Two fresh graduates of Birla Institute of Technology and Science (BITS),Pilani — Shailee Jain and Palvi Raikar — promises to solve the problem of air pollution at the traffic signals with their device,MossThatch. The device,which was showcased at the Car Cycle and Bike Expo,is a bio-based contraption that can absorb harmful air pollutants such as heavy metals and remove oxides of sulphur and nitrogen.

The device comes with absorption as well as adsorption features that facilitate physical and biochemical absorption. “The device will absorb the harmful vehicular Particulate Matter (PM) and will reduce air pollution that affect cardiovascular and respiratory system. It is a simple,low maintenance and affordable car accessory that can be easily assembled on a car top,giving the car a green look,” said Shailee,23.

It all started when the duo wanted to explore biological solutions to urban vehicular pollution. “One sq m of moss can absorb 10g of particulate matter in a year,which is the average quantity produced by a car in a year. MossThatch would help breathing easy on roads,” said Palvi,23. While Shailee is teaching in a city-based school,Palvi is now working for a private firm in Bengaluru.

The engineers do not intend to commercialise the device now but wants to spread awareness about it. “Once we get inputs from the users,we might add more features to it. The launch of MossThatch in the market will take another six months,” Palvi said. The device is made using mosses. “As students,we did not have enough funds to experiment. Besides,finding a right person who could guide us through research was a difficult task,” Palvi shares.
