A whisker of doubt

Protection of the environment was the ticket on which RoHS in general -
and
this substitute lead-free technology in particular - was originally sold
to
an unsuspecting world. It seems to me that those who make up this
eco-legislation (as they go along, I suspect) are now discovering the
error
of their original concept as to why the mature and proven lead solder
technology needed replacing, and are now seeking to bury that error in a
different concept altogether. I can't remember ever before seeing any
reference anywhere to RoHS being primarily to improve the ease and safety
of
WEEE recycling, rather than as an environmental issue.

So, far from this article "refuting the gloom and doom", I think it serves
only to further highlight the well known shortcomings of lead-free solder
technology, and unfortunately for Mr England's case, I don't believe that
his letter holds a candle to the two from the other side of the coin,
which
preceded it.

What exactly can be recycled from say a PC?
As far as I can see the steel casing and perhaps some copper if it is not
too widely distributed , fragmented, needing human separation and plastic
separation environmental problems.
RoHS for recycling implies component level recycling - recycling 3 to 10
year old pc ICs - pull the other one.
Failing that, recycling processed sand and hard plastic after desoldering,
very unlikely. Leaves just the solder itself, which is just as recyclable
with or without lead presumably .
