According to an estimate around 3.5 billion people in the world use smartphones, and this number escalates every day. Smartphones and tablets are made from some valuable pieces of Earth’s crust. The pieces are extracted from mines all around the world. The extraction of nonrenewable elements such as gold, lithium, and cobalt can cause an environmental hazard.
One of the ways to avoid this situation is to promote the use of recycled phones and tablets. Several companies in Denmark buy and sell used devices. You can find more about such companies on Danskeanmeldelser.dk, they provide honest reviews about all the companies currently operating in Denmark. One of the best places to buy and sell used cell phones online is Phonetrade. They provide the best quality of recycled devices at a reasonable price. Listed below are some environmental impacts of smart devices.
- Destruction of Ecosystem
The most commonly used metals in smartphones are gold and tin. But mining of these metals is subject to ecological destruction. Gold in smartphones is used essentially to make wires and connectors. But gold mining is responsible for deforestation on a global level. Moreover, the wrenching of gold from the earth produces waste rich in cyanide and mercury, both extremely toxic substances that can pollute drinking water and fish, putting human health at stake.
Tin, on the other hand, is used for joining in electronics. To give touch screen functionality to smartphone and tablet screens Indium-tin oxide is applied as a slim, transparent, and conductive layer. Digging the seabed on a large scale to get the tin-rich sand has damaged the ecosystem leading to economic and social problems.
- Disastrous mine waste spills
In a smart device, Iron, aluminum, and copper are the most common metals by weight. Iron is used in mouthpieces and loudspeakers and stainless steel cases. Aluminum is used as a lightweight option for stainless steel and also in the assembling of the sharp glass used in screens of smart devices. Copper is used for electrical wiring.
Nonetheless, tremendous amounts of solid and liquid waste are generated when extracting these metals from the earth. Usually, mine tailings are stocked in large buildings that can be several square kilometers in area. Recent research has highlighted the danger of incorrect construction practices and slack security monitoring.
- Polluting the planet
What do you think makes a smartphone smart? The answer is the rare earth elements that are fundamental to smartphone design and function. Sharp and precise smartphone speakers, microphones, and vibrations are possible only because of small but impactful devices and magnets produced using rare earth elements.
Attractive colors of smartphone screens are also produced using these elements. The extraction of these elements involves the use of sulphuric and hydrofluoric acids which results in the production of extensive amounts of deeply toxic waste.
Conclusion
Everyone likes to use new smartphones and tablets these days. But the cost that our environment pays for us to use smart devices can be immense and is presumably way greater than we think. To make our environment safer and to keep the planet earth inhabitable, we must begin using recycled smart devices.
