Reuse and recycling of construction and demolition material

摘要

Construction and demolition (C&D) activities are a major source of bulky waste materials which take up valuable space in landfills. As the majority of landfills, particularly those in urban areas, are either fast approaching capacity, or are just not available, and as recycling has become a standard requirement in solid waste planning, a number of sorting and processing systems for C&D materials have been developed. These systems range from sorting and processing of the lighter material generated by interior C&D activities to crushign and sorting of heavy exterior demolition debris.
