Municipal solid waste

The world's cities currently generate around 1.3 billion tonnes of municipal solid waste a year, or 1.2 kg per city-dweller per day, nearly half of which comes from OECD countries. That is predicted to rise to 2.2 billion tonnes by 2025, or 1.4kg per person. The Bank estimates China's urbanites will throw away 1.4 billion tonnes in 2025, up from 520 m tonnes today. By contrast, America's urban rubbish pile will increase from 620m tonnes to 700 m tonnes.
