The re-refiner's job is to remove all the aforementioned contaminants and restore the oil to itsoriginal condition. The important point to note is that the technology used by Dominion Oil is virtually identical to that used to refine crude petroleum, the difference being that the level of contamination in used oil is much lower that in crude oil. Oil re-refining reduces greenhouse gases and heavy metal emissions when compared to burning used oil as fuel. Re-refining is a better way to manage used oil. It is easier on the environment and transforms oil into a renewable resource.
