July 19, 2002 -- As televisions, computers and monitors and cell phones become disposable commodities to be replaced by newer, better models every few years, the problem becomes what to do with the old ones. The equipment that ends up in landfills can pose environmental hazards if the lead and other toxic materials in them leach into the soil.
A 1999 study published by a University of Florida scientist showed that cathode ray tubes -- or picture tubes -- found in color
monitors and TVs leached, on average, more than four times the amount of lead the Environmental Protection Agency defines as hazardous.
As NPR's Emily Harris reports on Morning Edition, the findings of this fairly simple study turned out to play a key role in the fight to keep electronics out of landfills and intensified a controversy over who should pay to recycle them.
Marianne Horinko, the EPA's assistant administrator for solid waste, says the results of Associate Professor Tim Townsend's study were a useful guide to determine potential hazards.
"Having this data from the University of Florida study gives us the information we need to say that indeed, disposal of these end-of-life electronics may pose risks that we are very concerned about," Horinko says.
Previously companies determined whether their discarded computers should be handled as hazardous. Consumers didn't have to bother with any such regulations. But the study prompted some states to act. Massachusetts was the first to ban all CRTs from landfills, though saving space was more a concern than potential lead leaks. But a year later, California closed its landfills to all TVs and monitors, based on Townsend's study.
Since the landfill ban, CRT recycling has become a big business in California. At a Sacramento facility owned by Australia-based HMR, workers dismantle hundreds of computers and TVs a day. They separate out the circuit boards, the wires and the plastic to be sold as commodities.
CRTs are crushed by a special machine. The glass is reused for new picture tubes or sent to smelters that process lead. But people getting rid of old computers or TVs have to pay for this special handling. In California, it can cost between $20 and $65.
To pay for a recycling infrastructure, state lawmakers have proposed adding a special fee to the price of new computers. But computer makers say such fees would be too hard to collect from all computer sellers. Heather Bowman of the Electronics Industry Alliance also says it's not fair for people buying computers to pay to recycle old ones already stacking up. "We think that to be more fair, it's got to happen when you're ready to get rid of the product," she says.
A group of manufacturers, environmentalists and government officials are trying to create a national voluntary computer recycling program. The biggest obstacle is how to pay for such an infrastructure. Meanwhile, Rep. Mike Thompson, D-Calif., has just introduced a bill to put a maximum $10 fee on the purchase of monitors, CPUs, laptops and potentially other electronics. The EPA would use the money to give grants to organizations that refurbish or recycle old computers.
Pressure to do something safe with old computers grew with recent reports that many U.S. discards are taken apart in Asia with no precautions for health or the environment.
"No company wants to see its products being stripped of toxic metals by hand over an open fire, or on a mountain of junk where kids eat and play," Harris reports. Major manufacturers are offering take-back programs, often for a fee. Dell is contracting with U.S. prison labor to dismantle customer discards.
But at the same time as they find alternatives to landfills, manufacturers says they don't believe there's a threat of toxic leaks from trashed CRTs. They point to Clark Akatiff, long-time landfill supervisor in Palo Alto, Calif., who says landfills are a safe and efficient way to deal with the waste.
Akatiff says that even with tens of thousands of CRTs buried in his landfill, about 80 percent of the monitoring wells surrounding the facility show no evidence of lead. A few show trace amounts, he says, levels that have also been also been detected in other California landfills.
But Townsend, the Florida scientist, says the "sustainable" solutions -- making new computers out of a discarded ones -- are the answer to the problem.
On commission from two regional EPA offices, Townsend is now studying toxic leaching of other electronics. This summer, his graduate students are tossing keyboards and computer processing units into a big barrel of acid. Chopped up cell phones go get tumbled in smaller jars. This time they'll look for more residues than lead, including cadmium and bromide flame retardants, which accumulate in fat like PCBs, and for mercury, which is used in laptop screens.
