3A Composites employs about 4,400 people worldwide and belongs to Schweiter Technologies, a Swiss company listed on the SIX Swiss Exchange (a Swiss listed company) with headquarters in Horgen (Switzerland). The Singen plant was part of Alcan Singen GmbH until the Rio Tinto Alcan Group sold its worldwide composites business to Swiss company Schweiter Technologies Group. In the course of the acquisition, Singen joined forces with Alcan Kapa GmbH, Osnabrück. 3A Composites has been an independent Schweiter Technologies unit since 1st December 2009.


For 3A Composites, effective, continuous environmental protection is a main priority. It is of utmost importance to preserve natural resources in order to ensure a livable tomorrow for future generations. It commits itself to continuous self-improvement programmes for environmental protection, many of which go above and beyond government regulations.

It is also in this area that 3A Composites strives to be a leader in its field. We were one of the first companies to develop its own environmental management system, which is regularly audited by independent auditors. The successful certification according to EN ISO 14001 and EN ISO 50001 speaks for itself.
