Air pollution, like a silent killer, causes the premature death of 4.4 million people worldwide every year. The biggest responsible for this toxic cloud in cities is undoubtedly vehicle exhaust. At this point, a success story rising from Kenya becomes a low-cost and nature-friendly beacon of hope to the whole world.
Two 17-year-old high school students living in Kiambu district, Fredrick Njoroge Kariuki And Miron Onsarigomade a miraculous invention. Young people rolled up their sleeves when they saw people around them falling ill due to air pollution, and even Kariuki’s own childhood friend struggling with chronic lung disease. Conclusion? It means “clean air” and is produced entirely from waste materials. “HewaSafi” system was born!
TECHNOLOGY FROM WASTE WILL CHANGE EVERYTHING
The HewaSafi filter system developed by young inventors is unlike any industrial product we know. This system, created by combining completely local, biological and recycled materials, is completely from 5 different compartments is formed.
The content of the filter is a complete recycling lesson:
-Coconut shells and corn cobs (Agricultural wastes)
-Materials recycled from old batteries
-Steel nets and copper parts
-Live Spirulina Algae: This biological layer, which is the most extraordinary part of the system, cleans gases by absorbing them like a tree.
This environmentally friendly filter is not just a school project that remains on paper. Young people personally tested the system in Nairobi’s famous public transport minibuses. The results of the tests carried out on 5 different vehicles are such that they will disappoint the giant automotive giants:
-PM2.5 (The most dangerous fine particles): It decreased by 93.3%!
-Carbon Monoxide: A 42% decrease was achieved.
-Carbon dioxide: It was reduced by 21.4%.
IT WILL BE FRIENDLY TO BOTH THE WORLD AND THE POCKET
The biggest advantage that distinguishes HewaSafi from its competitors is the production cost. Standard filter systems sold on the market today that function similarly are approximately $390 It has a price tag of around . This waste-based filter developed in Kenya is only for $126 can be appropriated. This means a revolutionary financial convenience for vehicle owners, especially in developing countries.
This innovative move is the prestigious award that rewards environmental projects. Earth Prize It did not go unnoticed by the competition. Fredrick and Miron, who were chosen as the African region winners, now set their sights on the global grand prize. There is no doubt that if they win this global award, they will start receiving offers from automotive giants. It is also said that they are already on the radar of the automotive industry.
The current goal of the young people is to put the filter into mass production with the support and funds they will receive from the competition. High school students, who plan to integrate this system into hundreds of minibuses and vehicles by producing 1,200 units in the first stage, give the following message to the whole world: To save the planet, we don’t need multi-billion dollar laboratories, we need the right vision and some corn cobs!
