E Waste

Introduction

E waste or electronic wastes refers to the electronic goods that are dumped out or discarded. Each year around 50 million ton of e-wastes are produced. Depending upon their nature of reaction , there are possibilities for dangers depending upon the situation. Discarded computers, batteries and other electro chemical wastes may results in unwanted results. So its important to be aware of e wastes in addition to the other physical wastes. This article sounds the fact of e waste management and recycling.  

Basel Action Network (BAN) estimates that the 500 million computers in the world contain 2.87 billion kgs of plastics, 716.7 million kgs of lead and 286,700 kgs of mercury. The average 14-inch monitor uses a tube that contains an estimated 2.5 to 4 kgs of lead. The lead can percolates into the ground water from landfills thereby contaminating it. If the tube is crushed and burned, it emits toxic fumes into the atmosphere.

Disposing e wastes by burning leads to major problems and it accounts a major part in air pollution. The unwanted chemicals produce the fumes that get mixed up with the air and it destroys the nature of the air. Sequentially, it attacks human during respiration. So the recycling should be done to use them efficiently again.

Causes for E Waste

Ø  Manufacture Technology of a Computer

Ø  Invasion of Technology

Manufacturing Technology of a Computer

To manufacture a computer 240 kg of fossil fuel, 22kg of chemicals and 1500kg of water are needed. Once the computers are thrown out they may leads to many serious problems. Burning of fossil fuels leads to global warming and green house effect occurs. Thus the temperature of the atmosphere is getting increased, just think off if 240 kg of fossil fuel burnt per computer. Carbon dioxide content is made maximum with the burning of fossil fuels. Carbon dioxide is one of the greenhouse gases that enhances radioactive forcing and contributes to global warming

Invasion of Technology

Nowadays we can find computers in everyone’s home. It is estimated that there are over a billion personal computers in the world at present. The computers are becoming cheap so no one is bothering about its maintenance. In developed countries, computers have the life span of 2 years.

E waste management tips:

Ø  Don’t throw the waste cell phones, dumped systems into the land fills. Properly, deliver them to the organizations where recycling is carried out.

Ø  Get the electronic goods from the vendors who can take back for recycling.

Ø  Take care of life time of your hardware equipments and so that  e waste can be efficiently decreased

Ø  Big Industries may buy recyclers that can used for long time.

Ø  Support green engineering.

Ø  Citizens should turn their interests to use the recycled products

Waste minimization in industries involves adopting following methods for efficient waste management:

Ø  inventory management,

Ø  production-process modification,

Ø  volume reduction,

Ø  Recovery and reuse.

Conclusion

This article is made just to give the awareness of e wastes .Its the duty of every citizen to take care of their own electronic equipments and to recycle them. With the invasion of technologies, life is becoming comfortable but the nature is getting highly degraded .So Green Technologies should be welcomed for future world.
