Final answer:
E-Hall likely recycles their fryer oil and turns it into biodiesel, a renewable and eco-friendly fuel.
Step-by-step explanation:
E-Hall likely recycles their fryer oil instead of throwing it away. Used fryer oil can be converted into biodiesel, which is a renewable and eco-friendly fuel. Biodiesel is made through a process called transesterification, where the fryer oil is chemically reacted with an alcohol, typically methanol, to create biodiesel and glycerol. This process helps to reduce waste and can be environmentally beneficial. By converting used fryer oil into biodiesel, E-Hall can contribute to sustainable practices and potentially reduce their carbon footprint. Biodiesel can be used as an alternative to diesel fuel in vehicles, machinery, and even for heating purposes.
