The man who paves India's roads with old plastic

Dr. Rajagopalan Vasudevan, a chemistry professor in India, has a new approach to plastic. "It's time we stop seeing plastic as the enemy and turn it into our biggest resource," Dr. Vasudevan says. By adding molten used plastic into a mixture of bitumen, a substance that binds roads, the professor found a solution that stuck. India has since paved over 16,000 km of roads since 2002 using plastic as part of the process.
