Three students Bijisha, Milan and Anvy from Cardinal Higher Secondary School, Ernakulam, Kerala have designed a working prototype targeting sustainable water from saline water in coastal regions. This is a zero-waste method for the generation of fresh water with very low TDS utilizing renewable energy from waste plastics.

As per the statistics, the water scarcity in India is expected to worsen as the overall population is expected to increase to 1.6 billion by year 2050. There is an urgent need to utilize and leverage the available saline water.

Reverse Osmosis Membranes even with latest technology does not guarantee as a permanent solution to the problem of desalination without rejuvenations. The idea of integrated methodology of zero-waste fresh water generator utilizing energy from pyrolysis of plastics was incorporated. The introduced method is quite economical as compared to the conventional reverse osmosis method.

The team at present have developed only the membrane for the system, but in future they wish to make it a complete product using the membrane.
