Bio-diesel made from food in oil-rich UAE
The Middle East is a region where car is king and fuel is cheap, often leaving little incentive to find more environmentally-friendly ways of moving around.
But this year, as protests across the Middle East have pushed up the price of oil, the issue of finding alternative sources of fuel has come into sharp focus.
In a region that has one of the highest carbon footprints in the world, one business is taking advantage of the growing pressure to find alternatives to oil. It's set up the Middle East's first scheme to recycle cooking oil into biodiesel. It's proving profitable too, already their client-list contains McDonald's.
