In Macklemore's song "Thrift shop" a broken keyboard is used as an expression for something completely and utterly useless ;-)

If you buy electronic equipment there should be a small piece of paper with a declaration of which nasty substances are included in the item.
It usually is in the form of a small spreadsheet. With on top the substances usually in this order:
 Pb (Plumbum) which is Lead. (Used in all soldered contacts thus in nearly all electronics)
 Hg (Hydragyrum) which is Mercury.
 Cd which is Cadmium. (Was used a lot in the old nickel-cadmium batteries)

 Cr-VI which is Chroom-6.
 PBB which is Polybrominated biphenyl. This is a flame retardant in plastics which are getting hot.
 PBDE which is Polybrominated diphenyl ether. This is a flame retardant in plastics which are getting hot.
These substances are simply poisonous and can cause cancer and hormone imbalance.

In backstreet recycling they are not into recycling these substances or safe disposal but interested in the other elements that have a value which are mainly copper and gold. All the above substances are still getting in the environment. Proper recycling takes care of the nasty substances that don't have a value but cost a lot to dispose of properly.

Get realistic. There is nothing special in a keyboard like ""Heavy metals such as lead, mercury, cadmium and beryllium, as well as hazardous chemicals". If they arive in Beijing it will be dumped there.
The things that should be discarded with special care are the actual electronics.

Common problem in China. Things are represented as actual being there while they are still in the planning and building stages.
Depending on your phone navigator you might be routed over roads which are still under construction. Especially Apple is doing this.
I have quite some maps which roads on it that are simply not there. They is no indication that they are still under construction.
