Types of E-Waste: What You Need to Know


Electronic waste, or e-waste, is a term that covers any discarded electrical or electronic device that has reached the end of its useful life. E-waste can include anything from old cell phones and laptops to refrigerators and TVs.

According to the United Nations, the world generated 53.6 million metric tons of e-waste in 2019, and only 17.4% of it was formally collected and recycled.

Key Takeaways
E-waste is any discarded electrical or electronic device that has reached the end of its useful life.
E-waste can contain hazardous components, such as lead, mercury, cadmium, beryllium, brominated flame retardants, and polychlorinated biphenyls, that can harm human health and the environment if not handled properly.
E-waste can also contain valuable materials, such as metals, plastics, glass, and ceramics.
Some types of devices, such as large household appliances, lamps and luminaires, toys and leisure equipment, and medical devices and equipment, are less likely to be recycled.
Alternatives to discarding e-waste include repairing, reusing, and recycling.
Rugged Books offers high-quality refurbished laptops certified by R2, a trade-in program, and free shipping labels for recycling old laptops.

E-waste is not only a huge environmental problem, but also a waste of valuable resources. Many electronic devices contain precious metals, such as gold, silver, platinum, and palladium, as well as other useful materials, such as copper, iron, aluminum, and plastic. These materials can be recovered and reused if e-waste is properly recycled. However, if e-waste is dumped in landfills or incinerated, these materials are lost forever and can cause serious harm to human health and the environment.

In this article, we will explore the different types of e-waste, their hazardous components, their common materials, and their recycling rates. We will also discuss some alternatives to discarding e-waste and how you can contribute to a more sustainable future.

Types of Electronics

There are many ways to classify e-waste, but one common method is based on the categories used by the United States Environmental Protection Agency (EPA). The EPA divides e-waste into 10 types of electronics:

  • Large household appliances, such as refrigerators, freezers, washing machines, dryers, dishwashers, ovens, and microwaves.
  • Small household appliances, such as vacuum cleaners, toasters, coffee makers, hair dryers, electric shavers, and fans.
  • Information technology (IT) equipment, such as computers, laptops, tablets, monitors, keyboards, mice, printers, scanners, routers, and servers.
  • Consumer electronics, such as TVs, DVD players, game consoles, cameras, camcorders, speakers, headphones, and musical instruments.
  • Lamps and luminaires, such as fluorescent tubes, LED bulbs, desk lamps, and chandeliers.
  • Toys and leisure equipment, such as electric toys, video games, sports equipment with electronic components (e.g., treadmills), and hobby devices (e.g., sewing machines).
  • Tools and machinery, such as drills, saws, soldering irons, welding machines, lawnmowers, and generators.
  • Medical devices and equipment, such as x-ray machines, ultrasound machines, blood pressure monitors, and thermometers.
  • Monitoring and control instruments, such as thermostats, smoke detectors, fire alarms, and security cameras.
  • Automatic dispensers, such as ATMs, vending machines, and ticket machines.

These categories are not mutually exclusive, and some devices may belong to more than one category. For example, a smartphone can be considered both an IT equipment and a consumer electronic.

Hazardous Components

One of the main challenges of e-waste management is that many electronic devices contain hazardous components that can pose serious risks to human health and the environment if not handled properly. Some of the most common hazardous components found in e-waste are:

Lead is a toxic metal that can damage the nervous system, the brain, the kidneys, and the blood. Lead is often used in soldering, circuit boards, glass panels of CRT monitors and TVs, and batteries.

Mercury is a highly poisonous element that can affect the brain, the nervous system, the kidneys, and the reproductive system. Mercury is often used in fluorescent lamps that provide backlighting in LCD monitors and TVs, in some batteries, and in some switches and relays.

Cadmium is a carcinogenic metal that can cause lung cancer and kidney damage. Cadmium is often used in rechargeable batteries (e.g., Ni-Cd), in circuit boards, in light-sensitive resistors, and in some plastics.

Beryllium is a metal that can cause lung diseases and skin allergies. Beryllium is often used in power supply boxes that contain silicon-controlled rectifiers, in x-ray tubes, and in some connectors and springs.

Brominated flame retardants (BFRs)
BFRs are chemicals that are added to plastics to make them more resistant to fire. However, BFRs can also be harmful to the endocrine system, the thyroid gland, and the liver. BFRs are often used in plastic casings of electronic devices, in circuit boards, in cables, and in some textiles.

Polychlorinated biphenyls (PCBs)
PCBs are synthetic organic compounds that are used as coolants and insulators in electrical equipment. PCBs are persistent organic pollutants (POPs) that can accumulate in the environment and in living organisms. PCBs can cause cancer and affect the immune system, the reproductive system, and the nervous system. PCBs are often used in transformers, capacitors, and older fluorescent lamps.

These hazardous components can leach into the soil and groundwater if e-waste is dumped in landfills or can release toxic fumes and dioxins if e-waste is burned. Therefore, it is essential to dispose of e-waste in a safe and responsible manner, following the appropriate regulations and standards.

Common Materials Found in E-Waste

Besides hazardous components, e-waste also contains many common materials that can be recovered and reused if e-waste is properly recycled. Some of the most common materials found in e-waste are:

Metals are the most valuable and abundant materials in e-waste. They include ferrous metals (e.g., iron and steel), non-ferrous metals (e.g., aluminum and copper), and precious metals (e.g., gold, silver, platinum, and palladium). Metals can be used to make new electronic devices or other products, such as jewelry, coins, or medals.

Plastics are the most widely used materials in electronic devices, as they are lightweight, durable, and versatile. However, plastics are also difficult to recycle, as they come in many different types and grades, and often contain additives and contaminants. Plastics can be used to make new electronic devices or other products, such as furniture, toys, or packaging.

Glass is mainly used in monitors and TVs, especially those with CRT technology. Glass can also contain lead or other metals that need to be separated before recycling. Glass can be used to make new monitors or TVs or other products, such as bottles, jars, or windows.

Electronics, Glass and Plastics

These common materials can be recycled using various methods, such as shredding, sorting, smelting, refining, extruding, molding, or melting. Recycling these materials can save energy, reduce greenhouse gas emissions, conserve natural resources, and create new economic opportunities.

Alternatives to Discarding E-Waste

Discarding e-waste is not only wasteful but also harmful to the environment and human health. Therefore, it is important to consider some alternatives to discarding e-waste whenever possible. Some of the alternatives to discarding e-waste are:

Repairing is one of the best ways to extend the lifespan of electronic devices and avoid generating e-waste. Repairing can involve fixing minor issues, such as replacing a broken screen, a faulty battery, or a worn-out cable, or upgrading some components, such as adding more memory, a faster processor, or a larger hard drive. Repairing can also save money, as it is usually cheaper than buying a new device. 

Reusing is another way to prolong the usefulness of electronic devices and prevent creating e-waste. Reusing can involve donating or selling functional devices to someone who needs them, such as a family member, a friend, a charity, or a second-hand shop.  Reusing can also benefit society, as it can provide access to technology for people who cannot afford new devices. However, reusing may not be suitable for some devices, especially those that are obsolete or incompatible with current standards or software.

Recycling is the last resort when electronic devices cannot be repaired or reused. Recycling is the process of recovering and reprocessing the materials from e-waste and turning them into new products. Recycling can reduce the environmental impact of e-waste by saving energy, reducing greenhouse gas emissions, conserving natural resources, and preventing pollution.
