Today I was with the co-ordinator of ministry of environment and forests and learnt about their newest project which is about used oils.In Turkey we have the capasity to use 350.ooo tone of oil but people can collect just 15.000 tone of it which is a big problem beause in other countries like Germany( their 80% income is from recyclable systems.) or Sweden(they even dont have any rubbish!).So i thought that i have to write an article about that issue.
WHAT IS USED OIL?
We may use the same oil maximum 2 times.The second time should not be used after a long time because the more it wates the more it is oxidized.More that 2nd time of using the same oil just gives our body demages.
WHAT ARE SOME DEMAGES ON THE ENVIRONMENT?

• Spilled oil tends to accumulate in the environment, causing soil and water pollution. Oil decomposes very slowly. It reduces the oxygen supply to the micro-organisms that break the oil down into non-hazardous compounds.

• Toxic gases and harmful metallic dust particles are produced by the ordinary combustion of used oil. The high concentration of metal ions, lead, zinc, chromium and copper in used oil can be toxic to ecological systems and to human health if they are emitted from the exhaust stack of uncontrolled burners and furnaces.

• Some of the additives used in lubricants can contaminate the environment. E.g. zinc dialkyl dithiophosphates, molybdenum disulphide, and other organo-metallic compounds.

• Certain compounds in used oil - eg poly-aromatic hydrocarbons (PAH) - can be very dangerous to one's health. Some are carcinogenic and mutagenic. The PAH content of engine oil increases with operating time, because the PAH formed during combustion in petrol engines accumulates in the oil.

• Lubricating oil is transformed by the high temperatures and stress of an engine's operation. This results in oxidation, nitration, cracking of polymers and decomposition of organ- metallic compounds

• Other contaminants also accumulate in oil during use - fuel, antifreeze/coolant, water, wear metals, metal oxides and combustion products.

• 1 lt used oil causes 1 million water?s pollution!!!

• -In my country,Turkey there is a fish which become a tradition called anchovy will not be exist within 150 years.

What We Should Do With Them?
We should bring them to the ?Collection points? and give to the companys who have license.
What the Company Use Them For?
Do not forget that,used oil can not be soap, can not be cleaned or used for anything.But they can used as a liquit which is used in some cars and it is much more friendly than petrol of course. So it makes the situation plus plus.
