In a gigantic feat and a first from Odisha, Lalita Prasida Sripada Srisai, a 9th grader at the DPS, Damanjodi in Koraput, Odisha won the ‘Community Impact Award’ at the prestigious Google Science Fair 2015 in California, hosted by Google in partnership with the Scientific American that sponsored the Community Impact award, LEGO Education, National Geographic and Virgin Galactic. She has won the award in 13-15 years age group.
Low Cost Bio- Adsorbent
She developed a low-cost bio-absorbent based water purifier which uses waste corn cobs as key ingredient. The project aims to aims to clean waste water by flowing through different layers of Corn cobs which is a cost-effective and simple technique of cleaning water. Corn cobs, she says, are useful for immobilising the contaminants in domestic and industrial effluents, and in ponds, reservoirs and water tanks as well.
Her experiment shows that Corn cobs could clean water up to 70 to 80 per cent because they are suitable adsorbents and have high mechanical strength, rigidity and porosity.

It is a cheap and eco-friendly way of purifying water. And it will also open up a new market for corn cobs that are usually discarded as bio-waste.
$10,000 Prize Money
The winners of the fifth annual Google Science Fair were announced live from Google Headquarters in Mountain View, California. As part of this award, Lalita received $10,000 as prize money. Lalita will be further supported for one year by the organisation to build on her project that makes a practical difference in the community by addressing an environmental, health or resources challenge.
Students and staff of the school at Damanjodi celebrated the news of Lalita’s achievement. Speaking to The Hindu, headmaster of DPS Damanjodi, Trinath Prasad Padhi was all praises for achievement of Lalita, who he claimed was also proficient in other extra-curricular activities like song and dance.
Mr. Padhi said the water purifier developed by Lalita if produced in large scale would be a great help for the poor living in rural areas of south Odisha, who still do not have any access to pure water.
The poor living in rural areas of Odisha still don’t have access to pure water and she believes her water purifier if produced in large scale will be of great help to them
Her interest in science was sparked by her encounter with a tribal farmer who informed her about the low utilization of corn cobs. This began her journey to find out more ways to use waste corn cobs. She plans to pursue a career in agriculture studies.
