How does bio-diesel power your delivery trucks and how many lorries are powered by used cooking oil?
May 22, 2018
We recycle the used cooking oil from our kitchens into biodiesel, which we use to help fuel our delivery trucks. We do it by collecting used cooking oil from our restaurants. At a processing facility in Liverpool, the oil is left to settle in large tanks. Smaller and lighter particles float to the top, while heavier ones sink to the bottom. The oil is gently heated and spun to remove water and solids. At this point a process called esterification takes place, a chemical reaction that produces biodiesel. Then filtration and distillation take place. At that point, the biodiesel is ready for use in our delivery trucks.
