We value our people and our communities, which is why we work to high production and safety standards and control our environmental impact making efficient use of the resources in our quarrying, manufacturing and port activities.
With such a vision, since 1996 we have had an Environmental Department responsible for improving the environmental performance of the organization and for ensuring that our projects and activities are sustainable. Furthermore, in 2003 we created Asociación Unacem (formerly Asociacion Atocongo), with a mission to implement the company’s social responsibility policy.
