Large amount of damaged notes, with face value of 100 billion yuan ($15.67 billion), are burned to generate electricity at a biomass power plant in Yancheng city, East China's Jiangsu province, Chinanews.com reported.

It's important to destroy damaged notes having poor anti-counterfeit function as the People's Bank of China regards the notes as the country's business cards and thinks the notes should remain in mint condition to avoid fake money.

"The damaged notes unloaded from the trucks will be burned together with straws after being shredded," said Zhu Hongwei, a fuel worker at the plant.

Zhu added: "A truck of 30-ton damaged notes can generate about 30,000 kilowatt hours of electricity, which can provide electricity to a family for 30 months if the family needs 100 kilowatt hours of power each month."

"One-thousand-and-eight-hundred tons of damaged notes will be burned in a year as five truck loads of them are delivered to the plant every month," said Zhu.
