Thirteen-year-old Lalita Prasida Sripada Srisai from Odisha won the Community Impact Award at the prestigious Google Science Fair competition in California on Tuesday. The young scientist’s project was on development of low-cost bio-absorbent based on corn cobs.
The DPS Damanjodi student in Koraput has created a project which aims to clean waste water by running it through layers of corn cobs, powdered corn cobs, activated charcoal made from corn cobs and fine sand. This is a cost-effective and simple technique which is useful in immobilising contaminants in domestic and industrial effluents, and in ponds, reservoirs and water tanks.
The award with a cash prize of 10,000 US Dollar has been sponsored by Scientific American. Lalita will be further supported for one year by the organisation to build on her project. She has won the award in 13-15 years age group.
