About The Catalytic Convertor Recycling Business
Catalytic convertors can be described as pollution-control devices that have chemical coatings along with an arrangement of PGM (platinum group metals). These include palladium (Pd) and rhodium (Rh) and platinum (Pt). PGM”s operates by converting reactions that change one or more pollutants into a harmless gas. Many of the current vehicles that operate on gasoline such as planes, motorcycles, trains, buses and automobiles consist of exhaust systems that feature catalytic convertors.
Due to the fact the catalytic convertors play a very important role in automotive industries and other industries, demands for PGM’s are massive. Over 98% of cars sold new worldwide every year are fitted with this type of device and now account for 51% of the worldwide demands about PGM’s.
The catalytic-convertor recycling is a very big business and is a big role player in the efforts to keep up with the consistent demand of PGM’s which are now scarce.

To try and recover the significant value that is spent on the catalytic convertors, businesses are required to accurately and quickly determine the exact amounts of Rh, Pd and Pt in refineries or the site of collection. The automotive catalyst-materials are made from either metallic substrates that feature an “aluminum oxide” wash coat or ceramic substrate that is typically cordierite coated along with precious metals that contain a wash-coat.
The ratio and the average concentration of the PGM’s along with current market-prices related to these three elements have increased drastically over the past two decades. This is always dependent on the speculation, demand and supply. These specific variations and the tightening of the emission legislation have caused a direct-correlation to occur to the catalyst composition. To date, the composition that is dependent on the fuel type used, the displacement of the engine varies drastically.
The formulations typically consist of some ratios of Pd-Rh, Pt-Rh and Pt-Pd-Rh. Pyro metallurgical processes have been sought after method of recycling PGM-bearing materials like catalytic convertors due to the increased recovery rates. The recycling efforts need to be mixed with a careful elemental-analysis about the metal that has been recovered to derive the chemical composition correctly. This analysis is also used to make sure that the metals are free from hazardous materials and contaminants. The trades that include ground-up materials that are sold as a catalyst are often dangerous due to the contamination of spent nickel-cadmium or lead
