Nicolas Cruaud, the founder of Néolithe, is the winner of the 2023 Ivy Tech prize for young French entrepreneurs, which is being awarded this week in Paris. The company was created in 2019 in western France and devised a new eco-friendly process that creates a type of building material thanks to accelerated fossilisation. This allows the company to take non-recyclable waste and turn it into small mineral granules than can then be used in the construction sector.
