Construction and Demolition Waste Management

Around the world, CDW policies and legislation adopt the 3R or 4R waste minimization system, i.e., reduce, reuse, recycle, and recover [57,58]. This system focuses on four categories: strategies for the management of construction and demolition waste, prevention techniques, and collection, reuse, and recovery practices [59]. The first category includes planning for the management of CDW, taking into account all the areas involved in the construction process. The CDW is identified and quantified in order to decide what treatments are necessary for its separation and recycling. Economic tools that encourage waste management systems and maximize the environmental performance of waste are also taken into account. For prevention and collection, a construction life-cycle study is carried out in the design phase, which demonstrates opportunities for the use of prefabricated and recycled materials and modern construction methods. In addition, success in managing CDW is achieved via adequate logistics and innovation in the practices of handling and storage of the materials. Recovery practices are used in both stationary and mobile plants to maximize the production of high-quality recycled material.
