Tata Chemicals won the award for the Tata Swach nanotech water purifier. Tata Swach has a low-cost, portable bulb which purifies untreated water with paddy husks and nano-silver particles. The bulb indicates when its purifying capacity has been exhausted, a safety measure designed to keep unsafe water from being accidentally consumed.

Ashvini Hiren, COO, consumer products business, Tata Chemicals, said: “It is a great honour to be a recipient of this top innovation award. This serves as pleasant encouragement to our efforts and we hope that with this Tata Swach continues to scale greater heights.”
