” Producing fertile soil within a very short period of time, from sterile materials and compost, allows us to significantly decarbonise the topsoil sector, such is the process that we wanted to put forward, in a circular economy logic, with our project  ” Land and Fertile Soil ” explains Arnaud Bonneville.

With their project ” Land and fertile soil “, the team represented by Lina Bouvet, Constance Laloye, Romain Bazzana, Arnaud Bonneville and Antoine Faure won the Regeneration Prize of our low-carbon variants competition.

The prize was awarded on Thursday the 13th of October during our Engineers & Citizens evening at the Gaîté Lyrique. It rewards the implementation of a Fertile Soil approach in a French metropolitan area as an alternative to depositing “red soil” in an inert waste storage facility and to adding topsoil externally. The results are very positive for fertile soil, with total GHG (greenhouse gas) emissions 44% lower than in the reference scenario.

This competition was an opportunity to study variants that would significantly reduce the carbon impact of a genuine project, within the scope of the setec Group’s activity, by comparing them with the basic design.

More than 250 employees were involved, 36 entries were received in the first phase of the competition, 22 entries were selected for the second phase and 7 projects were finalists.

Thank you to all the participants for their commitment and for their efforts to find alternative low-carbon solutions for our projects.
