This news is about coffee. People in London drink a lot of coffee. People have to throw away around 200,000 tonnes of used coffee every year. However, they can still use the coffee grounds(咖啡渣).

One man has a factory. This factory takes out the oils from the coffee. It makes coffee logs(原木). You can use these logs instead of wood. One log comes from the waste of 25 cups of coffee.

The man’s factory makes 50,000 tonnes of logs a year. That is enough to power hundreds of thousands of homes!
