3 Sustainability & Wastewater Treatment / November 2014
Veolia’s mission: Resourcing the world
The world is still developing and needs new resources: natural resources, economic resources and human resources. We play our part by designing and deploying solutions for Resourcing the world:
Developing access to resources: Veolia offers operational solutions that consume fewer environmental resources and are more economically efficient, so as to expand both the potential and the accessibility of the resources available.
Preserving resources: Veolia develops solutions to conserve resources and optimize their use, while protecting their quality and efficiency throughout the use cycle.
Replenishing resources: Veolia provides solutions for creating new “secondary” resources that will gradually offset the increasing scarcity of natural “primary” resources, generating new opportunities for social and economic development that protects the environment.
A complete mastery of the water / waste / energy cycle to serve our customers better
