Re-refining of Used Lubricating Oil and its Economic and Environmental Implications

Figure 34 Group I base oil market share evolution over the years
Source: own elaboration
On the other hand, it has been observed that in engine oil formulations, the
conventional mineral-based auto lubricants are being displaced by synthetic products
which have better performance characteristics (Moncrieff, 2005). However, it seems that
some of these mixed-composition lubricants would not be suitable for later re-refining
(Fiedler, 2005). This trend will certainly have implications on the re-refining industry
and it can be expected that it will not be favorable to technologies geared towards
producing group I lubricants. These market trends, i.e. the group I being displaced and
the ever increasing part of synthetic lubricants, along with a
number of factors
including technology, crude oil prices, environmental legislation and market
uncertainties,
will shape the future of the re-refining industry.

Conclusions and recommendations
In this section of the report, an attempt is made to draw the appropriate conclusions
and make the useful recommendations that could be used to promote the re-refining
industry in the Arab countries and elsewhere:
10.1 Conclusions
Within the scope of Arab countries legal frameworks for the management of used
lubricating oil vary from country to country. In some countries, legislation is simply
inexistent.
In Arab countries, only a small quantity is re-refined into base oil. Most of the collected
is either burned or improperly disposed of.
