Electronic waste from equipment of all sizes includes dangerous chemicals like lead, cadmium, beryllium, mercury, and brominated flame retardants. When we dispose of gadgets and devices improperly, these hazardous materials have a high risk of polluting the air, contaminating soil, and leaching into water sources.

When e-waste sits in a typical landfill, for example, water flows through the landfill and picks up trace elements from these dangerous minerals. Eventually the contaminated landfill water, called “leachate,” gets through layers of natural and manufactured landfill liner and other protection. When it reaches natural groundwater, it introduces lethal toxicity.

Health risks range from kidney disease and brain damage to genetic mutations. Scientists have discovered that Guiyu, China, has the highest levels of cancer-causing dioxins in the world. Seven out of ten children in the villages of Guiyu have too much lead in their bodies; 82% tested positive for lead poisoning. Because the drinking water is so contaminated, villagers have to truck in water from other towns.

Even with the best intentions in mind, recycling e-waste often leads to illegal overseas shipping and dumping. Devices get left in a huge pit or burned. Worse, a 2008 study from the U.S. Government Accountability Office found that some recyclers ship e-waste to third world countries under the guise of philanthropy, claiming that these “donations” bring technology to developing nations. While plenty of recyclers run reputable operations, the shadowy companies just ship obsolete e-waste to digital dumping grounds in countries like Ghana.

Frontline profiled an e-waste dump in Ghana that explored the health risks of these practices. Young children there make a living by scavenging waste to reclaim gold, silver, iron, and copper. The amount of time they spend at dumping grounds is dangerous enough; factor in these poisons and chemicals and these habits can become be fatal. Further, the U.S. State Department lists Ghana as one of the top sources of cyber crime in the world. Criminals can purchase salvaged hard drives in an open market, and minutes later they have access to the personal and financial information you left behind in discarded devices.

ABC News did an incredible investigation of one e-waste recycler based in Denver. This company, which claimed to safely recycle e-waste, wasn’t recycling it at all. Instead, they were loading all those computer monitors, laptops, TVs, and cell phones into shipping containers and sending them off to the Far East, mainly rural China and Hong Kong.

People in developing countries are paying with their lives just so we can have the next iPad. Now that you have a sense of how serious a problem e-waste poses, consider how you can make a difference with your daily decisions. It’s sobering and depressing to think about tragedy abroad, but we can change things. We can make sure our e-waste is recycled effectively, and NOT shipped off to third world countries irresponsibly.

How often do you buy a new cell phone, laptop, or TV? In these gadget-driven days, you probably upgrade your electronics fairly often. Most people don’t think twice about buying the “latest and greatest” technology. After all, companies and their marketing teams spend a great deal of money to make sure that we’re hungry for the next iPad, Xbox 360 Kinect, or LED TV.

While our hunger for electronics and technology keeps growing, what happens to our old stuff? The statistics and trends are startling:

According to Wirefly.org, the average cell phone user gets a new cell phone every 18 months.

In the U.S., we toss more than 100 million cell phones in the trash every year.

The EPA reports that over 112,000 computers are discarded every single day, in the U.S. alone. That’s 41.1 million desktops and laptop computers per year.

20 million TVs are trashed in the U.S. every year.

Only 13% of electronic waste is disposed and recycled properly.

A recent United Nations report suggests that in some countries, production of Waste Electrical and Electronic Equipment (WEEE), which includes obsolete mobile phones, computers, and HDTVs, could rise by as much as 500% over the next decade. USA Today projected electronic-waste growth and predicted that by 2014, manufacturers will produce 70 million tons of “e-waste.”

Over the recent past, the global market of electrical and electronic equipment (EEE) has grown exponentially, while the lifespan of these products has become increasingly shorter. More of these products are ending up in rubbish dumps and recycling centers, posing a new challenge to policy makers. The purpose of this paper is to provide a review of the e-Waste problem and to put forward an estimation technique to calculate the growth of e-Waste.

From its crowded streets, Hauqiangbei, looks like any other crowded Chinese shopping district, packed with streetside malls, snack vendors, and people in a sharp-elbowed hurry. But if you slip into any of these malls, it quickly becomes apparent that Huaqiangbei, located in the heart of Shenzhen, China’s electronics design and manufacturing hub, is unlike anywhere else on Earth.

SEG Plaza, at the heart of the Huaqiangbei District, doesn’t look like a paragon of green innovation when you walk into it. The main floor is packed with kiosks and stalls selling a riot of the sorts of things you find only inside your computers: cables, RAM, CPUs, and fans. They’re spooled, hung, and displayed in cases, looking not unlike a high-end butcher shop that might specialize in snakes and other coiled objects. Look up, and you’ll see nearly ten floors of similar vendors selling similar wares.

Who bothers coming here? The city’s engineers and product designers in search of the pieces and parts necessary that can help them build tomorrow’s—or today’s—electronics. Need an Intel 486 CPU from the early 1990s? Someone at SEG Plaza can get it for you in bulk. Want the motherboard from a 2002 vintage Dell laptop? The man selling Dell motherboards will ask how many you need for tomorrow.

Where does it all come from? In years past, much of the hardware in Huaqiangbei was imported from developed countries such as the United States, disassembled in infamously unsafe workshops elsewhere in South China, and then funneled into Huaqiangbei. It’s a trade that was widely misunderstood and that has saddled China with a reputation as the world’s electronic wastebasket. But the reality has long been far more complicated.

How can you safely deal with waste from your electronic devices? We have ever more technology in our homes that we also renew often. If this waste is not correctly dealt with, it can be dangerous for us and for the environment. You've surely asked yourself more than once what to do with that phone you no longer use; we are here to tell you how you can recycle your mobile, your different chargers, the compact camera that no longer works, where to recycle your batteries... how you should deal with these and other potentially polluting products, and what would happen if you didn't: A mobile phone Did you know that up to 92% of your mobile can be used to manufacture new equipment? In Spain, less than 2% of all waste electrical and electronic equipment (WEEE) is recycled and a mobile phone contains hazardous toxic components that should go to a recycling plant and not landfill.

A recent report from the United National Environment Programme warned that around 40-50 million tonnes of this type of waste are produced every year globally and it forecast 'serious consequences' from the mountains of 'hazardous' and 'toxic' waste that is piling up without any control. How can we avoid this? Easy: recycle. There are many companies that recycle and even purchase your old phone and, although not a large sum of money, it is something in addition to a guarantee that those materials are correctly repurposed and/or recycled. The closest Recycling Point to your home is one of the options.You can throw away other devices such as cameras, tablets, computers, etc. here in complete safety. Batteries The changes to chargers and batteries (laptops, mobiles, cameras) have reduced energy consumption and, in some way, their hazardous nature, although this remains high. Almost 30% of the weight of batteries is down to toxic materials such as Mercury, Cadmium, Nickel, Magnesium, Lithium and Zinc. Some of these elements are really polluting, mainly if they come into contact with water and dilute into reservoirs or rivers. These pollutants concentrate uncontrolled in the nation's landfills, with very serious consequences that are barely documented. What can we do? Once again, recycling by professional companies or leaving them at Recycling Points. Batteries We still have some devices at home that work with batteries. For this reason it is important to be aware that they contain heavy potentially hazardous metals such as mercury, cadmium and lead. Batteries are therefore considered to be special waste and are subject to specific collection and processing. Which pollutes the most? The one with the button. Leave them at Recycling Points or other collection points, such as those in advertising posts in our cities or at supermarkets and shopping centres. If these toxic components (especially heavy metals such as mercury or cadmium) are dumped without any control in nature, rainwater can carry them to underground water courses and from here, towards rivers and the sea, with a possible impact on living beings. In the event of uncontrolled fires, metals evaporate and spread in the air; when it rains, they end up in the earth and in rivers, and this is why it is so important that they are correctly processed. Most heavy metals are bioaccumulative and pass from one organism to another via the food chain. Make the most of the useful life of your electronic devices and when you decide to throw them away, do it safely!
