The demolition waste is also dumped along the banks of the city lakes. Finally they end up becoming flat lands and end upbecoming prey for land mafia. A century of this practice has already lead to the drying up of innumerable rivers and lakes. With this amount of demolitionwaste created order of demolition for buildings should be progressive. And adoption of 3R principle (Reduce, Recycle and Reuse) should be followed.Thus up-cycling it has become a crucial job to be done along with using materials in renewable forms.
