The next major tech fallout could be environmental, as computer use increases and consumers get rid of obsolete equipment.

Experts warn that if more viable ways to recycle or re-use old electronics and computer gear are not found, much of the cyberjunk will end up in community landfills, where it poses risks to health and the environment. The issue has corporations, government officials and environmental advocates brainstorming for solutions -- and debating about who should pick up the tab. According to the National Safety Council, the number of PCs deemed obsolete in 2002 will exceed the number of new PCs shipped. With few recycling programs now in place, the U.S. Environmental Protection Agency estimates that computers and other electronic equipment already account for about 220 million tons of waste per year in the United States. What is worse, say environmental advocates, is that older equipment contains large amounts of lead, mercury and other heavy metals that pose health hazards if not disposed of properly. The latest response from the high-tech industry came last week, when computer and printer maker Hewlett-Packard announced an equipment recycling service for consumers and businesses. The Palo Alto, California-based company said the service -- part of its ongoing Planet Partners program -- includes pickup, transportation and evaluation of items for possible re-use or donation, as well as recycling. HP said that computer gear from all manufacturers will be accepted, and consumers can purchase the service online for a fee ranging from US$13 to $34 per item, depending on the type of product being returned.
