Organizations Prevent E-Dumping in Developing World


In 2008, Hong Kong authorities stopped 41 U.S. ship containers trying to carry 1.4 million pounds of "e-waste" and 82,000 pounds of lead into the region for disposal, according to USA Today.

While governmental authorities can prevent some of this technological refuse from entering their country, Jim Puckett, the head of non-profit, watchdog group Basel Action Network (BAN), says that they cannot catch it all. That's where activist groups like BAN step in.

Due to the efforts of BAN, and other organizations like it, law has come to the formerly Wild West-style of U.S. e-waste policy. For one, the federal government has gotten involved, the Government Accountability Office acknowledging and criticizing the improper disposal of U.S. e-waste in India and China. BAN has also convinced many corporations to sign no-export pledges, rallied significant support for setting standards on e-recycling, and encouraging companies to audit potential recyclers for their eco-friendliness.

That being said, tons of e-waste leave the U.S. every year.

'60 Minutes' Explores America's Massive E-Waste Exports to China


Any self-respecting gadget hound knows that China is responsible for packing millions of shipping containers with the consumer electronics we crave. What you may not know is what we ship in return: our waste for recycling. Of growing concern is e-waste, resulting from the deluge of PCs, cellphones, televisions and crapgadgets we churn through at an accelerating clip each year.

While domestic recycling programs are good-intentioned, often the most toxic of our e-waste is shipped illegally back to China and boiled down for its precious metals under some of the most crude conditions you can imagine. When faced with the choice of familial poverty or the slow accumulation of poison in their bloodstream (for $8 per day), it's not hard to imagine what many rural Chinese people will choose.

So while we give Greenpeace's self-congratulatory promotions and oft-subjective "Guide to Greener Electronics" company ratings the occasional hard time, its attempts to raise e-waste awareness are commendable. Now go ahead, check the video from 60 Minutes's intrepid reporters after the break and let the guilt wash over you (especially after you see how some particularly angry e-waste workers try to jump the CBS news crew).

Update: As noted by reader Jason, a more thorough (and disturbing) exploration of these e-waste dumps can be found in a Current TV video shot last year in the same region. [From: CBS News]

Super Efficient Material Converts Car Exhaust to Energy



Your car engine wastes up to 75-percent of the power it generates -- but a team of Ohio State University researchers thinks it has found a way to capture a lot of that wasted energy and convert it into electricity.

The promise is in a new material they've developed, called thallium-doped lead telluride. (Isn't that a black diamond trail at a Colorado ski resort?) This is twice as efficient at converting heat to electricity as any previously developed material.

The research team's lead, Joseph Heremans, says the thallium-doped lead telluride can convert a car's wasted heat into energy without causing pollution. "The material does all the work. It produces electrical power just like conventional heat engines -- steam engines, gas or diesel engines -- that are coupled to electrical generators, but it uses electrons as the working fluids instead of water or gases, and makes electricity directly."

Some experts argue that only about 25-percent of the energy produced by a typical gasoline engine is used to move a car or power its accessories, and nearly 60-percent is lost through waste heat -- much of which escapes in engine exhaust. A thermoelectric (TE) device can capture some of that waste heat, Heremans said, and it would also make a practical addition to an automobile, because it has no moving parts to wear out or break down.

Heremans' team didn't just try random new types of metals or coatings for their research -- the team is also working on the nanotechnology and quantum level. "We hope to go much further. I think it should be quite possible to apply other lessons learned from thermoelectric nanotechnology to boost the rating by another factor of two -- that's what we're shooting for now," he said.

If Hereman's next announcement is for a flux capacitor (1.21 gigawatts!), we'll know we've crossed over from science advancement to science fiction. Either way, with rising fuel costs, we hope car makers take notice of Hereman's breakthrough. [Source: BetaNews]

Most Cell Phones Still End Up In Landfills, Polluting the Environment

Yesterday, the New York Times Magazine ran a fairly comprehensive piece on the life cycle and environmental impact of mobile phones. The story detailed how many phones are reused, how many others are broken down and "mined" for useful metals such as silver and gold, and how still others – most others, in fact – end up in heaps of discarded electronics, left to leach often dangerous ingredients into the earth, water supply, kids' blood streams, etc.

Some businesses and watchdog groups are doing their darnedest to offset this problem, or at least delay the inevitable discarding of the dead phone, but the report overall is a sobering one.

The main point raised: Despite our love affair and attachment to our mobile phones, we still use, discard and then buy new ones at an alarming rate, with little regard for the environmental impact.

Such eco-carelessness isn't limited to mobile phones and e-waste is not a new issue to the consumer electronics industry. But while mobile phones are small compared to old CRT TVs and computer monitors, they are in use everywhere. In some African nations, where landlines are difficult to build and maintain, mobile phones are the only way for someone to have reliable communications.

As the reporter notes, "There is no heaven for cellphones."

Facebook Costing Businesses $264 Million Daily in Lost Man Hours

Workers Can't Stop Wasting Time on FacebookVanishing staplers aren't the only employee-related phenomena bleeding the corporate world dry. According to a new study by U.K.-based employment law firm Peninsula, roughly £130 million (or about $264 million U.S.) is lost per day by British corporations due to office workers dillydallying on Facebook. That's the equivalent of 233 million employee hours per month. And British companies aren't the only ones suffering: Australian security firm, SurfControl, conducted a similar study of its own and found that Facebook was swallowing $5 billion (Australian) a year, or the rough equivalent of $4 billion U.S.

The loss of cash and man hours is starting to garner attention amongst businesses, which are looking for a way to deal with the social networking phenomenon. Many companies have already started blocking the site in an effort to regain lost productivity and discourage employees from wasting of time. Several companies in America already block sites such as Facebook and MySpace and sometimes even block access to personal e-mail. They consider these measures ways of preventing information leaks and maintaining a productive working environment.

Gabbing around the water cooler is dead. In its place is updating your Facebook status.
