Alcoa Inc. said Thursday it has joined with two other companies to work on technology that captures carbon emissions, neutralizes them and turns them into a commercially viable product.

Alcoa will fund the project along with $13.5 million from the U.S. Department of Energy. It will join with Codexis Inc. and CO2 Solution Inc., to investigate the technology.

The aluminum producer said the companies will use scrubber technology to capture the emissions, then they will collaborate to treat a byproduct of aluminum manufacturing called alkaline clay. The project will try to combine treated flue gas, enzymes and alkaline clay to make a mineral-rich product for use in environmental reclamation projects, the company said.

Researchers at Alcoa's technical center in Pittsburgh will lead the three-year project.

The company secured the government grant to find ways of converting captured carbon dioxide emissions into useful products such as fuel, plastics, cement and fertilizers, it said in a statement.

Alcoa shares fell 10 cents to $18.03 in morning trading Thursday.
