And till now, 2,900 km of National Highways in India have already been made using this waste. (FYI, India does not even have enough plastic waste to convert all 41 lakh km of its roads this way.)
It all started with Dr. Rajagopalan Vasudevan.
He noticed something simple. Plastic and bitumen both come from petroleum. So, he asked, what if the plastic we throw away every day could replace some of the bitumen used in roads?
He spent years testing it and it worked.
1 tonne of plastic waste = 1 km of road. That’s roughly 10 lakh plastic carry bags, off the streets and under your feet.
And these roads aren’t just cheaper either, they’re stronger too. 10% less bitumen per km, 7+ years of life with near zero maintenance, and reported to be twice as strong as conventional roads.
He patented the technology in 2006, then gave it away to the government for free.
For 9 years, barely anyone used it. Then in 2015 the government finally made it mandatory on most highways. I work in packaging and plastic gets blamed for everything, every single day.
But this story proved something worth remembering. Plastic is not the villain. What we do with it is.
Because plastic isn’t a dead end. Sometimes it’s literally the road ahead.
