TOKYO (AP) - Scientists in energy-poor Japan said Friday they have found a new source of motor fuel - cattle dung.

Sakae Shibusawa, an agriculture engineering professor at the Tokyo University of Agriculture and Technology, said his team has extracted 1.4 millilitres of a gasoline-like liquid fuel from every 100 grams 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 tonnes of cattle dung are produced each year in Japan, he said.

Liquid fuel from cow dung is unheard of, said Tomiaki Tamura, an official of the Natural Resources and Energy Agency. Japan relies almost totally on imports for its oil and gasoline needs.

The team, helped by staff from the National Institute of Advanced Industrial Science and Technology near Tokyo, produced fuel by adding several unspecified metal catalysts to the dung inside a container and applying a 30-atmosphere pressure and heat of up to 300 degrees Celsius, Shibusawa said. Details of the catalysts could not be disclosed, he added.
The team hopes to improve the technology so that it can be used commercially within five years, Shibusawa said. ....
