Pays a $25,000 prize pool for scalable fixes to sulfate in a steel plant's wastewater.

ClosedUnited States Steel CorporationUnited States

Solvers register on U.S. Steel's Wazoku/InnoCentive platform as an individual or organization Solver, then submit one written proposal in English covering the problem and opportunity, the solution overview, the team's relevant experience, solution risks, and timeline, capability and costs, plus optional online references, with most sections capped at 500 words. Submissions produced solely with genโ€ฆ

Looking for biological, chemical, mechanical or other novel methods to cut sulfate levels in water discharged from U.S. Steel's Keetac iron-ore plant in Minnesota, down to strict permit limits of 14 mg/L monthly average and 24 mg/L daily maximum. Solutions must keep working continuously in cold climates (down to -60F) and hold down capital and operating costs, and Technology Readiness Levels 1 through 6 are all accepted.
