construction waste is defined as fairly clean, heterogenous building materials which are produced from the various construction activities, as per Tchobanoglous et al., 1993. Construction, renovation and demolition activities lead to the formation of waste.

The construction waste poses great danger to environment. This has put construction industries under pressure to consider suitable methods to protect the environment across all industries including construction.

Quantity and quality of construction waste generated from any specific project would vary depending on the circumstances and types of materials used in the project.

Recycling of construction waste is one way to counter risk to construction wastes. So, the invention of proper technology to recycle these materials is of great importance. For instance, concrete waste can be crushed and used as recycled aggregate.
