At MerTerre, we are convinced that achieving the goal of Zero Litter must be based on the coordination of associative forces and the quality of their relationships, a mission that lies at the heart of all our projects.

Taking action with associations

The associations and federations involved in the issue of litter have valuable knowledge and expertise. In line with their strategy, and in keeping with our ethical charter, MerTerre wishes to strengthen their ability to make a difference.



We work in the regions with various co-pilot organizations, training and providing tools, methods and resources to influence public policy and industry, and bring about concrete changes with measurable results.
