Re-refining of Used Lubricating Oil and its Economic and Environmental Implications
66
Used Lubricating Oils if not appropriately treated represent a serious environmental
problem. The direct burning of used oils in conventional combustion devices can create
serious pollution problems.
The re-refined base oils have the same performance characteristics as virgin base oils
made from crude oil.
As far as re-refining technology selection is concerned, a number of criteria need to be
considered before deciding on which recycling technology to adopt.
Re-refining of used lubricating oil is an economically attractive recycling method from
the standpoint of environmental protection and resources conservation.
An efficient used oil collection system is key to successful used oil management
programme.
For many Arab countries, data are not available for the final destination of used
lubricating oil.
10.2 Recommendations
It is advisable to promote public awareness of the improper disposal of used oil and
educate public about the energy and environmental benefits of recycling used oil.
Where legislation does exist, the local authorities should be responsible to enforce the
policies and to implement the regulations set forth.
As demonstrated by Life Cycle Analysis of used lubricating oil, priority must be given
to re-refining of used oil as opposed to its use as fuel oil.
It is recommended to assess the economic viability of any re-refining project taking into
account such parameters as project location, feedstock availability, operating costs and
product pricing.
For a successful re-refining project appropriate measures are necessary, including an
efficient collecting system, state financial support through taxes and levies and
regulations to encourage investment in re-refining.
