Chapter 7 - Conclusions and Recommendations
In this report, the question of used lubricating oils has been discussed from all
angles relating to its impact on the environment and the risk to human health.
The problems of used oils are now almost an international issue where
governments must do their best to contend with. Even the United Nations
Environmental Program (UNEP) and the Basel Convention on waste disposal are
active on the program of utilizing used oil and the disposal of it.
As the world moves forward in its economic development, population increase
and urbanization it is more likely that environmental laws and regulations will be
tightened further especially in countries where these are still lax. The questions
of waste in general and used oil in particular will get more and more attention
with the attendant objective of preventing the dumping of used oil on the
environment.
The conclusions and recommendations emanating from this report can be
summarized as follow:
1-
There is no doubt now about the environmental impact of disposing
used oil into the environment even in well-designed landfills. Small
quantities of used oils in water supplies, rivers, lakes and the sea can
make tremendous damage. Carcinogenic pollutants in used oil are a risk
to human health beyond doubt. Therefore it is incumbent on
government to promulgate the necessary laws and regulations to ensure
keeping out used oil from the environment.
2-
The argument for re-refining used oil or burning it in specialized
industries is not going to be settled soon. Countries have their special
circumstances that must be taken into consideration. The most
important thing is to ensure high collection rates of used oils and burn
them for energy recovery until there is sufficient volume to support a
re-refining plant.
3-
Transportation of used oil across international borders must be
controlled to make sure that it is intended for legitimate use. Having this
