Management of construction and demolition waste.

Waste materials are common problem in modern living. Waste accumulates from number of sources including domestic, industrial, commercial, construction and demolition activity. A significant portion of municipality waste is construction related. Proper management of construction and demolition waste is important or else it will get mixed with municipal waste. This type of mixing leads to cutting off the recycling options for C and D waste and also reduces the efficiency of further municipal waste processing. Land disposal of C and D waste presents a threat of ground water contamination because of trace amount of hazardous constituents, which are some times encountered. In this article possibilities of C and D waste recycling options are discussed, which includes recycling of concrete aggregate; their properties and constrains in reusing of C and D waste concrete. This also highlights the possible use of recycled aggregate in which further research is necessary.
