TOLLING

The availability of PGMs is one of the biggest challenges of the future and, with pricing uncertain, we’re offering an option where you’ll be able to maintain ownership of your PGMs during the recovery and refining process as well as having product supplied back to you.

Please get in touch with us for our tolling solutions or to discuss bespoke circular possibilities available to your business.

Markets

“PGMs are present in everyday products we use as individuals or as a business. It is no exaggeration to suggest that the world as we know it would not even exist without PGMs.
No matter what industry or process, PGMs are retrievable. Please see below, as an indication, the industries and products where we are able to recover your PGMs from. ”

energy, storage & hydrogen

PEM-Fuel cells & PEM Electrolyser (Hydrogen market)

As the energy-transition is one of the major topics of the 21st century, the use of PEM’s (Proton Exchange Membrane) is widely utilised. In order to ensure the continuity and stability of products going in and out of this sector, we’re able to offer a extensive range of solutions.

Examples of products / industries, not limited to;

  • PGM catalyst powders, inks and/or slurries. Used in the production of, clean of and waste forms from PEM-fuel cells/PEM-Electrolyser

Automotive

Automotive

What we do

As clean air is more and more important, the automotive industry is one of the sources where the air can be cleaned. By using PGMs in the catalysts for examples, toxic gases are largely filtered out of the exhaust fumes. PGMs out of end of life (EOL) car catalysts can be extracted for re-use in new catalysts. Or, the Ir out of the tip of spark plugs are recyclable, we are able to supply you Ir for your production as well. Please get in touch with any questions you might have.
