Two Indonesia science students have won a gold medal at the country’s Science Project Olympiad with an affordable air freshener made from cow dung
Dwi Nailul Izzah and Rintya Aprianti Miki beat 1,000 other competitors to the prize with their concoction, which was created by collecting unused cow manure from a cattle farm and fermenting it for three days.
They extracted the water from the fermented manure and mixed it with coconut water, after which they distilled the liquid to eliminate all impurities. The whole process took 7 days and made a liquid air freshener with an herbal aroma from digested cow food.
Dwi Nailul Izzah said, “Our air freshener is not supplemented with chemicals to smell fragrant, it’s pure and smells like the natural plants fed to cows. It’s also healthier because it doesn’t contain harmful ingredients such as benzo acetan, like most other air-fresheners on the market”
Izzah and Miki will be competing at the International Environment Project Olympiad in Istanbul
