Harmony Green Refining
Hoover & Strong has been refining precious metals for over 106 years and we pride ourselves on being the WORLD’S GREENEST REFINER!
Our refinery uses processes that produce 75% less chemicals and create zero waste water discharge. Scrubber systems remove harmful particulates from all exhaust fumes, so only clean air enters the environment. All cooling water for the smelting furnaces is recycled. Hoover & Strong utilizes environmentally-friendly refining techniques that always exceed federal, state and local environmental regulations.
In April 2012, SCS Global Services, a globally-recognized independent third party sustainability expert, certified us as a “Responsible Source” refiner. We continue to receive the renewal certifications for Responsible Source every year.
