    When throwing away trash, do you know which bin it should go in? Some of you might not be able to answer this question. But it's very important to know how to deal with your waste. Not knowing how to deal with waste is harder to save energy and protect the environment.

If you don’t deal with your garbage, all of it will go to a landfill(垃圾场) and be buried together. These landfills can take up large areas of ground. The electronic waste you throw away can pollute the soil and groundwater. Other pieces of garbage can be used to make other things if they are properly recycled.

Many cities in China have taken actions in recent years. For example, Shanghai announced in July that it would divide the garbage into four groups: recyclable, hazardous(有害的), wet and dry.

Paper, metal, glass and other things that can be reused are called recyclable waste.

Hazardous waste includes things like medicine, batteries and fluorescent bulbs(荧光灯泡). These things are not recyclable.

“Wet” waste is also known as household waste. “They are things you don't want but that pigs can eat,” Guangzhou Daily explained.

Some waste such as plastic bags, beer bottles and other man-made things will go in the "dry waste” bin.

Many other Chinese cities plan to use this way to deal with their garbage. Let's encourage each other to deal with our waste well by sorting it to protect the environment.
