I am civil engineer, expert in Waste Management. I did some works about Construction and Demolition Waste.
Construction and demolition waste (C&D waste) is the waste generated during the building, repair, remodeling or removal of constructions. The constructions can be roads, residential housing and nonresidential building.
C&D waste has traditionally been considered without any environmental problems and has just been landfilled. However, in recent years more focus has been put on C&D waste and data are starting to appear. One reason is that it has been recognized that C&D waste may include many materials that are contaminated either as part of their original design or through their use and therefore should be managed accordingly. Another reason is that it has been documented that a large fraction of C&D waste (about 90 %) can be easily recycled.
I can do complete research for you regarding the issue.
Best regards,
