China's largest dump is already full - 25 years ahead of schedule.

The Jiangcungou landfill in Shaanxi Province, which is the size of around 100 football fields, was designed to take 2,500 tonnes of rubbish per day.

But instead it received 10,000 tonnes of waste per day - the most of any landfill site in China.

China is one of the world's biggest polluters, and has been struggling for years with the rubbish its 1.4 billion citizens generate.
