Sakae Shibusawa, an agriculture engineering professor at the Tokyo University of Agriculture and Technology, said his team has successfully extracted 1.4 milliliters (0.042 ounces) of gasoline from every 100 grams (3.5 ounces) of cow dung by applying high pressure and heat.
"The new technology will be a boon for livestock breeders" to reduce the burden of disposing of large amounts of waste, Shibusawa said.
About 500,000 metric tons (551,155 U.S. tons) of cattle dung are produced each year in Japan, he said.
In a separate experiment revealing another unusual business potential for cow dung, another group of researchers has successfully extracted an aromatic ingredient of vanilla from cattle dung, said Miki Tsuruta, a Sekisui Chemical Co. spokeswoman.
The extracted ingredient, vanillin, can be used as fragrance in shampoo and candles, she said.
