What are the options for used transformer oil?

Used transformer oil can be managed through several options: recycling, reconditioning, and disposal. Recycling involves purifying the oil to remove contaminants for reuse. Reconditioning restores the oil’s properties, making it suitable for further use in transformers. If these options are not viable, disposal must comply with environmental regulations, often involving incineration or secure landfill methods to prevent environmental contamination. Each option should be assessed based on the oil’s condition and local regulations.
