Clear pollution with pollutant

Satyam Thakur, India 13-15

I have made a very cheap filter out of old broken clay pots to absorb pollutants. These spent materials could be either converted into bricks and utilized to make various buildings and houses, or could be reused by drying the absorbed pollutants to be dusted off and disposed of in a proper manner causing no harm to the environment. These biodegradable filters could be used with chimneys and other pollution sources of various industries and vehicles, and later utilized as bricks.
