Alcoa Inc. (AA - Analyst Report) announced that it has entered into an agreement with Germany-based Bauer Resources GmbH to commercialize its Natural Engineered Wastewater Treatment technology.

The system was developed at the Alcoa Technology Center to mimic the physical, chemical and biological processes of natural wetlands. It uses 40% less energy and with operating costs that are 60% lower than the conventional systems.

It also cleans and disinfects the wastewater without the use of chemicals or any water discharge and odors associated with traditional tank systems. The resultant treated water is of high quality and can be reused in manufacturing processes or for irrigation.

Per the agreement, Bauer will utilize Alcoa’s engineered wetlands technology to deploy wastewater treatment systems across the globe. Bauer Group possesses considerable wetlands technology expertise.

Alcoa has been engaged in engineered wetlands technology development and executes the process at the Alcoa Technology Center, which treats up to 50,000 gallons of wastewater each day. At its Ma'aden facility in Saudi Arabia, the system will reduce water demand by 2 million gallons each day and save more than $7 million annually.

While the current systems require a fairly large portion of land, Alcoa is working to reduce the footprint to the size of a conventional tank-based system.

Alcoa is a global leader in production and management of primary aluminum, fabricated aluminum, and alumina. The company is also the world’s largest miner of bauxite and refiner of alumina.

Alcoa currently carries a Zacks Rank #3 (Hold).
 
Other mining stocks with favorable Zacks Rank are First Quantum Minerals Ltd. (FQVLF), Freeport-McMoRan Copper & Gold Inc. (FCX - Analyst Report) and Denison Mines Corp. (DNN - Snapshot Report). All hold a Zacks Rank #2 (Buy).
