Re-refining of Used Lubricating Oil and its Economic and Environmental Implications
10
While lubricating oil production and consumption can easily be estimated, the quantity
of recycled used lubricating oil is difficult to figure out. In most Arab countries, no or
very little public information is available regarding the collection, treatment and
disposal of the used lubricating oils, notwithstanding the existence of legislation and
regulations. The lack of reliable data means that the problem of used oil management is
not well controlled and/or the laws and regulations are not implemented with
determination and consistency. In our appraisal of the re-refining situation in the Arab
countries, all the figures quoted are based on documented sources, unless otherwise
indicated. Where country data are not available, the quantity of used lubricating oil was
derived or estimated from the market size of virgin lubes based on the following
assumptions: It is assumed that only 50% of virgin lube oils are collectible as used oils,
out of which only 50% are actually collected, and only 50% are re-refined into base oil
(UNEP, 2012).
The findings, displayed in Table 2, show the lube oil consumption per country, and
collection and recycling of used oil in some Arab countries based on limited data made
available in recent years.
