Manufacturing 1 PC Takes 1.8 Tons Of Raw Material

remy writes "Although most of it (1.5 metric tons) is water, a study from the United Nations University details the raw materials used in the manufacture of a PC and 17" CRT. That's an incredible environmental cost per PC, and a very strong argument for trying to leverage older equipment, not to mention upgrading rather than replacing."

    1.5 tons of water. But all of that gets reused eventually. I mean, it's not like it gets jettisoned into space, or converted into energy.

    I mean I suppose things like fossil fuels get converted into useless byproducts, but most of the stuff would not be. This is accounting is beyond a little suspicious. I mean, how many tons of stuff does a person eat and then shit out in their lifetime. Probably a lot more then 1.8 tons.

    And would upgrading really make that much of a difference? You upgrade a couple of times, then you need a new mobo, and after a while you need a new case to fit your new motherboard, and you practically have a new PC anyway. Its more like a gradual change to a new computer (combined with enough spare parts to build old machines) rather then large, discrete steps.

      That is true. Saying that 1500 liters of water gets "used" in the process of making a PC is pretty useless as an indicator of ecological impact.

      To be able to say something about that, you'd have to quantify how much that water got contaminated, and with what substances, what treatment it gets before it again gets released somewhere, and how and when it eventually gets re-released.

      If I start cutting granite using diamond-blades, and cools them by flushing with water from the nearby river, I'll probably "consume" enormous amounts of water, but if I let the water go into a pool where most of the dust will settle, and then back in the river, the negative ecological impact will be truly minimal.

      Much more interesting than how many liters of waters go trough my plant is instead what contamination, if any, goes into the water before it's again released. In my example that amounts to "some amount of granite-dust which mostly settles in the pool before release, and ain't *that* dangerous to begin with".

      In the case of PC-manufacture, there's obviously some amount of more harmful chemical also being released. That is something we should look at, and do our very best at minimizing.

      I just don't see how this "1800kg" metric is useful for anything at all, least of all for measuring environmental impact.

      Point is, contaminating water *is* a problem, simply "using" it in some sense or other, normally isn't. Every time I take a swim in the local lake you could argue that I "use" thousands of cubic meter. That doesn't imply the ecological impact is much above zero.

      There are several interesting points here.

      The first point of interest is that industrial use of fresh water only accounts for about 15% total water consumption in this country. Use by public consumption, such as home lawns and golf courses, wasteful water use practices (long hard showers, washing small loads of clothes or dishes without selecting proper water settings, etc.) account for over 35%. This doesn't mean that we shouldn't improve the practice of making our industries more green. It does mean that the best place to start impacting water consumption as a whole is our own homes and public landscaping.

      The next interesting point involves the quickly changing technology surrounding computers. In the near future, technical breakthroughs in OLED films, and high density storage, should allow us to reduce the physical size, weight, and composition of computers, dramatically reducing their environmental impact. In fact, using green sources for the feedstock to make computer hardware, and new technology for recycling old hardare, could reduce the power and resource consumption of PC manufacture by 50%-75%. This will result in saving hundreds of billions of tons of water anually.

      The last interesting issue, is that water consumption is not actually the issue. Or at least not directly. The issue has never been the direct consumption of water so much as it's been moving water from places that have to places that don't. Every one of those tons of water has a huge cost in fuel needed to transport it from source to spiggot. Add up the cost both economic and environmental for the maintainance and upkeep of the delivery infrastructure, and you're beginning to look at a serious expense for doing business. With the depletion of western aquifers, set against the stiff competition for water for agrobusiness, and the growing population in arid regions (read that as an unprecedented need for water in places that have none of their own to quench a thirsty populace), and the clear and urgent need to conserve a shrinking resource becomes self evident. In the near future, any sane business program will include the environmental cost, because in the end, we all pick up the tab for maintaining an environment that is sufficiently healthy to support basic human endeavors.

Fortunately, LCD monitors have more than balanced this out, at least for now, but with 150W CPUs coming before year's end, I don't know how long it will last.

Why have power supplies jumped up to the 400-450W range? Because there's a very vocal gamer market that has been driving PC hardware development. In reality, high-end PCs games don't even sell all that well. The huge selling games are things like The Sims and Roller Coaster Tycoon and generally not cutting edge 3D games.

You have people buying the P4 Extreme Edition solely because they spend most of their time doing video compression.

Newer models provide more computation per watt than older models, so old ones should be recycled and the materials they are made of re-used more efficiently. I know of at least two people that went bankrupt assuming that re-using old computers was commercially viable. That said, there is a place for old computers right now, but I hope such niches are filled by modest-performance, ultra-low-power new machines.
