It turns out a lot of things that are collected to be recycled in the USA are in fact sent overseas to be processed. Even things like plastic drinking bottles. Things like old electronics are especially bad since the people harvesting metals and other valuable bits from the electronics are exposed to a stew of toxic gases and chemicals.
Before recycling your next electronic gizmo, you might want to check whether your local recycler is has an e-Steward certification. I wonder whether PC Recycle and other local recyclers used by companies like Microsoft are e-Stewards?
