I don't think landfill is the problem but other more eurofriendly

I rather think the general trend is a move away from landfill. And as
for China, I think the move to more eco friendly ingredients would be a
lifesaver there, as old computer parts are sent to China where illegal
back street workshops maim (and even kill) hundreds if not thousands in
the recovery of lead solder from pcb boards.

One of the problems with pcb boards is the plethora of connections
that need soldering. We should have a lot more solid state devices
that can be snapped together without solder. Modern motherboards look
like they've been designed by that "Shakespeare" group of monkeys who
have taken time off from their rows of typewriters. When will a
"motherboard" be 1 inch square, consisting largely of take off points
for network, modem, printer, VDU etc, all moulded into, not soldered
onto, the package housing?

I think you have a lot to learn grasshopper

So have motherboard designers.

Yes, they're a mercury/silver/tin/copper/zinc amalgam. There's been
a "scare" about it for years.

There was a Dispatches, or Horizon, or similar on this probably
some 15 or more years ago. My recollection is that mercury
release to the environment from crematoria chimneys is actually
quite significant, at around 3g per person.

That's why the flue is fitted with an expensive "scrubber" (ooh-er!).

Apart from in Britain, of course...

So there are no strictures? Emission of mercury vapour (etc.)
is legitimate? *I think not*.

I was referring to expensive scrubbers.

You said pcbs initially ... not motherboards
