Waste engine oil is not completely unusable, and can be reused through some methods.
First, the waste engine oil can be sent to a professional regeneration agency for treatment. After a series of filtering, cleaning, regeneration and other processes, reused diesel or base oil can be obtained.
Secondly, the new oil filtered from the waste engine oil can be used to make lubricants, such as for the lubrication of mechanical equipment or agricultural machinery. In short, waste engine oil does not have to be discarded immediately.
Through scientific treatment, resources can be reused, achieving the dual effects of environmental protection and conservation.
