in hand helps countries with small used oil collection to find a useful
way of getting rid of it and saving resources.
4-
With the advances made in engines design to improve efficiency and
prolong service life, it is equally important to compliment this with the
use of higher grade of lubricants. Therefore any used oil re-refining
plant must take this point into consideration in selecting re-refining
processes. Solvent extraction and hydro-treating process are becoming
the alternatives of choice as other processes add hydro-treatment step
to stay in the reckoning.
5-
While economics of re-refining and even burning for energy recovery
is very important, it should not be the only deciding factor as to the
solution of used oil disposal. Government should seek to support the
industry through surcharges on lubricants use (pollution pays principle)
or by straight subsidy to the operations of collectors, re-refiners or fuel
processors. As said in the report, this is a charge to dispose of used oil
and protect human health and the environment on the way.
6-
Every effort must be made to make the public aware of the dangers of
disposing used oils into the environment. Heavy fines must be
introduced and at the same time reasonably easy to access collection
centres must be provided for those who change oil by themselves. The
small maintenance shops must be prevented from changing oil unless
they can deliver the used oil to a collection centre properly.
7-
The system of making used oils generators charge the collectors
encourages the generators to collect the oil and manage it properly.
However, it is also seen as a way for the generators to cheat by mixing
other waste oils or even water with the used oil. This can be avoided by
having collectors test the used oil and have the right to refuse collection
of tampered with used oils and report the generator for further action by
the authorities.

The system of imposing surcharges on lubricants manufacturers
according to their sales is much more widely used and seems to be the
better way to use the revenue generated as such to support collectors or
