The wastage and damage to the environment in China has no limit. Just attend those big sport events, concerts or parties. You all get those funny sticks that flash, shine, blink, glow etc.
Cute.
The only problem is: they are to be used once only and thrown away. Many are of such poor quality they often fail to work. Even if you want to re-use them, difficult. So they mostly all end up in the garbage after the party and obviously, this being China, don’t expect “recycling”.
One of the worst examples is what we got attending the New Year Party of the Beijing Development & Reform Commission, see picture.

The sticks, made of plastic, contain 3 small cell batteries, a small electronic circuit with a switch and LEDs (I think). Works actually well but the problem is they promptly are thrown away and the environmental impact is serious. Just imagine thousands of those ending up in landfills every day. At least I brought them home and will take out the cells if I throw them away.
