Small spills (< few liters) can be consumed by natural
organisms over a period of 28 days [6]. Larger spills
however, can cause oversaturation and greatly
prolong the natural biodegradability of the oil.
A two MVA transformer requires more than 2000
liters of oil to operate properly. A spill of this size,
typically the result of rupture to corroded tanks,
accidental structural damage, or theft due to
copper harvesting, could be devastating to the
surrounding environment. Oil that enters waterways
poses an immediate threat to nature and wildlife
and to water meant for human consumption.
Huge financial costs can ensue for cleanup and
re-establishment of operations. This burden is
often magnified by a risk to corporate reputation.
Obviously, the oil must be removed immediately to
avoid all further negative outcomes [7].
All transformer oils become contaminated during
operation, thus reducing biodegradability.
Major environmental agency regulations do not
differentiate between ester or mineral oil in their
regulations concerning the handling, spillage
treatment, or disposal of these oils in regard to
environmental or human health impact. Either
at the end of life or following carbon saturation,
ester oils are replaced and, like mineral oil, must be
treated as a bio-sensitive material.
