Detailed explanation of the submitted project or idea (in English or both English and your language)
The process was designed by a former stonemason, while working on an ancient building. He made the link between "waste" from the cretaceous and our waste. He then imagined a process to accelerate this process : waste' size reduction, binder introduction, and extrusion under a high pressure press. It then creates mineral aggregates that can be reused into construction or road underlays.
Before waste reduction, a waste sorting is realized, then allowing to valorize a maximum of matter.
Since the process does not require heat and mineralize the biogenic materials, it has been estimated that a ton of waste fossilized permits to stock about 300 kg of CO2.

Special Prize Question 1: How does your project or idea make use of local resources, such as materials and knowledge, to tackle its challenge?
Our process allows to transform waste direcltly onto the sorting sites.
It hence removes the need for transportation between sorting site and landfill & incineration sites.
Our binder can also be produced at a local scale an help to mobilize local materials.
Then our aggregates can be reused, allowing a total circular economy !
Special Prize Question 2: How does your project or idea sustain its activities through the involvement of the local community?
Our technology treats the waste directly on the sorting site. It means that it can create direct jobs at a local scale, but it also reduces the impact of traffic or congestion since no trucks are needed to move the waste from the recycling centers to the landfill & incineration centers.
Our aggregates can also be reused locally and helps to build low carbon building next to fossilization sites.
Special Prize Question 3: How does your project or idea eliminate waste or pollution while regenerating natural resources?
Our technology reduces the need for landfill & incineration, the only two ways to treat ultimate waste. Those two process are CO2 / NOX emitters.
By fossilizating the waste, we supress the direct CO2 emissions, but also trap cthe biogenic carbon. One ton of waste treated allows to trap 300 kg of CO2. It also reduces the need for natural aggregates, then helps to preserve the soils
