It's not WASTE until it is WASTED!
With the World Environment Day coming, our school is now requiring every student to form a habit of sorting（分类）the waste. Here in our schoolyard we lay four different colours of rubbish bins for different kinds of rubbish. The red is for harmful waste; the blue is for waste that can be recycled; the green is for kitchen waste; the yellow is for other waste.
The followings are some instructions for you.
Glass: Empty bottles without caps can be recycled to make new glass bottles.
Warning: Mirrors and light bulbs（电灯泡）must not be included in the glass waste.
Paper: Newspapers, magazines and boxes must be clean enough to be recycled.
Warning: Paper tissues（餐巾纸）and wall paper are not recyclable as paper and should be kept separately.
PMD waste: Packaging（包装）made of plastic, metal and drink boxes are used to make new packaging.
Warning: Plastic pots and plastic bags must not be included in the PMD waste.
Harmful waste: Out - of - date drugs（药）, used batteries, paint and oil...
Besides, if you don't need your old bikes, our school volunteers will collect them. We're going to fix them up and then give them away to kids who don't have enough money for a bike.
To find out more about recycling, you can visit our school's website.
