What is Done with Discarded Computers?

disc comp bWhen it comes to technology, planned obsolescence has been the name of the game for over a decade. Cell phones, laptops, desktop computers and even wearable processors like Fitbits are not meant to last forever; they’re meant to hit the market in pre-planned iterations. When a new version of a particular model comes out, it’s normal for manufacturers to have engineered them with the sales for future versions in mind; that means it’s good if that version breaks in time for a new sales quarter.

So where does discarded technology go after it’s disposed of? What is it about electronic waste that makes it so important to sort it and keep it from normal landfills? What is done to adjust for the disposal needs specific to electronics? Read on to find out.

The major disposal issue that old electronics present is rooted in the elements of which they are created. A typical personal computer (which contains many circuit boards) may contain up to eight pounds of lead, along with lower but significant levels of mercury, arsenic, cadmium, beryllium, and other toxic materials. Electronics also tend to use some member of a common but poisonous family of flame-retardant chemicals. All these materials are all toxic at varying exposure levels (though there is no safe level at which a person can be exposed to lead). They can cause major health problems, and in some cases death, in the event of a severe enough exposure.

disc comp1If all of these materials were to collect in a landfill, it’s not hard to understand how damage to human health could ensue. Unfortunately, no imagining is truly necessary; studies have found that in America, e-waste accounts for anywhere up to four percent of the total trash. That’s an extremely significant number, especially because e-waste is so heavy in lead. Given that four percent trash rate, e-waste becomes responsible for forty percent of the lead found in landfills. It accounts for whopping seventy percent of the other heavy and poisonous metals in landfills.

Luckily, most landfills are purposefully placed in locations where the soil and water contamination of the surrounding area can be contained and kept away from crops and water used by communities. Still, just the presence of that much hazardous waste on the surface of the ground can create problems.

This all seems to be a rather strong argument for the proper disposal of e-waste at locations meant to handle such strong and poisonous materials. Unfortunately, the sad fact remains that many so-called recycling centers in the United States and abroad are more of collection points than entities that have the intention of properly disposing of hazardous chemicals. E-waste is often sold to scrap brokers, who then ship the cargo to developing nations for deconstruction.

disc compDeconstruction entails the extremely chemically dangerous process of laborers smashing devices and harvesting them for their core components. Often the process by which the devices are opened causes toxic chemicals to be released in large amounts.

Luckily, many computer manufacturers are starting to make computers with fewer hazardous materials in them in the first place. However, this will not be enough to alleviate the problems caused by non-properly-disposed e-waste; major legislative change on a global level will have to happen.

location trackingTracking technology has become a must-have for travelers, commuters, and car-users in general. Where would we be without GPS? Probably still looking for what one drive-in movie theater  in Encino that everyone’s been talking about.

So how does location tracking work? The first distinction worth making is that between Geographic Information Systems (GIS) and Global Positioning Systems (GPS). GIS is more for large-scale location-tracking systems; these necessitate that geographic information be captured and stored. Accordingly, GIS can capture, store, analyze, and report geographic information.

GPS, on the other hands, operates by combining the information detected by 27 Earth-Orbiting satellites (24 of which operate act one time and three of which act as failsafes). A GPS receiver like the one in most mobile devices can detect how far it is from each of these satellites and deduce the device’s location accordingly, through a process called trilateration. Trilateration requires that a clear line of sight be reachable to four or more satellites at once.

There’s also Radio Frequency Identification (RFID), which is comprised of small microchips that can be attached to consumer goods, cattle, vehicles and other potentially moving objects to track their movements. RFID tags can only transmit data if prompted by a reader, which transmits radio waves that activate the tag, which then transmits information on a particular frequency.

Finally, there’s Wireless Local Area Network or WLAN tracking, which uses a network of devices connected through radio frequencies. As these devices pass over ready waves, they provide users with a network that ranges from 70 to 300 feet.

satellitesMany tracking of location-based service systems use one or a combination of all of these different types of technology. GPS is used by equipping all relevant vehicles with a GPS receiver; as a vehicle crosses a mass of land, the GPS satellites can track its position. GPS also allows for an operator to request positioning information at any time. Unfortunately, when it comes to trying to find something within a smaller space and especially indoors, GPS hits a wall.

For more local-area and indoor tracking, the best choices are the RFID and WLAN options. The smallest of the small tracking areas likely warrant an RFID while WLAN takes up the middle ground. For example, to track a child in an amusement parks, some parks are offering parents the option of outfitting the child with a wristband that holds the RFID tag. Then park staff can help a worried parent locate his or her child.

Another excellent use of location tracking is when an emergency occurs and someone calls 911. The government has developed technologies which are expected to enhance the ability of E-911 to locate callers, even if they’re not calling from a landline. This has been mandated by the Federal Communications Commission, so we likely can expect the service to improve rapidly within the next few years. It will begin with a few other phases, but eventually there will be a phase that forces carriers to place GPS receivers in phones in order to deliver more specific latitude and longitude location information to law enforcement in the event of an emergency call.
