Recycling of precious metals used in catalyst parts or catalysts has been a very profitable and very important thing in the world car market for many years, but so far this important issue has been neglected in Iran. Newly recycle these precious metals.
Catalyst is an important component in the car exhaust system that plays an effective role in reducing the pollutants leaving the exhaust pipe. This part has a high price due to the precious metals used in its construction. Unfortunately, some car owners in Iran, after using the catalyst, remove it from the exhaust system. This will emit more polluting gases and harmful to the environment. Catalyst is one of those parts that raw materials and metals used in its construction are completely imported.
Therefore, achieving a way to recycle these raw materials reduces the value of the automotive industry and reduces the need for imports. In this regard, Mega Motor Company has recently announced that it wants to start recycling precious metals in used catalysts.
Davood Afshar, Mega Motor’s vice president of engineering, said that the project to recover materials and metals from used catalysts had been underway since late 1998. He says that in carrying out this project, Tarbiat Modares University University Jihad also collaborated with Mega Motor and as a result, they were able to recycle up to 95% of the catalyst precious metals.
Afshar further reminded that in order to comply with environmental requirements, all engines produced in Iran are equipped with catalysts in the exhaust system. He considers platinum, rhodium and palladium to be the most important precious metals in the catalyst. Unfortunately, none of these metals have been discovered in Iran so far, and all of them enter the country from abroad.
Afshar, regarding the performance of the exhaust catalyst, said that up to 100 thousand and 150 thousand kilometers, the catalyst can not be replaced. But after this operation, due to the formation of different layers on the metals, the efficiency of the catalyst is lost, while the metals themselves are still usable.
Afshar lamented the collection of used catalysts and their sale abroad at cheap prices. But at the same time, he announced the construction of the necessary equipment for the daily recycling of 1 ton of used catalysts in the country.
