3. Composition of C&D Waste. To effectively handle C&D waste, it is crucial to understand its composition . Two types of waste are produced at construction sites: inert and noninert. Inert waste refers to materials that do not decompose or react chemically, such as concrete, bricks, and asphalt, and accounts for nearly 65% of the total.
