In the original analysis, the product prices used to calculate revenue per ton are
kept constant and the same is done here in the reduced model. Using today’s
prices of products makes the situation even worse.
The only criticism of this analysis that may come to mind is that the report is old
and probably needs updating. However, this report is often cited in new studies
which means at least in direction and conclusions the findings are still valid.
Fees and Subsidies:
Conservation of resources and environmental protection with respect of re-
refining used oil has been discussed at length earlier. Suffice it to say here that
used oil is a resource that should not be wasted by dumping in landfills where its
impact on the environment and human health is quite risky. At the same time
energy requirement in re-refining is much less than that needed for virgin base oil
production and here also there is environmental and human health gain.
However, resource conservation and environmental and health protection are
externalities as far as the consumer is concerned who cares only about the quality
and cost of the lubricant he uses for his applications.
In economics, according to Wikipedia, an externality “is the cost or benefit that
