Construction & demolition waste

Construction and demolition (C&D) waste consists of materials generated during the construction, renovation, and demolition of buildings, roads, and bridges. These materials often include:

​

• Concrete: From demolished structures and unused concrete from construction activities.

• Wood: Includes lumber, plywood, and wood trim.

• Metal: Steel, aluminium, copper, and other metals from structural supports, piping, and wiring.

• Drywall: Gypsum board, a common interior wall material.

• Bricks: From demolished walls and pavements.

• Glass: Windows, doors, and fixtures.

• Plastics: Pipes, insulation, and packaging materials.

• Asphalt: From road and roofing materials.

• Carpet: Flooring materials from renovations and demolitions.

• Miscellaneous debris: Includes smaller materials like nails, screws, adhesives, and other construction residues.

C&D waste can be significant in volume and can be either inert or hazardous. Proper management and recycling of C&D waste are crucial for reducing environmental impacts and promoting sustainability in the construction industry.
