Many regions in Asia now have no drinking water because of this.

There is a 'new' mercury free process that they are using in Mongolia. It
sounds like an aqua-regia digest that I used to uise in the lab. I wopuldn't
want to do it without a fume hood and the muffling process should also be
proplerly vented. I've heard that some people use their barbeque to melt away
the cirucut boards. It's barely even worth it. You won't get
much back, right? I don't
recall most systems having high concentrations of gold...
The YouTube video I've seen suggest that you sell the boards separately but
most focused on the copper and aluminum that could be reclaimed....
