Holy cow! Air freshener venture is dung and dusted

Tuesday, 26 March 2013 | By Michelle Hammond

Two Indonesian high school students have made a liquid air freshener from cow manure.


Dwi Nailul Izzah and Rintya Aprianti Miki won the country’s Science Project Olympiad with their environmentally-friendly air freshener that doesn’t contain any harmful chemicals.


The two girls used cow dung from a cattle farm and left it to ferment for three days, then mixed extracted water from the dung with coconut water.


The distilled liquid has a “natural aroma of herbs”.


Environmentally-friendly products are launching across every consumer category, suggesting there’s room in the market for more. Can you think of a product you could create?
