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

refiners converting waste oil into base oils and furnace fuels. Hazardous waste
management practices are governed by the Executive Order of Federal Law No. 24 for
Regulation of Handling Hazardous Materials, Hazardous Waste and Medical Waste
(2001). It dictates that waste is to be processed in the most environmentally friendly
way.
It can be noted that used oil handling practices vary from country to country with
Tunisia, Saudi Arabia and the UAE, having probably the most integrated used oil
management system.
According to data gathered from a variety of sources, total market demand for
lubricants in Arab countries stands at about 1.6 million metric tons per year, with
Egypt, Saudi Arabia, the UAE and Algeria amongst the highest consumers. This figure
is expected to grow as a result of the demand from the industrial and transportation
sectors which represent key growth drivers. As shown in Table 1, the used oil recycling
industry is comprised of 21 plants with a processing capacity of ca. 304000 metric tons
per year. Most of the re-refining industry is concentrated in the GCC countries where
the installed capacity reaches 120000 tons per year. A significant amount of new re-
refineries is projected to come into operation in the near future, which should increase
current capacities to 350000 metric tons per year.
Table 1 lists some of the re-refining plants in some Arab countries.
