Life Cycle of Cell Phones

Packaging and Distribution

Product Use

Disposal

Typically made from cardboard with an insert being made from recycled polystyrene. The boxes typically get a gloss finish. The boxes are square so they can be stacked on shelves easily. The box shapes are efficient.

Typically, people just throw away their phones, causing environmental issues. Phones can be properly disposed at collection centers, where companies will either reuse the phone, or just certain parts.

Product Manufacturing

Mobile phones today allows users to send and receive text messages, emails, photo and videos as well as accessing the internet.

Reusing

Fiberglass is used to make the circuit board, which is plated in gold.

Circuit boards are connected with circuits and wires, secured with protective glues and coatings.

Batteries are made of two types of electrodes. Electrolytes touch electrodes. When electricity touches, the chemicals react.

Although one might get a new phone, the old phone can still be used for:

  • Pictures
  • Music
  • Overall Storage

Some phone companies allow users to sell back their phones while in good conditions to distribute properly.

Environmental Impacts

Material Processing

Metals

Plastics

Current Events

Metals, (copper), ground, heated, and treated with chemicals and electricity to make cable, circuit boards and batteries.

Crude oil is combined with natural gas and chemicals in a processing plant to make plastic.

Material Extraction

Reducing Environmental Impacts

  • Policy Change
  • Increase the amounts of recycling with phone parts
  • Reuse phones for other purposes
  • Use phones until they are completely unusable
  • Design phones to be durable

Circuit Boards

Batteries

Liquid Crystal Display (LCD)

Made of:

Plastics, Silicon, Copper, Gold, Nickel, Beryllium, &Tantalum

Made of:

nickel, cobalt, zinc, cadmium, copper, lithium, metallic oxide and other carbon-based materials.

Made of:

Plastic, glass, liquid crystalline and mercury (non-renewable resources)

Extraction of crude oils.

Metals are mined out of the Earth.

Potentially dangerous if they are buried in a landfill.

Mercury is a heavy metal which can be harmful to the environment

Most cellphones now are made out of lithium-ion batteries, which are non-toxic.

The earth's crust is drilled in order to get metals in the earth
