Scientists from the University of Cambridge have developed a system that uses microwaves to convert waste oil into vehicle fuel
It has been estimated that over 8 billion US gallons (30.3 billion liters) of used motor oil are produced every year by the world’s cars and trucks. While some of that is re-refined into new oil or burned in furnaces for heat, neither of those processes are entirely environmentally-innocuous. In other cases, it is simply discarded. Today, however, researchers from the University of Cambridge announced the development of a process that uses microwaves to convert waste oil into vehicle fuel.
