Computer recycling

  Computer recycling refers to any process by which a computer (or other electronic device) is disposed of in a safe manner that prevents it from going to waste or becoming an environmental health hazard. This can include finding another use for the system (i. e. donated to charity), or having the system dismantled in a manner that allows for the safe extraction of the constituent materials for reuse in other products.

Reasons to recycle

Obsolete computers are a valuable source for secondary raw materials, if treated properly, however if not treated properly they are a major source of toxins and carcinogens. Rapid technology change, low initial cost and even planned obsolescence have resulted in a fast growing problem around the globe. Technical solutions are available but in most cases a legal framework, a collection system, logistics and other services need to be implemented before a technical solution can be applied. Electronic waste represents 2 percent of America's trash in landfills, but it equals 70 percent of overall toxic waste.^[1]

Many materials used in the construction of computer hardware can be recovered in the recycling process for use in future production. Reuse of tin, silicon, iron, aluminum, and a variety of plastics – all present in bulk in computers – can reduce the costs of constructing new systems. In addition, components frequently contain copper, gold, and other materials valuable enough to reclaim in their own right.

Regulations

In February 2003, the European Community signed into law the Waste Electrical and Electronic Equipment Directive 2002/96/EC^[2] (WEEE Directive). The directive imposes the responsibility for the disposal of waste electrical and electronic equipment (WEEE) on the manufacturers of such equipment. Those companies should establish an infrastructure for collecting WEEE, in such a way that "Users of electrical and electronic equipment from private households should have the possibility of returning WEEE at least free of charge". Also, the companies are compelled to use the collected waste in an ecological-friendly manner, either by ecological disposal or by reuse/refurbishment of the collected WEEE.

The Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment 2002/95/EC^[3] (commonly referred to as the Restriction of Hazardous Substances Directive or RoHS) was adopted in February 2003 by the European Union. The RoHS directive took effect on 1 July 2006, and is required to be enforced and become law in each member state. This directive restricts the use of six hazardous materials in the manufacture of various types of electronic and electrical equipment.

Consumer recycling

Most major computer manufacturers offer some form of recycling, often as a free replacement service when purchasing a new PC. At the user's request they may mail in their old computer, or arrange for pickup from the manufacturer. There are also a variety of donation options, including charities which may offer tax benefits. The United States Environmental Protection Agency maintains a list of electronic recycling and donation options for consumers in the US.

Corporate recycling

Businesses seeking a cost-effective way to responsibly recycle large amounts of computer equipment face a more complicated process. They also have the option of contacting the manufacturers and arranging recycling options. However, in cases where the computer equipment comes from a wide variety of manufacturers, it may be more efficient to hire a third-party contractor to handle the recycling arrangements. There exist companies that specialize in corporate computer disposal services both offer disposal and recycling services in compliance with local laws and regulations. Such companies frequently also offer secure data elimination services.

Concerns

One of the major concerns about computer recycling programs is export of waste to countries with lower environmental standards. Companies may find it cost effective in the short-term to sell outdated computers to less developed countries with lax regulations. The Basel Convention is an international treaty intended to restrict this sort of practice, but it has proven difficult to enforce and the United States has not yet ratified the agreement. Because the US has no domestic laws forbidding the export of toxic waste, the Basel Action Network estimates that about 80% of the e-waste directed to recycling in the US does not get recycled there at all but is put on container ships and sent to countries such as China.^[4] Due to lower environmental standards and working conditions in China, India, Kenya, and elsewhere, electronic waste is being sent to these countries for processing – in most cases illegally. Guiyu in Shantou region of China, and Delhi and Bangalore in India, all have electronic waste processing areas.^[5] Uncontrolled burning, disassembly, and disposal are causing environmental and health problems, including occupational safety and health effects among those directly involved, due to the methods of processing the waste.
