Electronic waste encompasses more than carelessly discarded old batteries. The terminology describes digital devices and home appliances that all can potentially become part of the local garbage landfill, and includes microwaves and coffee-makers as well as expired computers. Although once limited to prosperous consumer nations, the problem is now worldwide. Processing Austin e-waste in a profitable and efficient manner is a goal shared by most Texas cities.
The primary driving force behind this explosion in consumer electronics is improved economics that expands buying ability while keeping prices down. Most types of these devices are constantly being improved, and there is no effort made to repair the old ones that fail. There have been many sensational news stories regarding the highly toxic substances they contain, but that issue is only one part of the picture.
Within discarded appliances are a host of precious metals. The old cathode ray computer displays are now phased out, but any device containing a printed circuit also holds a small but significant amount of platinum, palladium, gold, and silver. Substances with generally unfamiliar names such as gallium and indium play an important role in flat-screen technology and other innovations, and all have considerable after-market value.
It is impractical to do that extraction on a personal basis, but in large quantities this modern form of mining produces more pure metal than the original ores. Comparatively rare and costly metallic elements are a small fraction of the materials used to manufacture a new smartphone, which also contain significant amounts of copper and other more common metals. The accompanying plastics can also be partially recycled.
The key to successful recycling is profitability. It can be performed on smaller scales by individuals, but the most efficient operations employ numbers of people. Most centers begin by separating individual components manually, removing both processors and microchips from the original housing. The remaining fragments are then run through a specialized chipper that shreds them and makes more intense separation possible.
After having been re-mined, most of the remainder then sold back to manufacturing firms for the creation of new products. Manufacturers benefit because they do not have to extract as much basic raw material from the earth, and consumers also enjoy somewhat lower prices as a result. Disposing of personal electronic waste responsibly is only part of the overall scenario, which has a predictably darker side.
Each year the collective mound of electronic garbage increases dramatically along with renewed efforts to promote proper disposal, but good intentions cannot keep pace with current rates of production. The associated health hazards have been proven, including mercury and lead poisoning. Children exposed to those materials often have multiple developmental problems, and adults suffer brain and respiratory issues.
It is nearly impossible to determine the actual amount of used electronic parts that are discarded worldwide. The problem is an outgrowth of societal and economic realities, and solutions can be found that make use of similar motivation for financial gain. While reminding people about the health issues of re-use is important, the most workable long-term answer will be produced by developing the industries that process e-waste profitably.
