Cow dung air freshener

Cow dung air freshener, Two Indonesian high school students have made an air freshener from cow manure. Dwi Nailul Izzah and Rintya Aprianti Miki won first prize in the country's Science Project Olympiad with their alternative and environmentally-friendly air freshener. The air freshener is said to have a natural fragrance of herbs and is good for human health because it doesn't contain any harmful chemicals like other freshener products on the market. The girls collected cow dung from a cattle farm in Lamongan regency of East Java and left it to ferment for three days. Secondly, they extracted water from the cow dung and mixed it with coconut water. Then the liquid was distilled to remove any impurities; the end product is a liquid air freshener with a natural aroma of herbs from digested cow food. The girls will go on to represent Indonesia at the International Environment Project Olympiad race (INEPO) in Istanbul.
