Alcoa

Alcoa Corporation (an acronym for Aluminum Company of America) is an American industrial corporation. It is the world's sixth largest producer of aluminum, with corporate headquarters in Pittsburgh, Pennsylvania. Alcoa conducts operations in 10 countries. Alcoa is a major producer of primary aluminum, fabricated aluminum, and alumina combined, through its active and growing participation in all major aspects of the industry: technology, mining, refining, smelting, fabricating, and recycling.

In May 2007, Alcoa Inc. made a US$27 billion hostile takeover bid for Alcan in an attempt to form the world's largest aluminum producer. The bid was withdrawn when Alcan announced a friendly takeover by Rio Tinto in July 2007.

On November 1, 2016, Alcoa Inc. split into two new entities: Alcoa Corporation, which is engaged in the mining and manufacture of raw aluminum, and Arconic, which processes aluminum and other metals.

After having relocated corporate operations to New York City in 2006, Alcoa moved its headquarters back to Pittsburgh effective September 1, 2017.[9] In October 2018, Alcoa announced plans to move from Pittsburgh's North Shore to a more downtown Pittsburgh location.

Established in 1952, the Alcoa Foundation works to protect and preserve the environment by building partnerships and educating tomorrow’s leaders.

Alcoa Foundation supports programs that create sustainable value for the communities where we operate. Our goal is to contribute to programs that protect and preserve the environment while also promoting equitable access to education and skills-building opportunities.

The Political Economy Research Institute ranks Alcoa 15th among corporations emitting airborne pollutants in the United States. The ranking is based on the quantity (13 million pounds in 2005) and toxicity of the emissions. In April 2003, Alcoa Inc. agreed to spend an estimated $330 million to install a new coal-fired power plant with state-of-the-art pollution controls to eliminate the vast majority of sulfur dioxide and nitrogen dioxide emissions from the power plant at Alcoa's aluminum production facility in Rockdale, Texas. The settlement was the ninth case the Bush administration pursued to bring the coal-fired power plant industry into full compliance with the Clean Air Act. Alcoa was unlawfully operating at the Rockdale facility since it overhauled the Rockdale power plant without installing necessary pollution controls and without first obtaining proper permits required by "New Source Review" program of the Clean Air Act. In February 1999, Alcoa cleaned soils and sediment contaminated with polychlorinated biphenyls (PCB) and lead at the York Oil federal Superfund site in Moira, New York, in accordance with the Environmental Protection Agency. The site, a former waste oil recycling storage facility, accepted waste oil from a number of companies, including Alcoa. The facility was improperly managed and operated and, as a result, soils on the York Oil Property and nearby wetlands sediments and groundwater were contaminated. The United States Environmental Protection Agency (EPA) issued a Superfund Unilateral Order on December 31, 1998, requiring Alcoa to excavate, treat and dispose of the contaminated wetlands sediments.
