【題目】 Waste sorting is a major issue around the world. Different countries are using different methods to sort their trash.

UK: smart bin

A UK company has invented a "smart bin" to help with garbage sorting. People just need to drop their garbage into the bin. A camera and sensors(感應(yīng)器) in the bin can tell what type of garbage it is and correctly sort it. The bin also compresses(壓縮) the waste so it takes up less space.

South Korea: food aside

South Korea is using a method called "Pay For Your Trash "to encourage its people to reduce food waste. When throwing away trash, people have to separate their food waste from their other waste and put it in a bin. The smart bin then weighs the food. People have to pay for their food waste by scanning (掃描) a bar code(條形碼) on the bin. The more they throw away, the more they pay.

Japan: careful sorting

Japan is leading the world in garbage sorting. They sort garbage so carefully that even plastic bottles and their caps(瓶蓋) go into different bins.

Different types of paper products also have their own bins -newspapers,magazines and cartons (紙板箱). There are also factories that make bags, clothes and dolls out of recycled waste.
