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

used oil generated annually exceeds 200000 metric tons. According to our estimation
the re-refining capacity now stands at 95000 metric tons per year. The waste
management policy is set by the Meteorology and Environmental Protection
Administration (MEPA) through the environment protection standards including the
National Material Recovery and Recycling of Waste Guidance Document. Waste oil
disposal is handled in accordance with the requirements set forth in Hazardous Waste
Disposal Standards 1413-03/1992, Regulations and Procedures for Hazardous Waste
Control (Document No. 01-2002) and Environmental Standards on Material Recovery
and Recycling of Waste 2012.
Tunisia
In Tunisia, about 50000 metric tons of lubricating oils are consumed annually. Using 11
collection centers located across Tunisia, collection has reached 15000 metric tons which
represent 60% of collectable quantity. Only 10000 metric tons are re-refined by
SOTULUB (Société Tunisienne des Lubrifiants) which is also responsible for collecting
and transporting used oil. There exists a re-refining plant with a new revamped
capacity of 20000 ton per year. The Tunisian authorities have set up a public system,
called Eco-Zit, for the collection and the regeneration of the lubricating used oils. It is
financed by contributions from oil companies. Used lubricating oils are governed by
Law 1996-41 of 10/06/1996 on waste control, use and disposal and the waste directive
N°2002-693 dated 01/04/2002. ANGED (Agence Nationale de Gestion des Dechets)
monitors, controls and implements the national strategy ( Anged, n.d)
United Arab Emirates
The UAE is the main lubricants producer in the MENA region with an estimated annual
capacity of 1500000 metric tons, part of which is destined for export (Bambridge, 2015).
Local lubricants consumption is estimated to be around 200000 MTPY (Isaac, 2015).
According to AOG (2014), of the total used oil generated about 75% is collected, 25% are
combusted or discarded inappropriately and the rest is supposedly destined for re-
refining. Furthermore, market estimates reveal that between 100,000 and 150000 metric
tons of waste oils are collected annually (AOG, 2014). By correlating the data, the
amount of collected used oil can be estimated to be around 150000 MTPY, while the
burned quantity would stand at 50000 MTPY. The re-refined quantity would stand at
100000 metric tons per year. Presently, there are about 20 collectors and 8 active re-
