region. There are 15 plats in Turkey based on distillation and clay
treatment but the product is destined for fuel

.
The capital cost of the plant was estimated at $53 million (2012),
operating cost at $23 million a year and revenue at $61 million a year
making the profit before tax at $38 million a year. As good as it is the
project did not attract investors yet.

In the United Kingdom, a study
1
was conducted in 2001 for the
Department of Environment, Food and Rural Affairs (DEFRA) to
compare alternatives for disposal of used oil. They compared two cases
for a 35 thousand tons a year re-refining plant, the first with a clay
treatment costing an average of 9.225 million pounds and the other with
hydrogen treatment costing an average of 16.8 million pounds. For a
targeted 15 to 25% rate of return to encourage investors they found that
the two schemes are money losers or they would need 4 and 5.5 pence
per litre in subsidies to break even.
Even when an existing site was considered the economics improved but
remained sceptical. In a scenario when the rate of return was reduced to
10%, the two schemes improved but remained border line and in any
case 10% rate of return is unlikely to encourage any investor.
Perhaps this is why until today no new re-refining plant is built in the
UK where the country burns its used oil and import additional quantities
for the same purpose.

In 1995 a study in Saudi Arabia was conducted in King Fahad
University and compared tow processes, Meineken and CEP-Mohawk
for 50 thousand tons a year re-refining plant

. The capital cost was
estimated at $28.75 and $17.71 million for the two processes
respectively and the rate of return came to be 11.24 and 45.36%
respectively. However, this study is old and may need major revision.
