Zero Dechet Sauvage

MerTerre is proud to present its collaborative platform Zero Dechet Sauvage and its Mediterranean branch ReMed Zéro Plastic.
The aim of this platform is to help reduce the amount of litter that ends up in the sea.

A collaborative platform

Public policies always start with concrete, real-world knowledge. Data on waste collected during clean-up operations are precious, enabling us to trace waste back to its origin and draw up recommendations. A genuine platform for awareness-raising, best practices and knowledge-sharing. MerTerre then analyzes and valorizes the data on the waste collected to guide public policy.

That's why MerTerre has designed and created the Zero Dechet Sauvage platform with the support of the Provence-Alpes-Côte d’Azur Region and the French Ministry of Ecological Transition, developed in partnership with the National Museum of Natural History.

The aim of this project is to create a collaborative tool for pooling knowledge and practices around the issue of litter and structuring the network of stakeholders who are implementing concrete solutions in their territories. Today, we need to pool, homogenize and harmonize our practices, in particular to coordinate initiatives and collections by citizens, associations and professionals, who are becoming increasingly numerous across the territory.

About :
In 2019, with the support of the Provence-Alpes-Côte d'Azur Region and the French Ministry of Ecological Transition, MerTerre created the ReMed Zero Plastic platform. Developed in partnership with the National Museum of Natural History, this platform brings together and federates, on the scale of the southern region, any organization or stakeholder wishing to contribute to the reduction of litter arriving in the Mediterranean, and invites them to use homogeneous characterization and awareness-raising tools to optimize their interventions.

In 2021, the national equivalent of the ReMed Zero Plastic platform : Zero Dechet Sauvage is launched thanks to the support of the French Ministry of Ecological Transition. As federating and versatile tools at the service of a large number of players, the platforms are regularly enriched with news and resources relayed on social networks. With its centralized database for France, the association aims to map litter over time and space, in order to draw up reduction plans adapted to each territory.
