processing. The ministry of environment is in charge of regulating, monitoring and
enforcing hazardous industrial waste management requirements through the waste oil
handling and management instructions of year 2003.
Kuwait
In Kuwait, the lubricants market amounted to 50000 metric tons in 2011 (Kamshev,
2012). Assuming an average growing rate of 2.5%, the market is expected to reach 55000
metric tons in 2015. Assuming that only 50% are available for collection, then the
collectable amount would be about 28000 metric tons and the amount of used oil
collected is expected to be around 19300 metric tons per year ( assuming 70% collection
rate). The re-refining installed capacity stands at 27000 MTPY. The management of
hazardous wastes is regulated by Law No. 21/1995 as amended by Law No. 16/1996 and
Decision 210/2001. This categorizes wastes including used lubricating oil as hazardous
or non-hazardous according to the Basel Protocol and the Kuwait EPA regulations
(KOC, 2003).
Morocco
In Morocco, the lubricating oil market size stands at 100000 MTPY. The estimated
quantity of used oil that is collected and recycled to cement plants for burning is only
10000 metric tons per annum. The difference, 90000 metric tons, is unaccounted for.
Most of the waste oil collection and disposal is handled by the informal sector
(Morocco, 2014)). Used oil legislation on the collection, transportation and treatment of
certain waste oils was adopted in 2011 as Decree N° 2-09-85 dated 06/09/2011. As part of
an agreement signed between the Department of the Environment, cement producers
and oil companies, PolluClean, a private company, is responsible for collecting waste
oils to be used in cement factories (ActuMaroc, 2012). The collection rate is very low and
stands at about 10% of the collectable quantity. Used lubricating oils are handled in
accordance with Law 28-00 on Waste (2006) which covers waste oils and lubricants,
which are itemized as either hazardous or non-hazardous waste per Annex I, under
Code 13.08 of Decree No. 2-07-253 dated 18 July 2008 on the Moroccan Waste
Catalogue.
Oman
The principal legislation is Sultani Decree Nº 114/2011, the law on conservation of the
environment and prevention of pollution, which replaces the previous environmental
law, Sultani Decree 10/1982. Hazardous and non hazardous wastes legislation is
