A revolutionary discovery

Getting to the root of things to see how they can be improved is how Néolithe’s invention first came about. It grew out of a collaboration between a former stonemason with traditional craftsmanship know-how and two enterprising young engineers.

This knowledge of minerals combined with the application of cutting-edge industrial technologies gave rise to an ethical innovation – fossilisation. They took their inspiration from nature, simulating the transformation of Cretaceous debris into limestone, and the process has revolutionised the treatment of non-recyclable waste materials which, up until now, have been either buried or incinerated.
