The price of diesel has skyrocketed in Syria in recent years as a result of the country's devastating decade-long war. But in Idlib province, some have turned to a cheap and eco-friendly alternative – Birin, a type of fuel made from the seeds of olives left over from the olive oil-making process.
During the production of olive oil, large amounts of pomace are left behind. These are pressed using a special machine and sundried. They are then ready to be burned for use.
