Alcan (AL) - Get Report will build a $180 million aluminum spent pot-lining recycling plant in Quebec's Saguenay-Lac-Saint-Jean region.

The plant will employ 50 people and has a capacity of 80,000 tons to recycle spent pot lining using Alcan's proprietary technology.

Spent pot lining is the residual material generated in the de-lining of pots following the aluminum smelting electrolysis process. The spent pot lining is composed of carbon and various inert elements and is typically pretreated and land-filled under strict precautions. Through this new process, all of the spent pot lining will be recyclable, providing the global aluminum industry a sustainable reusable solution for spent pot lining's byproducts.

"Alcan is proud to have developed a sustainable, innovative and cost-competitive solution for the treatment of spent aluminum pot lining that could become the standard for the entire industry," said Cynthia Carroll, CEO of the Alcan Primary Metal Group. "Alcan will continue to pursue research in collaboration with our partners to completely recycle the byproducts generated by this process. This plant demonstrates Alcan's ongoing commitment to developing solutions that are not only environmentally sustainable and beneficial for the community, but that also create value for our shareholders," she added.

The plant is expected to begin pot-lining treatment operations in the second quarter of 2008. The site could also process spent pot lining for other Quebec aluminum producers.

Shares rose 57 cents to $40.27.
