The Environmental Cost of Silicon Chips
Col. Panic writes "Scientific American is running a small story about the amount of material required to produce silicon chips and the potential hazards of associated toxic chemicals." This combined with coltan mining processes sure paints a dark picture of the chip industry.
In line with protecting the environment, I choose to use environmentally friendly products in my cpu, such as compost and renewable timber.
Of course my computer doesnt work, but at least i'm helping the environment.
Be you Admins? nay, we are but lusers!
I'm NEVER buying a CPU from DeBeers' ever again.
a typical two-gram chip takes 1.6 kilograms of fossil fuel, 72 grams of chemicals and 32 kilograms of water Does anyone know if this 'water' is resuable? Is it just for cooling?
I can't seem to find the link, but recently Wired published an article in their dead-tree magazine about replacements for many of the hazardous chemicals used in chip production. There are new ideas which will make most of the run-off biodegradable, and some companies are looking into building new factories to support these new techs in the long term. But there won't be any environmentally safe process anytime in the near future.
Developers: We can use your help.
What are the alternatives. I understand that people compain about other people using cars that use excessive amounts of fuel, but there is no better way to make microchips yet, or is there?
Important safety note: When working in such a place, always wash your hands up to the elbows before going to the bathroom, or rubbing your eyes. I've been told that sulfuric on the willy is an unforgettable experience...

or, more likely--this is a reminder to all that are working on this sort of stuff to consider the environmental consequences of their actions.
basically, you could write the same case about the auto industry 30 years ago. then, people started becoming interested in environmental issues, and attitudes within the industry changed. While we're not at ideal yet, we're at least at where even SUV owners have embedded in their minds somewhere that such gas guzzling is not the best idea.
Complex chemical compounds can be harmful to your health and to the environment! (Wow!)
And, in related news, Bill Gates is incredibly rich and Saddam Hussein may not be such a nice guy after all! (Amazing!)

while there may be some environmental issues concerning chip manufacture. The benefit that the microprocessor has brought to human society far outweighs any environmental cost.
The GeekNights podcast is going strong. Listen!
Okay, it's not very funny. Don't laugh.
. . Its just like any other period of mass adoption of technology in Human history . . I mean, look at the way England and the United states manufactured materials before the beginning of last century . . Smokestacks belching unfiltered by product into the skies and run-off pipes dumping raw sewage into the rivers and seas . . There's a honeymoon period where everybody's eating up the tech and the whole issue of 'cost' other than the bottom line for materials really isn't taken into account . . Only sometime after the initial binge do people finally standup with that hangover and see the potential damage that the consumption really causes . .Now Environmentalists will kvetch about it for a while and we'll go through the cycle of upgrading the process so its greener . . .Its the beauty of innovation :) . . And plus, its pure entertainment to watch both sides hurl statistics at each other with such vicious aplomb . . ;) . . .
The only thing that you can do - tax those who do not clean up their act.
A large company will allways try and producs cheaply . If it becomes too expensive to produce chips using "Dirty" methods you an just bet they will find "Clean" methods to reduce their margins.

Last time I checked, *everything* we do has some form of by-product that could be considered waste. Heck, I can turn a bowl of beans into a mean ol' cloud of gas.
What they fail to mention is the benefit of the chip manufactured. Cost/Benefit - sound familiar?
This article is just reason # 87 why I cancelled my SciAm subscription earlier this year after 15 years of subscribing. They've veered from true science and now feel the need 'preach' environment, evolution, abortion, etc. in the monthly Editor's Perspectives (and various articles).

at least from the intel press release :D
The new manufacturing technology enabled by the 300-mm technology also provides significant benefits from an environmental perspective. The chips manufactured in Fab11X will require less water and generate fewer emissions per chip than other fabs. Water and chemical use will be more efficient. When compared to a 200-mm facility Fab 11X will produce 48 percent less volatile organic compound emissions, use 42 percent less ultra pure water and will use approximately 40 percent less energy.
Yes but it doesnt have to be those countries that stand up to them. The consuming countries can do it just as effectively. The US and/or Europe alone could do it by simply saying "Show us an audited trail of how you produced these chips. For every gram of crud you produce thats an extra 10% sales tax".
The manufacturers need these markets. If the markets dont like the manufacturers methodds, they can force them to change.
<fnord>OBEY</fnord>
One thing I've often wondered is whether a typical solar cell produces more energy in its lifetime than it takes to manufacture it?
The problem with reports like this is that you never know precisely what the unbias facts are. In a world where the majority of conservationist organizations are run by zealots who practically hate civilization altogether, you never know who you can trust.... and it only hurts their cause. In this case, nobody is going to stop using computers or even pay attention to this article.
Don't worry, our grandkids can clean it up. Luckily, they'll have plenty of oil wealth to help them do it.
No, wait...
</sarcasm> aside, this just goes to show that capitalism means cutting off your nose to pay for your facelift.
Oh, sorry, my <sarcasm> must have been nested, along with a <mixed metaphore>. But really, why is this a suprise to anyone? Our entire economy is based on the premise that the lowest bidder is always the best one. Without artificial (read: gubmint) controls (which we're not going to get under undisputed reign of George II), using the cheapest process without regard for the consequences is inevitable. It's actually the fiduciary duty of the execs in these industries to do this! If they were to switch to using a cleaner (but more expensive) process, they'd be sacked at best, and quite probably sued by their shareholders.
If you were blocking sigs, you wouldn't have to read this.
It's interesting that it takes just about the same 1.6kg of fossil fuel to drive 10 miles to a store and back to buy that chip. Curious.

Every time I use conferencing over the internet, I am saving (typically) about 30lb of Diesel (and it would have been nearer 45lb of gas in my last car)
I'm not arguing that we should ignore the environmental costs of technology - places like the former Communist block and Texas are unpleasantly polluted as a result of doing just that - but that we should look closely at the costs and benefits. Given the potential of global warming and the eventual runout of oil, the more we use silicon to reduce the number of boring journeys we have to do, whether by mobile phone, networked computer, or whatever, the better it is going to be for us.
And for those who don't already know - substances like sulfuric acid and HF are widely used in the petrochemical industry. And what happens to all the sulfur they have to remove to get low-sulfur fuel? It surely doesn't get fired into space by a rail gun.

He means "There ain't no such thing as a free lunch" (TANSTAAFL). This acronym was introduced by Robert Heinlein, who is sometimes also cited as the originator of the phrase as well. It features in "The Moon is a Harsh Mistress" and several of his other books as well. Robert Heinlein was one of the most popular science fiction authors of the 20th century, especially in the US. It's not such an obscure phrase, given Slashdot's audience.

That explains why everyone here drives a Yugo, eats Big Top-brand cereal, and writes their posts from an eMachine.
here in norway we allready have enviroment-taxes on things like tv's and pc's.
i only wonder if the taxes actually will help lower the pollution to the environment.
If you read the NYT article it makes it sound more like those Africans would be sitting around starving or something if it wasn't for the coltan mining jobs. I mean god forbid someone should do manual labor in the outdoors... it's just horrid!
I'm not saying that people should be digging in animal preserves, but that is 'illegal' over there.
If you read the article, the author seems to think that self-righteous bans on material from certain countries, as well as the tech slump are causing more harm to people then the mining system.
autopr0n is like, down and stuff.
Someone said elsewhere I was missing the point, and that silicon manufacturing processes need to improve. OF COURSE. But what drives the improvement is that it is invariably CHEAPER in the end to make things using best environmental practice, unless the State gives the manufacturer a dispensation from paying the costs of the environmental damage - a statist subsidy. And it is usually cheaper anyway because of the savings on materials and consumables. As an example, one project I looked at (to prevent the discharge of cesium by monitoring the composition of a bath and reprocessing it) had a payback of about a week based on the cesium savings alone: the management simply didn't know what was going on in their own plant and had accepted the costs blindly. In another project, a closed loop treatment plant turned out to be cheaper than open-loop because the cost of the electronics was more than offset by the smaller outlet holding tank that was required. I could go on and on...but then, I got into the computing business because you can, actually, do much more interesting things with silicon than make Word or Quake run faster.

or perhaps a 'Regretfully True'
judging by some of the posts here there are a lot of people who think it doesn't really matter. As long as their CPU isn't burning a hole through their desk, who cares.
And when the computer's thrown away and the components start to leak out... ah well, it isn't my computer anymore. I threw it away. I have this new shiny computer with twice the RAM and 120GB RAID-5 blah blah blah blah blah...
My point isn't that we techies should stop using computers, but that we should at least be a little concerned about what it's costing us in the long run.

It breaks my pluginses, my precious!
HF, H2SO4, etc. are nasty, but easy to neutralize. If you neutralize them, they become aqueous solutions of relatively benign salts. The problems are more with organic solvents that have to be burned at high temperature and with heavy metals that cannot be rendered safe, but must be segregated from the environment.
