Colorado Cleantech announced the winners of its 10th Annual Mining Cleantech Challenge, held August 27 at the Governor’s Residence in Denver. The event brought together mining leaders, technology innovators, investors, and industry partners to evaluate solutions designed to make mining safer, cleaner, more efficient, and more productive. Second place was awarded to Travertine Technologies for advancing a circular, carbon-negative electrochemical platform that transforms mining and fertilizer waste into valuable products. Its technology can recycle sulfate byproducts into sulfuric acid and other materials while permanently mineralizing carbon dioxide. The 2026 Mining Cleantech Challenge was supported by Sumitomo Corporation, Royal Gold, Fresnillo, Fortescue, Anglo American, and other industry partners whose expertise helped guide the competitive review and evaluation process.
