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. [Source: "The Green Alternative: Creating an Ecological Future" by 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. Hedding St., San Jose, CA 95110.] 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? --- Prentiss Riddle ("Aprendiz de todo, maestro de nada.") --- Opinions expressed are not necessarily those of Shriners Burns Institute. --- riddle@woton.UUCP {ihnp4,harvard,seismo}!ut-sally!im4u!woton!riddle

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. --eugene miya NASA Ames Research Center
