2016-41 Dr R Vasudevan: The Plastic Man of India
Rajagopalan Vasudevan is an Indian scientist who has worked mainly in waste management. He developed an innovative method to reuse plastic waste to construct better, more durable and very cost-effective roads. This method will help in making roads much faster and also will save environment form dangerous plastic waste. The roads also show greater resistance to damages caused by heavy rains. His road construction method is now widely used to construct roads in rural India. He obtained his B.Sc, M.Sc and Ph.D degrees from the Madras University and in 1975, joined Thiagarajar College of Engineering, Madurai where he is currently the Dean, ECA. His research mainly deals with waste management specifically use of waste plastics for road construction.
With approx. 9 million metric tons of plastic garbage being shoved into the world's streams and inadequate waste management, it is tough to say whether plastics were actually a boon. This talk presents a low cost disruptive technology to convert plastic waste of any kind into paved roads that are twice as strong, are waterproof, last up to 60 years and have almost zero maintenance cost. This technology will go a long way in curbing the plastic pollution of the world if implemented diligently.
Dr R Vasudevan is fondly called the 'Plastic Man of India'. He has patented a technique to convert common waste plastic litter into a coating for bitumen - the main component in asphalt – used for the construction of roads.
