Polyblend, a fine powder of recycled modified plastic, was developed by a plastic sack manufacturing company in Bangalore, under Ahmed Khan.
This mixture is mixed with the bitumen that is used to lay roads.
In collaboration with R.V.College of Engineering and the Bangalore City Corporation, Ahmed Khan proved that blends of Polyblend and bitumen, when used to lay roads, enhanced the bitumen’s water repellent properties, and helped to increase road life by a factor of three.
The raw material for creating Polyblend is any plastic film waste.
Using Khan’s technique, by the year 2002, more than 40 kms of road in Bangalore has already been laid.
