========================  

Computers are ranked as the nation's fastest-growing category of 
solid waste by the Environmental Protection Agency. And one of its 
most dangerous.  

(Anita Hamilton/Endicott, Time Magazine)---In a cement-floored 
warehouse in upstate New York, half a dozen women sit hunched 
over computer workstations. Holding a heat gun in one hand and 
metal tweezers in the other, they pry silicon chips from circuit 
boards like dentists extracting little metal teeth.  

Down the hall, a jumble of bright green motherboards spills out onto 
a conveyor belt headed toward a shredder that will rip them to 
cracker-size pieces of plastic. And around the corner, a clean-cut 
guy in a black work smock takes a big hammer and smashes one 
hard drive after another before tossing them into a huge bin marked 
ALUMINUM.     

No, this is not a PC factory gone berserk. This is the place where old 
computers go to die. IBM's Asset Recovery Center in Endicott, N.Y., 
is one of the largest PC junkyards in the world. Some 40 million lbs. 
of computers are dismantled here each year.     

It hardly makes a dent, however, in the annual bumper crop of dead 
computers. Every year an electronic trash heap nearly as tall as 
Mount Everest is tossed into garbage cans, stashed in garages or 
forgotten in closets.  

Some 500 million PCs will be rendered obsolete by 2007 in the U.S. 
alone--abandoned by users who have upgraded to faster and sexier 
machines--according to a report by the National Safety Council. 
Computers are ranked as the nation's fastest-growing category of 
solid waste by the Environmental Protection Agency.     

And one of its most dangerous. Old PCs contain lead, cadmium, 
mercury and other unsavory components. Yet only 10% of the 
machines are recycled. Many of them find their way into landfills 
and incinerators, where they can threaten the environment. That's 
why the European Union has drafted rules that will hold 
manufacturers responsible for recycling their wares by 2008.     

To fend off similar legislation here, U.S. manufacturers are 
scrambling to devise recycling programs of their own--and hoping to 
make a buck while they're at it. Last November, IBM launched the 
first nationwide program; it charges computer users a $30 shipping-
and-handling fee to take even an ancient PC off their hands. Hewlett-
Packard plans to launch its consumer-PC take-back program in 
March. Regional efforts--such as Sony's "recycling days" begun in 
Minnesota last fall--have sprung up from Oregon to New York.     

They face some consumer resistance. It's hard to pay a stranger to 
cart away a computer you bought for $2,000. Yet by the time you're 
ready to part with that machine, it's often so obsolete that no school 
or charity will take it. If you put it on the curb with the trash, however, 
it will end up in a landfill, where toxins could leach into the soil.     

A recycled PC, on the other hand, is literally a gold mine. Pentium 
and other processors have golden tips. A computer's main circuit 
board, fashioned from copper and fiber glass, is studded with silver 
and gold connectors. A steel frame keeps the unit sturdy, and 
aluminum or copper heat sinks prevent the cpu from overheating. 
The outer plastic case can be recycled to make everything from 
pothole filler to pencil holders. Even the cords dangling from the 
back have rich copper wiring that can be reincarnated as pipes, 
pans or furniture.     

Yet for all the precious metals and other reusable parts, it's still 
tough to make any money recycling PCs. Minus the cost of 
processing, the average used system is worth a measly $6 in raw 
materials, according to electronics recycler Envirocycle in 
Hallstead, Pa. The monitor is worth just $2.50.  

When IBM announced its consumer-PC recycling program last fall, it 
decided to have the carcasses shipped not to its 700,000-sq.-ft. 
recycling center in Endicott (where it mines corporate PCs for parts) 
but to an independent recycler 30 miles away. The reason: 
"Typically all that low-end stuff is not profitable," says Lawrence 
Yehle, operations manager at IBM Endicott.     

So low is the material value of each PC that the first step in 
recycling is to try to resell the machine--either whole or for its 
working parts. IBM resells a third of the used equipment it gets back 
from corporate leases in online sales and auctions. "It's a profitable 
business for us," says Joe Lane, general manager for global 
financing. Old chips get second lives in electronic toys. Outdated cd-
rom and hard drives are reborn as replacement parts.     

When components are too old to be salvaged, IBM ships them to 
specialists in plastic, metals and glass. At Envirocycle, which does 
monitors, the plastic cases are popped open, the power cables 
chopped off and the circuit boards removed. Next the glass is 
crushed into pieces and stripped of various coatings so it can be 
sent to monitor makers that will re-form the rubble into new displays. 
 

MBA Polymers in Richmond, Calif., feeds whole keyboards and 
joysticks into its machines. The metals get siphoned off, then the 
plastic is melted into tiny pellets, which are resold for use in 
industrial flooring, auto parts and office supplies.     

Because metals are especially valuable, Hewlett-Packard mines its 
own. Step inside its 200,000-sq.-ft. warehouse in Roseville, Calif. 
(which it runs with partner MicroMetallics), and you will see 
computers stacked three stories high. A hulking blue machine 
swallows PCs and mainframes whole, grinds them up and a few 
minutes later spits them out in quarter-size pieces. A system of 
magnets, screens and electrical currents separates out aluminum 
and steel, while the remaining mixed metals go to Noranda Inc., a 
copper smelter in Quebec.  

The metal scrap HP produces by the ton has a higher percentage of 
copper than ore excavated from the ground, according to Bob Sippel, 
Noranda's vice president of recycling. Last year the Roseville 
operation retrieved more than $5 million worth of gold, copper, 
silver, aluminum and steel.     

As recycling ramps up, computer manufacturers are discovering new 
ways to make the process more efficient. Metal screws are being 
replaced with snap-open panels for quicker dismantling. Lead solder 
used to fasten parts to circuit boards is giving way to safer tin, 
silver and copper alloys. Spray-on flame retardants, which can be 
toxic when recycled, are being replaced with metal paneling. And 
those annoying plastic shipping peanuts are being replaced with 
packing material made of water-soluble starch.     

Still, critics insist that more work needs to be done. "The efforts in 
the U.S. have been chaotic and will not be successful until 
companies start picking up the excess costs," says activist Ted 
Smith of the Silicon Valley Toxics Coalition. In their defense, U.S. 
manufacturers insist that government and consumers must share 
the responsibility--and the cost.     

"I can't go into people's houses and take their computers out for 
them," says Renee St. Denis, environmental-business-unit manager 
for HP. That's true. But if consumers aren't given sufficient incentive 
to turn their computers in, then all those recycling initiatives--not to 
mention all those PCs piling up in closets--could simply go to waste.
