12.  Focus on the treatment of waste from public works

Most waste from public works is mineral and inert (bricks, concrete, tiles and ceramics, glass, earth, stones, and pebbles). This waste comes mainly from unpolluted sites and constitutes a potential source of raw materials for recovery.

Environmental preservation and increased competitiveness for the companies involved are the two main challenges of reusing materials. Indeed, their use saves exhaustible resources from quarries and limits the associated environmental impacts. It should also be noted that when disposed of in landfills, this waste occupies land that could be put to better use.
