Recycling is not a “one size fits all” business. To know what to do with your materials, contact us to discuss how we can work with your specific situation.
We accept both canned and de-canned materials and offer de-canning services by our skilled operators at no additional cost..
We accept more diesel catalysts than anyone else in the market, including DPF/filter materials.
Metal honeycomb/foil materials must be kept separate from other materials, since they require a special mill for processing. We can help with these materials as well.
We process a wide variety of industrial catalysts (ceramic, foil, beads) used in oil refining and petrochemical plants.
How It Works
01
De-canning
The first step in catalytic converter recycling is removing the iron shell to extract the ceramic material (honeycomb) inside. This is where the precious metals—Platinum, Palladium, and Rhodium—are found. We’re happy to provide de-canning services for those who prefer not to do this step themselves.
02
Sampling
The second and most important step is sampling. The material must be milled and thoroughly mixed to create a homogeneous batch before a sample is taken. The sampling method itself has a significant impact on accuracy, and we have a dedicated professional to ensure the quality of this process.
03
Final ICP
The sample taken from your material will be shipped by air to Japan for the final assay, ensuring you receive full payment more quickly. Our unique ICP method incorporates a highly automated fire assay process to provide more accurate PGM content (ppm).
