Key Metal Refining LLC (KMR) buys scrap catalytic converters as the raw material source for its platinum group metal sales generated through its recovery and refining process.

KMR is a partnership between platinum group metals recovery experts Key Engineering Solutions LCC and a wholly owned subsidiary of catalyst smelting giant DOWA Holdings Co., Ltd. DOWA owns 51% of the company.

DOWA, which has annual revenues approaching $4 billion USD is based out of Tokyo, Japan, and was established over 130 year ago. KMR de-cans all of the catalytic converters it purchases at it's plant and corporate headquarters in Hainesport New Jersey. The material is refined and smelted by DOWA in Japan.

Key Engineering Solutions, LLC was established in May 2001 with the main purpose of providing engineering, process design and consulting services for businesses involved in platinum group metal recovery from automotive catalytic converters.

In 2010 Key Engineering Solutions, LLC expanded its business to include purchasing scrap catalytic converters, processing them to separate the platinum bearing ceramic substrate from the metal housing, sending the catalyst to refiners to recover and purify the platinum group metals suitable to be traded on NYMEX and selling the platinum group metals to automotive manufacturers.

The scrap catalytic converter business is very competitive and requires extensive knowledge of the total platinum group metal content of each converter and of the catalyst material sent for refining. Key Metal Refining LLC has the ability to sample and analyze catalyst samples to properly price converter categories and provide accurate tracking of metal sold for future delivery.
