Re-refining of Used Lubricating Oil and its Economic and Environmental Implications
11
Keeping in mind, the uncertainty of the data collected from various sources, the
situation of used lubricating oil management in the Arab countries can be summarized
as indicated below:
- It can be stated that the use of re-refining, in Arab countries, is not yet the preferred
waste oil handling alternative.
- Only a limited amount of used oil is actually re-refined as most of the collected used
oil is at best burned as fuel and at worst illegally disposed of.
- The collectable amount, on the MENA regional level, has been estimated to be
around 0.92 million metric tons, which is 58% of the total consumption.
- The quantity of used lube oil actually collected is estimated to be around 464000
metric tons; this represents 50% of the amount available for collection.
- The re-refined quantity is estimated to be around 239000 metric tons, which is 26%
of collectable quantity and 51% of the collected quantity.
- About 74% of collected used oil is used as fuel or improperly disposed of.
- On the MENA regional level, Palestine, Saudi Arabia, the UAE have the highest
collection rates, with 100%, 75% and 70% respectively; Saudi Arabia and the UAE
have the highest re-refining rates with 50% and 36% respectively.
