Used motor oil can be recycled and repurposed in several beneficial ways instead of being discarded. Specifically, it can be re-refined into lubricant, processed into fuel oil, or used as raw material for the petroleum industry.
Here's a breakdown of its common uses:
-
Re-refined into Lubricant: This is arguably the most environmentally friendly option. The used oil undergoes a refining process to remove impurities and restore its original lubricating properties, essentially creating new motor oil from old.
-
Processed into Fuel Oil: Used oil can be processed and used as a fuel source for heating or industrial purposes. This requires careful processing to remove contaminants that could cause air pollution.
-
Raw Material for the Petroleum Industry: Used oil can be used as a feedstock in the petroleum industry, contributing to the production of various petroleum-based products.
It's important to note that used motor oil is not worn out; it simply becomes dirty. Recycling it through the processes mentioned above conserves resources and reduces environmental pollution. Improper disposal, such as pouring it down drains or onto the ground, can contaminate water sources and harm ecosystems.
