Building and demolition waste, also known as construction and demolition waste (C&D waste), refers to the byproducts of the construction, renovation, demolition, or deconstruction of buildings, infrastructures, and other structures. It encompasses various materials that are generated during these activities and typically consists of wood, concrete, brick, metal, plaster, insulation, plastics, asphalt, and other non-hazardous wastes.
This waste category typically includes both hazardous and non-hazardous wastes. Hazardous materials can include asbestos, lead-based paint, chemical solvents, and other substances that pose a threat to human health and the environment if mishandled or improperly disposed of.
Proper management of building and demolition waste is essential to prevent environmental pollution, conserve natural resources, and promote sustainable practices. Recycling, reusing, and recovering materials from this waste stream are crucial steps in reducing the amount of waste that goes to landfills.
Waste disposal measures for building and demolition waste may depend on local regulations and include activities such as sorting, separation, and classification of materials at the construction site, followed by transportation to appropriate recycling or disposal facilities. These facilities can include recycling centers, transfer stations, landfill sites, or facilities that use waste-to-energy technologies for energy recovery.
Effective management and responsible handling of building and demolition waste play a vital role in promoting a circular economy and minimizing the environmental impact of construction and demolition activities.
