Computer Hardware Recycling : a Challenging Task on the Face of Earth
E waste is one of the most serious issues that has engulfed the whole world. The obsolete computers, if not treated properly can become a major source of toxins and carcinogens. Rapid technology change, low initial cost and even planned obsolescence have resulted in a fast growing environmental concerns across the globe. Though many countries boast of technical solutions 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. E waste comprise 2% of America’s total trash and 70 percent of overall toxic waste. In the United States, an estimated 70% of heavy metals in landfills come from discarded electronics.
Recycling is one of the most effective ways to prevent the hazard of e waste. Many material used in the construction of hardware can be recovered and recycled. Reuse of tin, silicon, iron, aluminum, and a variety of plastics – all present in bulk in computers – is possible and can reduce the costs of constructing new systems. Electronic devices like including audio-visual components (televisions, VCRs, stereo equipment), mobile phones and other hand-held devices, and computer components, also contain valuable elements and substances that are suitable for reclamation. Powering and cooling computers is an increasing contributor to global warming and the power it consumes also contribute to a negative effect on the environment.
