๐ŸŒฑ 23 hectares will be returned to nature via the removal of toll barriers.
sanef groupe intends to renaturalize these motorway areas, drawing on the expertise of setec international.

๐Ÿ‘ทโ€โ™€๏ธ setec international is prime contractor for this vast dismantling and renaturation operation
It is joining forces with other setec group companies (setec รฉnergie environnement, setec lerm, setec als) to apply an innovative solution for a circular economy approach : ๐—ง๐—ฒ๐—ฟ๐—ฟ๐—ฒ๐˜€ ๐—ฒ๐˜ ๐—ฆ๐—ผ๐—น๐˜€ ๐—™๐—ฒ๐—ฟ๐˜๐—ถ๐—น๐—ฒ๐˜€. This technique limits the need to export materials from the site (treated gravel; untreated gravel) and recycles them on site by incorporating compost.
It aims to :
๐Ÿ‘‰ Recycling site materials (excluding bituminous layers)
๐Ÿ‘‰ Reconstructing dynamic and functional soils

๐Ÿ”Ž One year’s monitoring of the reconstructed soils is planned to check their state of functionality and evolution during the experimental campaign on two major sites launched at the end of 2023 over a minimum period of one year.
If the results prove conclusive, the technique will be deployed from 2025 onwards, at sites involved in the project to make the Paris-Normandy axis free-flowing.
