Both a Sulfur Recovery and Prilling Facility
MOST BUSINESSES IN THIS INDUSTRY DON’T DO BOTH – BUT WE DO. AND WE DO BOTH WELL.
We actively participate in reducing area-wide emissions of sulfur dioxide, while also producing value-added sulfur products for agriculture and other industries.
Deep History in the Sulfur Industry
A LEGACY OF TRUST AND CREDIBILITY
We are the longest continually running sulfur recovery plant in North America – and the longest operating producer of bentonite sulfur products for agriculture. And over the years, we made a reputation for ourselves with the “Yellowstone Brand” – a pure, elemental sulfur product that was made into flakes for agronomists to blend and spread.
