NHscrapman - Not sure if this company does brown boards, but they are a large recycling and refiners of metals and processor of E waste. The companies name is Colt Refining & Recycling (Merrimack & Hudson, New Hampshire), a large buyer used mostly by large fortune 500 corporations (not somebody you or I sell too!). They have a good video on YouTube, gives all of us how E-waste is processed on a large scale. There circuit board shredder at Hudson has a 4 to 5 ton capacity per hour. The video gives you some idea of the entire process from shredding, to magnetic/eddy current separation, furnace, milling, chemical stripping, to ingot. I found it interesting, noticed no brown boards!<br>

Here's the video.
