Does anyone have any guidance (hard facts would be especially useful !) on the potential environmental hazards of recycling teflon coated metal?

I received the below email and don't have any in-depth knowledge on this.

Thanks,

Have been looking into this a little because of current controversies over Teflon and DuPont.

Harmful emissions from PTFE-coated pans (Teflon is the DuPont brand but is not the only source) are documented at over-heated pan temps well below the melting point of aluminum. So one can assume that the melting-down process would not be clean. But scrap Al often has grease, paint, and other fume-producing nasties on it. I doubt that most aluminum-melters are in the habit of taking any special precautions for Teflon pans in the mix.
