EPA defines waste oil as any oil that has been refined from crude oil or synthetic oil that has been used and is contaminated by physical or chemical contaminants as a result of such use. Simply put, waste oil is exactly what the name suggests: any synthetic or petroleum-based oil that has ever been used.
With normal use, contaminants such as dirt, metal debris, water or chemicals can mix with the oil and over time the oil will not perform well. At some point, this used oil will need to be replaced with fresh or re-refined oil to get the job done.The EPA Waste Oil Management Standards include a three-pronged approach to determining whether a substance meets the definition of waste oil.
Once oil has been used, it can be collected, Recycled And used Again And again. It is Estimated That 380 million gallons of used oil are recycled each year. Recycled used oil can sometimes be Reused For the same job or Perform A different Job entirely. For example, used motor oil can be re-refined and sold In stores As motor Oil, Or processed Into blast Furnace Fuel.Aluminum rolling oils Can Also be filtered And reused On Site.
be processed on site: the used oil is cleaned of impurities and reused. While this form of recycling may not return the oil to its original condition, it does extend its life.
Use in an oil refinery: The waste oil is used as a raw material in the refinery's production processes.
Rerefining, in which used oil is treated to remove impurities so that it can be used as a feedstock for new lubricating oil.Re-refining extends the life of the oil resource indefinitely. This form of recycling is the preferred option as it closes the recycling loop by reusing the oil to make the same product as when you started, and therefore uses less energy and less virgin oil.
Processed and incinerated for energy recovery, removing water and particulate matter so the waste oil can be burned as fuel to generate heat or power industrial operations. This form of recycling is not as preferable to methods of reusing the material as the oil can only be reused once. However, valuable energy (almost as much as normal heating oil) is provided.
