Till today millions have been spent to clean the Ganga. The Ganga Action Plan (GAP) initialized in 1986 has itself contributed almost ₹ 4000 crores to this spending, but without much success. Meanwhile, two techies from IIEST Shibpur, Prantik Sinha and Sandip Nair have stood up to the cause to clean the ‘sacred’ river with their startup Agastya Buoyant.
Their weapon to rejuvenate Ganga – the elementary theory of buoyancy, shown by sage Agastya. Putting to use the Inflatable Technology they have come up with ‘Trash Boom’ and ‘Underwater Lift Bag’.
A 15 feet long balloon made of polymer coated fabric which if immersed in water, can restrict the movement of floating trash. Each balloon can be connected end-to-end to make a longer chain an cover a larger portion of the water surface. Easy to inflate, a 15 ft long balloon can carry up to 280 kg load.
The Trash Boom can also be deployed as a safety equipment.
Underwater Lift Bag
While the Trash Boom is meant for water surface cleaning, the Underwater Lift Bag addresses the purpose of river bed cleaning. Primarily designed for the Indian Army, the young entrepreneurs have now commercialized it. These inflatable bags can be attached to a drowned object and when charged with air they drag the object to resurface. Conventionally it takes 2 cranes and 50 men to drag out a drowned trawler. But only 10 people are enough to do the same job with the help of Underwater Lift Bag.
The technology is being widely used in the developed countries. The techies from IIEST Shibpur have tailored it be implemented in India. Their venture have won accolades in a Business Reality Show ‘Egiye Bangla’.
A government agency, the Kolkata Environment Improvement Trust have also put to use Agastya Buoyant’s Trash Boom for water body cleaning in the city.
