Used Motor Oil or Waste Lube Oil can really be useless and toxic. A drop of Used lube oil can contaminate thousands and thousands of gallons of water.

It sticks to metals,
It is slow to degrade,
It is the major ingredient of oil contamination of waterways and
It ends up polluting sources of drinking water.
This suggests that it must be properly disposed of because it has more harmful possibilities than usefulness when unrefined, What if it can be re-refined, recycled and made fit for re-use? Awesome yeah? Before I go into the Waste Oil Plant Process, let me differentiate between the three oil types. Not assuming if you do or do not know it all, the three types of oil are VIRGIN OIL, RECYCLED OIL, AND RE-REFINED OIL.

As the name connotes, VIRGIN OIL is simply virgin oil i.e. it is the crude oil that has never been used since it has passed through the refining process. It is the most used, and it sets the standard for oil quality generally.

RECYCLED OIL is used oil that has passed through a filtration system (an Oil Recycling Plant) to remove any and every insoluble impurity. It does go back to being pure again, and this is because the impurities removed does include chemical contaminants. It can be re-used.
