Recovery of construction waste

Most of this waste is mineral and inert (bricks, concrete, tiles and ceramics, glass, earth, stones and pebbles from unpolluted sites). The use of this material makes it possible to save exhaustible resources from quarries and to limit the environmental impacts associated with them. Waste can be the subject of other forms of material recovery by replacing materials:

• in quarry backfilling, within the framework of the requirements set out in the quarry operating authorization;
• in development projects (road underlay, sound merlon, etc.).

The environmental impact of these uses of waste must be controlled.

Finally, waste that cannot be recovered must be sent to appropriate storage facilities depending on its dangerousness: inert waste, non-inert non-hazardous waste or hazardous waste.

Commitments for green growth

Commitments for green growth

Four commitments for green growth to date concern the construction sector and, depending on the case, roads. They relate to:

• The recovery and recycling of inert waste from buildings and public works
• Recycling plaster waste
• Recycling flat glass from deconstruction and renovation
• The recovery of wood waste from construction in cement works

The State raises awareness of its operationseurs, encourages the drafting in the notebooks of special technical clauses (CCTP) for buildings and roads, guarantees relating to their deconstruction, as well as the presence of lots dedicated to glass cleaning. It is committed to developing waste diagnosis and promoting sorting of construction site waste at source. It develops guides and ensures, through studies and the organization of events, the promotion and cross-functional animation of activities linked to recycling and the recovery of alternative materials.
