Is the old, dirty lubricating oil drained from the sumps or cars, trucks and other engines.
Waste oil poses a significant risk to the health of the environment. Just one pint of oil can contaminate a body of water the size of an Olympic swimming pool and make it un-drinkable.
It is illegal to dump engine oil or pour it down the drain, but an estimated 100,000 tons is unaccounted for each year in the UK alone.
How Is Oil Recycled:
Used oil arrives at the processing plant
Sorting takes place on the oils and they are separated out through distillation, to go to separate parts of the plant.
Chemical pre-treatment helps to break down the hydro carbon chains in the oil meaning It becomes less viscous.
The oil is dehydrated (water is drawn off) so that the different minerals can be more easily extracted.
Vacuum distillation is used minerals are separated out according to density and gasoline is recovered as a refinery fuel.
Further distillation separates out the lube oil, which can then be further refined for use as motor or lubricating oil.
- There is a network of over 1000 Oil Recycling Banks in the UK able to receive waste engine oil
- Currently less than a third of all waste oil produced by motorists is recycled. That means that around 13 million litres of waste oil are annually lost into the environment
- Only 4% of world's oil pollution is caused through spills at sea
- If the energy in that oil were to be recovered, it could provide enough energy for the annual needs of 1.5 million people, approximately the population of Kent!
- The volume of waste oil from one oil change is enough to form a film over a 4 acre lake
