U.S. Plasma Arc Recycling Export Contract Tetronics

Tetronics International has signed of a deal to provide its plasma arc recycling technology to Oklahoma based Duncan Recycling & Refining to recover precious metals from automotive catalytic converters.

Tetronics International, a Wiltshire, UK based manufacturer of plasma arc recycling equipment for the recovery of precious metals, has signed of a deal to provide its technology to Duncan, Oklahoma based Duncan Recycling & Refining (DR2) to recover precious metals from automotive catalytic converters.

The company said that the deal continues its export success, which it has been establishing across international markets for decades.

Under the contract Tetronics said that it will develop and deliver a plasma refining plant for DR2 to recover the highest amount of precious metals found in catalytic converters, whilst having the smallest impact on the environment.

The plant will have the capacity to process six tonnes of catalytic converters per day - equivalent to around two million catalytic converters every year.

Once recovered, the precious metals will then be sold so they can be reused in a variety of products and processes. According to the technology supplier, waste that isn’t valuable is then converted into an inert material called Plasmarok®, which can be used as a building aggregate.

It was claimed that the system provides the lowest cost per troy ounce (the unit precious metals are measured in) to the producer of any recovered platinum group metals.

Tetronics said that DR2’s president, David Nichols, made the decision to install Tetronics’ plasma arc recycling technology at its plant in Oklahoma after seeing it in action it during a trip to Europe two years ago.

According to the company, after recognising the technology’s potential, Nichols decided to make it central to his new business, which will use plasma to extract and refine the valuable platinum group metals and ceramics found in catalytic converters.
“Duncan Recycling & Refining was established partly due to seeing our technology – demonstrating that Tetronics is a world leader in precious metal recovery,” commented Graeme Rumbol, CEO of Tetronics International.

David Nichols, president of Duncan Recycling and Refining, added: “When it is fully operational the plant will help bring jobs to the area, which will start at around one and a half times the average salary in the area.”

When it is fully operational in 2016, the DR2 plant will be one of 11 Tetronics precious metal recovery plants installed worldwide.

Plasma Arc Recycling of Precious Metals

With one in four of all products manufactured requiring platinum group metals in some regard, it's unsurprising that demand for these costly yet highly useful metals has surged. Primary sources have struggled to keep pace and recycling is on the rise. WMW investigates how plasma arc technology is helping recyclers to bridge the gap between supply and demand.
