Construction & demolition waste is a growing problem in a rapidly developing India that infringes upon various environmental functions. When dumped indiscriminately, it destroys waterbodies; adds to dust problems in the city, which in turn contributes to air pollution.
We know today that construction and road dust contributes to PM10 concentration by up to 40% in Delhi in certain seasons and up to 85% in Chennai based on respective source apportionment studies conducted by IITs. It is also important to note that dust per se is not a pollutant but because it gets coated with toxins emitted from vehicles and other combustion, it becomes deadly.
