from deep fryers at DFW McDonald's restaurants to jet fuel, developing sustainable energy.
To do this, French fries oil and McNuggets are filtered, heated and hydrogen is added to it, reports NBC News.
According to airport officials, such waste cooking oil is very efficiently processed and converted into jet fuel.
"If you're Dallas Fort Worth International Airport and you have a deep fryer in your restaurant, you're refining oil. When you don't have the quality to make this wonderful french fries and we can reshape it, why don't you do it?" Said Chalmer McWilliams to DFW McDonald's franchisee.
Pratik Chandhock, manager of environmental aviation fuel services at Neste US Inc. in Houston, said the chemical composition of oil and jet fuel is close enough.
"If you look at any oil, they all have these building blocks, hydrocarbons. We can take these atoms and then do a magic trick at our refineries and actually mimic the chemistry of jet fuel," he said.
Chandhawk is also convinced that deep-fried fuel is exactly the same as all other petroleum fuels on American aircraft today.
We will remind, passenger's hydrogen plane set a world record altitude.
As EcoPolitica reported earlier, McDonald’s will give new life used paper cups.
