Abstract
This paper discusses the commonly used re-refining technologies that are used to
regenerate used lubricating oils into a marketable product. The current technologies
and regulations relating to used lubricating oil have been reviewed. The study provides
insights into the economic viability of re-refining. Among the economic advantages it
provides, re-refining represents an economic opportunity to convert a dangerous waste
(low value) stream into high value petroleum product
.
The environmental benefits
deriving from the application of recycling used lubricating oils thru re-refining are
reviewed. This recovery method is recognized to mitigate the environmental impacts. It
is a well established fact that reprocessing to base oil lubricants emits less atmospheric
pollutants and consumes less energy than the refining of virgin oil into lubricants or
burning it for energy recovery.
Also, the regulations and legal frameworks applicable for the management of used oil
have been reviewed. It also identifies obsta
cles and misconceptions facing the re-refining industry. These primarily include access
to used oil and consumer acceptance of re-refined lubricants.
Overall, findings suggest that re-refining represents an economic opportunity for
recycling a low value stream into a high value petroleum product and for reducing the
environmental impacts.
Re-refining is the best option for recycling used lubricating oil.
