Air Freshener Made From Cow Dung

Two Indonesian high school students, Dwi Nailul Izzah and Rintya Aprianti Miki, have impressed the judges at the 2013 Indonesian Science Project Olympiad (ISPO) with their ingenious air freshener made from cow dung. They managed to defeat 1,000 other participants and won the gold medal. Believe it or not, the organic product actually has a pleasant plant-like fragrance.

According to the judges and everyone else who had the chance to sniff the air freshener, it has a surprisingly nice herbal fragrance. Also, the air freshener contains none of the chemicals found in similar commercially-available products, and it’s also more affordable. A conventional 275g air freshener costs US$4, where their 225g air freshener costs just US$2.

To make the manure air freshener, Dwi Nailul Izzah and Rintya Aprianti Miki collected the necessary material from a cattle farm in Lamongam, East Java, and let it ferment for 3 days. Then they extracted the water from the fermented manure and mixed it with coconut water. Finally, they distilled the liquid to eliminate all impurities to get the air freshener. The whole process took 7 days.

The two girls are getting ready to showcase their unique invention at the International Environment Project Olympiad (INEPO), in Istanbul, and are getting ready to file for a patent.
