Chinese factory turns cow dung into energy

The dung, urine, and waste water of some 10,000 cows started supplying electricity to China's national power grid last month, the People's Daily reported, as the world's largest cow-dung methane power plant became operational in Inner Mongolia.

With an investment of 45 million yuan (around $US5.7 million) from Mengniu Dairy, China’s largest milk producer, the plant can supply 10 million kilowatt-hours of electricity to the national power grid, the report said.

Cows emit a significant amount of methane, a powerful greenhouse gas, when they belch and flatulate.

Using equipment and technology from Germany, the report said, the facility is able to produce 12,000 cubic metres of methane and generate 30,000 kilowatt-hours of electricity daily.
