What does Aveiro do?

Founded in 1981 and a Renault subsidiary since 1999, the CACIA (Companhia Aveirense de Componentes para a Industria Automovel) site built both engines and gearboxes before specializing in gearboxes from 2001 (JR and ND models). In 2011, more than 500,000 gearboxes were exported to Renault-Nissan Alliance sites around the world. The site also manufactures aluminum crankcases, aluminum engine components, oil pumps, etc.


The CACIA plant is seeking to optimize its consumption of water and energy, to limit effluent, to increase waste recycling and recovery and to control the chemicals used.

The plant recently renovated its wastewater post-treatment tanks and ventilation system.
