Alcoa will provide funding for the pilot program, along with $13.5m funding from US Department of Energy through the American Recovery and Reinvestment Act.
The pilot program will use in-duct scrubber technology to capture emissions, and will test a scrubbing process that combines treated flue gas, enzymes and alkaline clay to create a mineral-rich neutralized product.
The firms intend to use a primary byproduct of the aluminum manufacturing process called as alkaline clay or bauxite residue, as well as other alkaline industrial residuals.
Scientists and engineers from Alcoa Technical Center in Pittsburgh, US will lead the three-year project, which has an investigation phase that runs through December.
Following the completion of investigation phase, the project will enter into the pilot testing phase.
