Val d’Oise: satellite images to fight illegal dumping

It is an environmental and health scourge that increasingly penalizes communities. Against the proliferation of illegal dumping, mainly located in peri-urban areas, the Val-d’Oise department has adopted a global prevention and control plan for the period 2022-2027.

With more than 200 illegal waste disposal points identified, the territory is particularly affected. “The fight against these deposits generates increasing costs for communities”, deplores Céline Villecourt, vice-president (LR) of the departmental council, delegate for the environment and sustainable development. Each year, the cost of cleaning them amounts to 14 million euros in the territory. Just for the edges of departmental roads, 1.3 million euros are spent each year.

Tracking from space

To better fight against this phenomenon, the department of Val-d’Oise has decided to take the height by relying on the exploitation of satellite images by artificial intelligence. It therefore decided to support the initiative of the mixed union Val-d’Oise Numérique, which launched an experiment at the beginning of the year with the company Disaitek on the community of communes Carnelle Pays-de-France.

Based in Fontenay-en-Parisis (Val-d’Oise), the start-up – which has worked on the detection of exoplanets – proposes to detect the formation of wild deposits from images provided by the Pléiades satellites, deployed by Airbus. For the moment, photos are taken every 15 days on the intercommunality of Carnelle Pays-de-France, and two other intermunicipalities will soon be concerned by the taking of pictures around the forest of Pierrelaye-Bessancourt. The experiment will cover the entire territory by the end of the year.

To encourage the development of this solution on the scale of the whole department, a subsidy of 40,000 euros has been earmarked for the mixed syndicate. “This sum covers approximately half of the costs incurred for the purchase of the photos and their processing”, indicates Rachid Adda, director of the joint syndicate which in particular deployed the optical fiber.

Prevent the accumulation of waste

On the ground, the promises are tempting. “This solution should make it possible to differentiate waste collection centers from wild dumps and to be able to estimate the volumes”, emphasizes Rachid Adda. The objective is to be able to follow the formation of wild dumps, most often far from places of life and roads, before they become too large, and to intervene quickly.

This new system must be coupled with the “AC-Waste” platform – driven by the IDF region – which connects road managers, municipalities, the gendarmerie and the deputy prosecutor for the monitoring and management of reports of deposits wild. These actors will have the data processed by Disaitek and will be able to interact. “Mobile camera loans will be offered on the risk sites identified by the experiment”, specifies Céline Villecourt.

Insufficient professional offer

If the phenomenon of uncontrolled dumps is rooted in uncivil behavior, it is also due to the insufficient supply of public dumps, especially for professionals. In this sense, the department is launching a call for projects for the creation and extension of public waste collection centers open to professionals until February 28, 2023. The aid ceiling will be 400,000 euros per project for civil engineering and construction expenses. equipment.

Awareness-raising actions will be reinforced with the launch of the “Val-d’Oise clean” call for projects intended to provide engineering assistance for associations. A total of 15 projects must be supported in the fall. Finally, the department can also count on the mobilization of the green brigade recently created and made up of former RSA beneficiaries and people in retraining to clean the roadsides.
