According to Central Pollution Control Board (CPCB), India generates 15,000 tons of plastic waste everyday, with Delhi alone accounting for 689.5 tonnes a day. In such a dismal situation, a technological innovation such as the one Prof. Vasudevan has devised can prove extremely useful when put in action.
Asphalt and Bitumen are petroleum derived products. As fossil fuels are becoming more scarce, scientists have started looking for alternatives for this and Prof. Vasudevan’s technology might meet this gap. It is a win-win situation for all, it consumes unwanted plastic that is mostly non-recyclable and results in stronger roads by replacing 15% of the more expensive bitumen.
Besides, Vasudevan’s method requires no technical expertise or investment or change in current road-laying procedures. So far, more than 5000 kilometers of roads have been laid with recycled plastic. He holds a patent for his technique but often licenses it for free, traveling around the country to share it with construction engineers.
In a country which is predicted to become the highest generator of waste plastic by 2020, where most of it goes untreated onto dumping sites, Prof. Vasudevan’s technique might provide a definite solution.
