Two students the National Autonomous University of Mexico (UNAM), created a car filter for pollutants, which transforms gases emitted into salts, used in the manufacture of cleaning products!
Martín Morales Trejo and Sarah Díaz, tested the device on a prototype gasoline car and the results were very satisfactory.
The filter is installed in the exhaust to take advantage of the substances they emit, mainly pollutants such as carbon dioxide (CO2) and carbon monoxide (CO).
The good news is that with the small device, the two students managed to reduce pollutant emissions by 92%.
How it works
The filter contains a chemical solution and some mechanisms that retain the maximum amount of gases emitted by the vehicle's exhaust.
These gases that have accumulated in the filter are delivered to partners who transform them into reusable salts in the cleaning industry, or in the treatment of floors.
Thereafter, the salts are converted into household cleaning products, or other substances to be distributed to the market.
Martin and Sarah won a place at the International Youth Science Seminar in Stockholm, Sweden, which is a side event to the Nobel prizes.
Due to the pandemic, the event took place online in 2020.
The two students introduced the device and drew the attention of Donna Strickland, the 2018 Nobel Prize in Physics.
Martin was very moved and hopes that this moment is a starting point for them to get sponsors.
The two students want to take the filter to the market, but they don't have the financial resources yet.
