Firm Commitment to Sustainable Development

Alcoa is committed to the economic model of sustainable development, and the San Ciprián complex in particular is very conscientious in the conservation of the privileged environment in which it is located. Its continuous efforts have been recognized. Thus, in 1998, the aluminium oxide plant won the European Industrial Environmental Protection Award, the Spanish phase, for the development of the new process of Liquid Solid Calcination, which allows the content of organic material to be controlled in the process and the salt cakes in the aluminium oxide plants to be revalued by means of a new, unique, simple and economic method. This process has made it possible to transform salt cake into a valuable chemical compound as a raw material for the obtainment of aluminium oxide and other chemical products of high added value. In addition to the very important environmental contribution, this technique permits the capacity and efficiency of the factories to be increased.

Another project that is successful for the environment and enriching to production is that which permits alpha aluminium oxide to be obtained from aluminium oxide powder, which was previously just waste.

The environmental efforts of the plant are permanent, and it is alert to new challenges. The company maintains voluntary agreements with the government of Galicia for the common development of projects whose objective is to protect the environment from any industrial impact.
