E-Waste Problems and Environmental Impacts
E-Waste Problems Introduction
When the service life of consumable items in these sectors expires, device and hardware owners must then face the dilemma of how to dispose of electronics: Sell? Recycle? Or just throw them away?
While the throw-away and recycling options for electronic disposal often have the advantage in terms of speed and convenience for the owner, the types of materials they’re discarding or recycling can throw up the issue of e-waste and how best to manage and dispose of it.
What is E-waste?
E-waste is the term used to describe any discarded electronic device or a product that contains electronic components. That basically includes anything that uses electricity, either from a power outlet or a battery.
Why has E-waste Become so much of a Problem?
As the use of technology has grown worldwide, the need to dispose of obsolete and surplus equipment has also grown exponentially. Technology soon becomes obsolete, at home as well as in the office. Think about:
- Video tape recorders
- Walkman tape players
- Electronic calculators
- CRT monitors
- Dot matrix printers
- The number of batteries that power these things
In the past these were usually dumped with the rest of the garbage. But the environmental impact of e waste is now recognized as a massive ecological problem by many governments.
E waste problems have been made worse by the short lifetime of today’s electronic products, which can be 2 years or even less for things like:
- Digital watches
- Mobile phones
- Smoke alarms
- Children’s toys
How Serious are E-Waste Problems?
The environmental hazards of e waste should not be underestimated. Every bit of e waste, no matter how small, contains substances that cause pollution. Dumping e waste without attempting to recycle the contents also depletes the earth’s resources.
The scale of problems with e waste is massive: In 2021 the global volume of e-waste generated was 48 million tons which is 6.8kg for every person on the planet. By 2030 this is expected to be 67 million tons, double what it was in 2014.
What’s in E-waste?
E-waste contains a wide variety of materials that affect the environmental impact of e waste including:
- Other toxins
These are used in electronic components including circuit boards, power supplies, heat sinks, wires, screens, hard drives and more.
The hazards to the environment from e waste components depend on the type of product and its age:
Lead: Damages brain function, particularly in children
Americium: Can induce cancer
Mercury: Causes memory loss, muscle weakness, and reduced fertility
Cadmium: Severe lung damage if breathed in
Sulfur: Damages the liver, heart, kidneys, and eyes.
Chromium: A known cause of cancer
Formal and Informal E Waste Recycling
E-waste recycling can be done formally or informally. Both approaches attempt to solve e waste problems, but informal recycling increases the environmental impact of e waste and the environmental hazards of e waste.
Here we will explore the differences and the environmental impact of the two e waste recycling methods. These can help answer the question ‘e waste why is it a problem?’
Formal e waste recycling
Formal recycling tries to minimize the environmental hazards of e waste by using responsible and ethical approaches. It includes:
- Careful disassembly
- Separation into raw material types
- Shredding ready for re-use
Formal e waste recycling is more expensive and takes more time than informal approaches. Companies that use formal e waste recycling follow strict health and safety rules and pollution free techniques to protect their employees and the environment.
Informal E waste Recycling
Because of the high costs and government regulations of formal recycling, many companies choose to export their e-waste to developing countries where recycling is cheaper.
Poorly paid and exploited men, women, and children use methods to recover valuable materials that release harmful pollutants and toxins into the environment:
- Incinerating to destroy unwanted materials
- Using toxic mercury and acids to recover gold
The workers and people living nearby are often harmed by these processes.
Negative effects of e-waste on the environment
The environmental impact of computer disposal and other e-waste can have negative effects on
E-Waste Problems: Negative effects of e-waste on air
Careless dismantling, shredding and incineration releases harmful dust and toxins into the air, polluting it and causing damage to the respiratory system. The fine particles can travel thousands of miles, so the environmental hazards of e waste can cause harm not just in the country where the recycling is done.
Negative effects of e-waste on soil
This environmental impact of e waste is long lasting. Putting e-waste in the garbage will release toxins into the soil as it degrades. Informal recycling does the same. These toxins can:
- Deform plants
- Reduce crop yields
- Be absorbed by the crops which are then eaten by livestock or humans
Soil can also be contaminated by large particles produced by burning e-waste. The level of contamination depends on factors including soil type, temperature, and PH levels. These pollutants can stay in the soil for a long time, and harm microorganisms in soil that help to provide fertility.
E-Waste Problems: Negative effects of e-waste on water
Rain flushes toxic heavy metals out of contaminated soil into water systems. The polluted water then harms plants, animals, and humans. This can be many miles away from the original contamination source and includes the oceans.
The pollutants make water more acidic and toxic. E waste problems with water:
- Kill marine and freshwater plants and fish
- Harm biodiversity
- Destroy ecosystems
Negative effects of e-waste on humans
Electronic waste contains a cocktail of toxic components that are dangerous to human health. These poisons can harm the:
- Nervous system
- Reproductive system
They can also cause deformities in unborn babies.
What to Look for in an E-Waste Disposal Service
So how can we solve the problem of e waste? The best way is to use a multi solution approach that changes how people think and behave.
E-waste Problems In Summary
E waste has been poisoning our fragile planet for years, ever since electricity was first invented. The consequences of failing to tackle e waste problems pose serious threats to public health and the future of humankind. You can do your part to help reduce the impact of e waste.
