We may be a speck in the universe, but the universe is nothing without the sum of the specks.
When Dr Rajagopalan Vasudevan, a chemistry professor at Thiagarajar College of Engineering, Madurai, invented a technology to use plastic waste in making roads, he did not know how impactful his lab experiment will become.
Soon after the discovery, the government made it mandatory for all road developers to use waste plastic for road construction. Now that's making a mark as a speck.
