When your pens broken, the battery (电池) in your toy runs out, or you have some leftover food, what do you do with these things? You will probably throw them all into one bin (垃圾箱). But actually, all of these pieces of rubbish need to be sorted (分类) separately (单独地).
Rubbish sorting is a big thing all over the world. In recent years, some Chinese cities have been working hard on it.
Shanghai is asking all of its residents (居民) to sort their rubbish into four groups: wet, recyclable (可回收的), harmful (有害的) and dry.
Wet waste is also known as household waste. “They are things you don’t want but pigs can eat,” Guangzhou Daily joked. Paper, metal, glass and other things that can be reused are recyclable waste. Harmful waste incudes things like medicine, batteries and fluorescent bulbs (荧光灯泡). Finally, any waste that is not wet, recyclable or harmful will go to the “dry waste” bin.
Many other Chinese cities are also using this way to sort their rubbish. For example, Shenzhen has been sorting its rubbish into the same four groups since 2012. Students there also have to learn waste sorting at school.
China is working hard on waste sorting. There is still a long way to go. But it’s never too late to learn how to sort your rubbish rightly and protect the environment.
