There are many elements that make up a Laptop. These elements include plastics, metals, battery, and trace materials.
The plastic materials are used exterally in the laptop's body and internally in circuit boards. Some plastics have long chemical names such as, Polyvinychloride. However, most plastics are omposed of two key elements, which are carbon and hydrogen. Also, a few laptop plastics contain a additional elements such as, nitrogen, chlorine or sulfer.
Another element that makes up a laptop is metals. A lot of laptop bodies are made of the element called aluminum. The aluminum is used for its light weight, strength, and appearance. Another common element found in laptops is steel which is used for structural support. Steel is mostly iron, howeer it an also contain carbon and nickel. Also, copper is a substantial componet of laptops. Copper is used in wiring and to connect the electrial componets.
One of the largest componets in a laptop is a lithium-ion battery. The key element is lithium but other elements are also used for the electrlytes and componets. The most common lithium-ion batteries contain obatt, oxygen and carbon.
Lastly, trace materials are found in laptops. Elements that are commonly found in laptops in small quantities. Silion is used to manufacture mirohips. The optical components in laptop screen, can include indium, gallium and arsenic. Solder is made up of many different metals. For example, tin and bismuth. A few eletronic components have minute quantities of metals such as, gold or platinum.
Laptop Parts that can be Re-used
- Battery pack could be used again with the same model
- Power supply can also be used again for similar reasons
- The RAIM
- CMOS battery
- Optial drive
Materials that can be Hazardous
- Ciruit boards often contain dangerous metals including mercury and lead
- The interals of the laptop can contain Bromine and Polyvinyl Chloride which can affect health negatively
- Old CRTS
- LCD flat panels an pose a hazard
- Batteries and other consumables
Where do these elements come from?
Plastics: can be either found in a natural substane or can be man made. Also, plastics are made from the materials which are natural gas, oil , coal, minerals and plants
Metals: Most pure metals, like aluminuim, silver, and copper, come from the earth's crust
Example of blasting at the Red Dog mine in Northwest Alaska
The Recycling Process of a Laptop
The Laptop itself can last five years or more. However, the battery's life is a bit shorter. This is because, as the batteries age, they no longer have the ability to hold a charge. The lifespan of a laptop's battery depends on how it is used, but averages between 18 and 24 months.
Pros and Cons of a Laptop
Societal/Economic Pros : Mobility, light weight, size and portability allow us to use it in any location, security
Societal/Economic Cons: Vulnerable to damage, can be stolen easily, not easily upgraded with faster processors, cost more than desktops
Environmental Pros: While laptops have several problematic aspects, they are significantly greener than desktop computers
Environmental Cons: Use of earth metals in the making, potentially dangerous lead, have carbon footprint, the toxic materials within them then become part of landfills,
