raw materials, in this case crude oil, and environmental protection cost must be
incurred as well to avoid the consequences of extra health and clean up services.
These externalities set the case for the so called subsidies that governments tender
to collectors of used oil and re-refining companies in order to save resources and
protect the environment. In fact some analysts and leaders in the industry
104
do
not use the term “subsidy” but “compensation for the disposal of waste oil
collected.” Moreover, used oil is a pollutant and according to the “polluters pay
principle
”
the consumer must be made to pay for abating the risk of his used oil.
All the above works in favour of the re-refining industry if the generated revenues
from consumers and governments are managed properly to promote and serve the
re-refining industry.

shall not be made responsible to forego sustainability
of resources and environmental and health protection. If not, collectors and re-
refiners may cut corners to reduce cost at the expense of quality and controlled
services.
These considerations are also recognized by the International Environmental
Technology Centre of the United Nations Environmental Program (IETC/UNEP)
which was developed to test the Sustainability Assessment of Technologies
(SAT) in the selection of re-refining process
1,4
. In licensing new projects or even
assessing existing ones, governments are advised to consult the SAT especially
that used oil recovery methods may differ from country to country and that there
is no single model of implementation

Examples of Economic Studies:
It is useful to cite here some examples of economic studies or indicators for
projects of re-refining used oils in some countries.
-
A feasibility study for 80 thousand tons a year re-refining plant in
Turkey called for the use of solvent extraction technology. The study
recognized cases where burning used oils is advantageous in terms of
total environmental impact

energy efficiency and conservation of
resources. It is in any case the preferred method in Turkey and the study
wanted a re-refining plant as a complimentary way in the Istanbul
