Local authorities


Zero Dechet Sauvage is a real dashboard to fight litter in your area, you will find :

  • information and datavisualisations to understand the state of pollution by litter (hotspots, origins, sectors of economic activity, behaviours) ;
  • tools to monitor the evolution of these pollutions ;
  • tools to act coherently with local stakeholders.

Local authorities are on the front line in the fight against litter problem in their areas. They have a key role to play in solving the problem, with action plans and appropriate tools.

Taking action with local authorities

The local authorities have been endowed not only with powers, but also with a growing responsibility and willingness to act to tackle the waste dumped on their territories.


Due to a lack of time and resources to take action, local authorities have told us that they need support in tackling this issue. They wish to obtain tools adapted to the specificities and problems of their territories to fight diffused litter.


That's why we're working with our network to develop customized support tailored to their needs.

How to act together ?

We can offer you customized support and a toolbox to help you make the right decisions :

Territorial diagnosis

You have targeted a problem related to
littering in your area.
MerTerre offers support in carrying out a complete territorial diagnosis.

This assessment enables us to get a good grasp of the current waste situation, so that we can put in place a response plan tailored to the problem.

A comprehensive knowledge survey will be carried out in consultation and collaboration across the entire area concerned.


of a plan to tackle
Based on the territorial diagnosis, priority lines of action will be chosen to appear in the action plan.

Thanks to a directory of solutions, stakeholders will be able to draw inspiration from concrete actions that have proved effective in areas similar to that of the local authority.

This stage will lead to the co-construction of an action plan adapted to the needs and constraints of the area.

Knowledge acquisition

To manage,
you need to know.
Acquiring new knowledge may be necessary to gain a global vision of litter problems in a given area.

MerTerre offers rigorous, high-performance knowledge-acquisition methodologies adapted to each territory.

These methodologies are easily accessible and applicable in the field, enabling stakeholders to enhance their skills.


To find out how effective an action plan is,
it is essential to set up a
follow-up plan for selected reduction actions.
A monitoring methodology, adapted to the local area, will be developed based on quantitative and qualitative monitoring, with feedback from those working in the field.

It will enable us to evaluate and redirect the action plan, to reach the objective of zero waste abandoned on the territory.
Littering and local authorities, legislation is evolving !

Regulations are evolving in favor of making producers and marketers of consumer products more responsible, through the "Extended Producer Responsibility" (EPR) policy. Based on the "polluter pays" principle, EPR means that manufacturers are progressively required to bear part of the cost of waste management, from production to disposal. These manufacturers can finance eco-organizations, which are government-approved organizations, or set up their own individual systems to meet specific collection, eco-design, recycling and reduction targets for certain waste streams. The eco-organizations, in turn, can finance local authorities to help them achieve the targets set by EPR regulations.


In particular, the AGEC law (Anti Gaspillage et Économie Circulaire) extended the scope of EPR schemes to new waste streams, and strengthened recycling targets for some of these schemes. It extends the principle of responsibility to include the cleaning up of certain types of waste in public spaces, and the achievement of quantified targets for the reduction of certain waste streams abandoned in the environment.


Clearly, the operation and reinforcement of EPR systems means that local authorities are given increased financial resources to achieve these objectives. In addition to changes in EPR regulations, local authorities are increasingly looking for tools and support in their fight against the amount of waste abandoned on their territory.

In this context, eco-organizations and local authorities need to obtain data on waste deposits, origins and transfers on their territory, as well as their evolution over time.


This is where the platforms designed by MerTerre and its expertise in litter come into play.
