For the sake of the generations that come after us, we really should not dump valuable material into space. I somehow doubt the electronics in space would be recovered and recycled properly.

Nothing is recycled properly. Recycling was a story told to ease consumers minds so they keep on consuming. The stuff you throw away ends up on a landfill, in the sea, or on a ship to someplace else where it gets burned and then buried. Sending it to space makes absolutely no difference.
