broken cell phone, etc

How does one dispose of a dead cell phone? Just toss it in the garbage?

Does anyone know the size of those rebars which are used in cement? Not the bars but the rectangular ones? I am thinking about 8 x 4, but may be wrong. How much would one cost? TIA.

The Telcel store in the Centro Laguna shopping center across from Walmart has a big, acrylic box where people dump their dead cell phones. Don't know where the end up after that, but here's hoping.

Thanks, I will drop it off today. Now I need to get the info on the rebar.
