Question

When throwing away rubbish, do you know which dustbin it should go in? Have you ever noticed the differently-colored dustbins on the street?

Some of you might not be able to answer this question. However, it's actually quite important to know how to sort（分类）your waste. Not knowing how to sort waste can make it harder to save energy and protect the environment.

If you don't sort your rubbish, all of it will go to a landfill（垃圾清理场）and be buried together. These landfills can take up large areas of ground that could have been used for planting trees or crops. The electronic waste you throw away, such as batteries, can pollute the soil and groundwater. Other pieces of rubbish, like the metal part of a pen, can be used to make other things if they are properly recycled.

With this in mind, many cities in China have been running waste-sorting campaigns（活动）in recent years. for example, Shanghai announced in 2018 that within three years（2018—2020）, all the people living in Shanghai should sort their rubbish into four groups: wet, recyclable, harmful and dry.

Wet waste is also known as household waste. They are things you don't want but that pigs can eat. Paper, metal, glass and other things that can be reused are recyclable waste.

Many other Chinese cities, including Shenzhen, are using this method to sort their rubbish. Now that you know this, perhaps you can do your part to protect the environment and encourage others to sort their rubbish.
