Tri State Green PC
"Making The Tri State Greener, One PC At A Time."
Computer recycling refers to the practice of dismantling a computer and reusing its parts in other devices. With rapid advances in technology, computer models are rapidly becoming obsolete. Users simply dump them onto second-hand buyers. In many countries, old fashioned, obsolete and damaged computers are simply discarded in landfill sites as junk. However, accumulation of this electronic waste can be detrimental to the environment. Most electronic waste is sent to landfills or incinerated, which releases heavy metals such as lead, mercury, or cadmium into the soil, groundwater, and atmosphere, thus having a negative impact on the environment. Hence, it is wiser to use obsolete computers as secondary raw materials for other electronic devices.
Another advantage of reusing metals and plastics that are present in bulk quantities in computers or other electronics is that, it can reduce the costs of constructing new systems. Mining of metals is not only expensive, but also results in pollution of air, water bodies and soil. This can be drastically reduced if metals are recycled and reused repeatedly.
Sometimes, recycling may involve repairing and/or upgrading the discarded computer and reselling to an individual or organization that may have some use for it. This saves the cost, labour and time involved in pulling apart a computer and also is a cheap bargain for the buyer, who may not be in a position to invest in a new system. Sometime, the first user discards a system merely because he may have very specific needs- a faster RAM, a more spacious hard disk, different dimensions. However, in reality, the system under consideration may very well satisfy the needs (and fit the budget) of some other person. Thus, what is being discarded by one person may not necessarily be useless for everybody else.
Many times, the company/ dealer which sold the original computer may also agree to buy it back during an exchange offer. The company then takes apart the old system and recycles its components. Sometimes, the dilapidated system may be used to train mechanics and engineers.
Users should always try to exchange their systems, instead of merely dumping them and adding to environmental pollution. Old and apparently useless systems are very often more valuable than one can imagine.
At the same time, when one is looking to purchase a recycled system, one must be careful of fraudulent claims and must thoroughly assure the proper functioning of the system. Many times individuals may try to cheat customers by selling flawed systems at a very low price.
Despite its advantages, computer recycling also faces a lot of criticism. Among them, the most prominent ones are:
• Recycling is an expensive and labour-intensive practice
• The process of reclaiming metals and other components itself pollutes the environment
• The recycled system may have faulty parts if the quality assurance has not been done properly.
While western nations are rather serious about computer recycling, developing countries have still not warmed to the concept of computer recycling and are still disposing obsolete systems into landfills.
