Apple has a very good and easy to use recycling program. They send you a shipping label, you walk into any FedEx and mail it to them. Simples. These days they even give you a gift card if the machine has any value.

The Apple stores accept smaller Apple products for recycling like batteries and iPods. I suspect they don't accept the larger items due to local laws on toxic waste management.

So really there isn't any excuse not to recycle your Apple product at EOL if you so desire.

You have to weigh the results of separating the glass vs. the problems with throwing away the glass. If the process leaves 5 gallons of toxic water and requires $5 of solvent, is it more economical or more environmentally sound to use the process or just throw away the screen?
