This is a prototype that I developed at IIT Delhi during summer bootcamp for which I was awarded as Change maker 2025. There is not a single stereomicroscope in my city, so where to see how micro plastics look ? In search of that I found that micro plastics lab at IIT Delhi has it. I applied for summer boot camp and I was the only high schooler selected from my city. 

Problem- Bottled water contains twice as many microplastic particles as tap water (WHO2019) leading to autoimmune diseases, hormonal disablements, cancer and infertility. The average number of microplastics found in bottled drinking water is 94.37gm/ liter / m3.The size of microplastics is from 5mm - 1 micron meter.

 Solution- Me and my team Microplastics developed an ecofriendly and sustainable filter which separates microplastics from water. During this innovation we faced multiple problems like identification and separation of microplastics in water. We did lots of research on current systems of water purifications, where we found the current water purifiers mostly use plastic membranes to filter water which again leads to release of microplastics in water. So we decided to develop a prototype using ecofriendly and sustainable materials. We used muslin cloth and a granular activated charcoal (GAC) and we could filter out microplastics from the water.

Impact - We observed that when bottled water passed through Bio Filter it separated microplastics which were attached to GAC- Granular activated charcoal, and clear water came out.
