PGM Recovery Systems buys loose de-canned auto catalyst nationwide from companies all along the catalytic converter recycling supply chain i.e. automotive recyclers, scrap metal yards, converter buyers and de-canners. Our service provides world class assaying with assays available in 8-9 days after receipt of material. Final settlement and payment is within 2 days of the assay via bank wire.

Edmund Schwenk CEO/metallurgist of PGM Recovery Systems states “The single most important factor in selling auto catalyst is the assay, not terms!  Assay transparency is paramount!  Many de-canners we speak to believe they are not getting correct assays on their material.  Some have de-canned, shipped to other company’s and received less than if they had sold their converters by the piece.

Trust is very difficult to establish with suppliers who have suffered when selling their auto catalyst. We suggest whomever you decide to sell to, first ship a test lot, actually, several smaller test lots. Then slowly stair step up into the relationship as you feel a greater comfort level. If a buyer is pushing you for all of your business constantly, that is not a good sign. 

As many auto catalyst recycling suppliers suggest, ask around the industry what other companies have experienced with auto catalyst buyers. Also, try and find out if there are complaints against that company. 

Allow us to show you how PGM Recovery Systems delivers assay transparency to the marketplace.

We at PGM Recovery Systems do not buy whole converters but we have a program that benefits converter de-canners and can definitely help you if you are not de-canning. The de-canners are the final link in the supply chain before the auto catalyst is shipped to a smelter (auto catalyst recycling), so they extract a profit beyond those who sell their converters whole.

We would like to show you how to de-can using a very inexpensive manner. Our purpose is to first show you how to realize increased value to your bottom line by shipping a trial lot of auto catalyst. You will be surprised at the increased profit. 

Most important is cash flow and we help by providing assays in no more that 8-9 days after receipt. Final payment is within 2 days of the assay. Normal assays from other smelters takes 3-4 weeks and balances 4-6 weeks.

Last, the empty shells are 409 S.S. and the selling of them can defer most of the labor cost to de-can. The 409 stainless steel hulls can have a value of $.05 -$.12 lb. depending on your proximity to a major stainless steel scrap consumer. The low end would be to sell the shells as prepared steel scrap while the high end is for 409 S.S. scrap. The average weight per shell will be approximately 7.5 lbs.

Using the inexpensive method of de-canning, a person can de-can a minimum of 20 cats an hour. Once proficient, that can increase to 30 per hour. 

Example #1
20 shells per hour x 7.5 lbs. x $.07 lb = $10.50 per hour recycled scrap steel value. 
20 shells per hour x 7.5 lbs x $.12 lb = $18.00 per hour recycled 409 S. S. value.

Example #2
30 shells per hour x 7.5 lbs x $.07 lb = $15.75 per hour recycled scrap steel value.
30 shells per hour x 7.5 lbs x $.12 lb = $27.00 per hour recycled 409 S. S. value.

We look forward to showing you the way to greater profits in the catalytic converter recycling business!

Harvesting Sensors

We receive Sensors from large converter brokers and converter de-canners nationwide. To help increase the harvest of Sensors from areas with cold weather conditions, use a little WD-40 on the Sensors when first handling the catalytic converter scrap. Next, cut the wiring harness off close to the Sensor. A ½” air impact wrench fitted with a 7/8” deep impact socket (a standard 7/8” will not hold up) is then used to pull only the sensors that can be removed in seconds. 

Another method in removing rusted are corroded sensors is by using a devise called the Mini-Inductor. It is capable of heating a sensor in seconds, which loosens the sensor so it can be removed with an air impact. The Mini-Inductor is quick and safe, being able to heat a sensor in about 5 seconds without a flame. It will turn the hex nut of  a sensor red hot in 15 seconds. The cost is $599.00

Catalytic Converter De-canners

We have visited several large companies and observed the use of the two methods described below:

1) Prior to de-canning the catalytic converter bin is transported to a work station located near the de-canning station. The operator cuts the wiring harness off close to the sensor and then uses an air impact wrench (described above) to quickly remove the Sensor. The catalytic converter is then placed in another bin located next to the de-canning station for final de-canning.


2) After de-canning, separate the cans with Sensors from the cans without Sensors. While separating use WD-40 on the cans with Sensors. These cans will be stored until they can be harvested for Sensors during a slow business cycle. A much higher percentage of Sensors can be loosened using WD-40 or the Mini-Inductor.

• Volume – Before 2000 catalytic converters had a single Sensor. During 2000 – 2004 they were manufactured with two Sensors. Since 2005 most have four Sensors.

• Availability – Most autos begin to enter the end of life after 11 years, so many of the 2000 – 2003 autos are in the end of life recycling phase. Now more of the 2003 autos will begin hitting dismantlers / scrap processors by 2014. Today, most recycled catalytic converters average two Sensors a unit which is twice the amount available just a few years ago. By 2014 – 2016 we expect to see the average increase to three Sensors per catalytic converter! Another factor is V-6 and V-8 engines have multiple cats and as many as eight sensors, so more sensors will be available to harvest in years ahead.

Pricing – As the volumes of Sensor scrap has increased in the recycling marketplace, pricing models have become more mature and predictable.... benefiting the generator of scrap sensors.
