Harvey,
You know I have been against lead free from an environmental point of
view (and have published papers proving aspects of that), but I must
come to Ron Lasky's defence.  Decreasing the number of lead-containing
boards that go into a recycling plant will undoubtedly make things
better for the workers.  The question is how much and is it worth it?
For instance, if we are talking about a first world, well run plant like
the Noranda one in the greater Toronto area (which I have toured twice),
it makes little difference whether the boards are leaded or lead-free.
But if we are talking abut a less well run place...  So Ron's assertion
is not false, he should have just used a few qualifiers.

Subject: [LF] "Safe" recycling Printed Circuits to reclaim solder--does
that really justify Lead-Free?

The latest lead-free rationalization claims that it makes recycling
"safer".  None other than Dr. Ron Lasky says so.
One unintended consequence of l-f will demonstrate again how false is
that
assertion.

Silver in the mix will finally incentivize commercially viable
recycling,
that is true. But the enormous mass of legacy electronics with tin-lead
solder is all around us. Even today, penetration of lead-free solder is
probably still less than 50%. Some boards with lead will find their way
into the same recycling plants as boards with silver.

Boards will be ground up and and the metal content melted out for
separation of silver,lead, etc.  Companies like Noranda have been doing
this for many years. But there's an better example, primary silver
extraction.

How is the tiny component of silver separated from the preponderant lead
when they come all mixed from the mine?  That the way it's done and with
today's pollution controls, done safely to personnel and to the
environment.  Propagators of this latest lead-free lie will have a hard
time proving otherwise.

The real toll to the environment of their lead-free efforts will be an
enormous increase in mining of silver and tin to replace lead.  They
have
the gall to claim that they are care about safety or the environment.
