[comp.society] Environmentally safe computers?

riddle@woton.UUCP (Prentiss Riddle ) (07/20/87)

I've been hearing more and more criticism of the purported benefits of the
"computer revolution" lately from those who point out that the electronics
industry, despite a lot of claims to the contrary, is a very dirty one.  As
one book I have read recently complains:

    Communities dominated by the computer industry are plagued with
    severe groundwater contamination from cyanides, arsenic, toxic heavy
    metals and a wide range of carcinogenic chemical solvents, all
    essential ingredients in the manufacture of silicon computer
    chips... 
    
    The electronics industry claims a rate of occupational illness two to
    three times the average for manufacturing industries, with frequent
    complaints of severe acid burns, chemical-induced disorders of the
    nervous system, kidneys and liver, menstrual irregularities and
    frequent miscarriages.  The most routine and the most hazardous
    operations are often moved to countries in Latin America and
    Southeast Asia, where local water supplies are routinely destroyed
    and young women workers find their eyesight and reproductive health
    to be permanently damaged after just two or three years of assembling
    computer chips.

    Brian Tokar, 1987.  The author cites as his sources a March, 1985
    issue of "Science for the People," an article in the November, 1984
    issue of "Sierra," and the Silicon Valley Toxics Coalition, 277 W.

My question is this: are these problems inherent in the manufacture of
computers, or are there trade-offs involved?  Assuming that there were a
desire to do so, would it be possible to manufacture computer components by
environmentally safe processes, given certain increases in cost and decreases
in performance?  And for those of you with a taste for a good deus ex
machina :-) , are there any breakthroughs looming on the horizon which might
create a shift to clean computer technology?

There are some trade-offs, but it takes pioneering to discover what
those tradeoffs are, and I am not certain many companies check out all
tradeoffs in manufacturing.  Especially in economically competitive
markets.

One thing to point out when I was working for a thin-film lab.  The
basic ingredients of SiO2, Cu, and Gold are not the big problems, the
problems are the tools used to work with them: Gold is chemically
difficult stuff to work with and Aqua Regina is very hazardous stuff
(recalling the lecture we were given to handle it).  HF to etch glass is
also pretty dangerous.  {So we can't argue that optical computing will
be `cleaner' for instance.}  So it is frequently the tools which are the
problem, many are irreplaceable.  This problem also promises to get
worse as we work with more and more difficult compounds: GaAs, some of
the rare earths. (major point)  And the lead (not Pb) times to detection
are long and the materials effects are not well understood.  The
quantities, however, are probably smaller than the petro-chemical industry
(growing up not to far from where Dow Chemical made naplam in the
1960s).  Ask this question again in 2020.
