8. How many tonnes of eWaste are expected by 2030?

Correct Answer: Correct answer is: (A) 82 million.

Exam Relevance: Environmental Science Exams, Sustainability Exams, Waste Management Exams

Difficulty: Moderate

Concept notes: The question pertains to the projected growth of electronic waste (eWaste) by 2030. According to recent studies and reports in the field of electronic waste management, the amount of eWaste is expected to increase significantly due to the rapid growth in technology and consumer electronics.

Common Mistakes: A common misunderstanding might be to confuse the current amount of eWaste with the projected amount for 2030. The current amount of eWaste is around 50 million tonnes, but the projection for 2030 is significantly higher.

Explanations: The correct answer is 82 million tonnes. This projection is based on trends in electronic consumption and disposal rates, which indicate a substantial increase in eWaste generation over the next decade. The growth is driven by factors such as the increasing use of electronic devices, shorter product lifecycles, and inadequate recycling and disposal practices.

Difficulty: Moderate

Concept notes: E-waste contains hazardous materials such as lead, mercury, and cadmium. When e-waste is dumped in landfills, these toxins can leach into the soil and groundwater, causing environmental pollution and health risks.

Common Mistakes: A common misunderstanding is that e-waste can be safely disposed of in landfills like regular waste, without considering the potential release of harmful substances.

Explanations: E-waste contains various toxic substances such as lead, mercury, cadmium, and brominated flame retardants. When e-waste is dumped in landfills, these toxins can leach into the soil and groundwater, leading to environmental contamination and posing risks to human health and ecosystems. Therefore, the correct answer is that dumping e-waste in landfills releases toxins.

Option Analysis:

Option A: This is incorrect because dumping e-waste in landfills does not save energy; it actually contributes to environmental degradation.
Option B: This is correct because e-waste contains hazardous materials that can leach into the environment when dumped in landfills.
Option C: This is incorrect because e-waste does not improve soil; it can contaminate it with toxic substances.
Option D: This is incorrect because dumping e-waste in landfills does not reduce costs; it incurs long-term environmental and health costs.

Mnemonic: Toxins in E-waste = TIE

10. What aspect of e-waste management does the text suggest needs to change?

Correct Answer: Correct answer is: (C) The country where recycling takes place.

Exam Relevance: Environmental Science Exams, Sustainability Exams, Waste Management Exams

Difficulty: Moderate

Concept notes: The text suggests that the location of e-waste recycling is a critical aspect of e-waste management that needs to change. This implies that the current practices of shipping e-waste to other countries for recycling may not be sustainable or ethical.

Common Mistakes: A common misunderstanding might be that the text is suggesting changes to the technology used in recycling or the pricing of electronic devices, rather than the location of recycling facilities.

Explanations: The text highlights the need to change the practice of sending e-waste to other countries for recycling. This suggests that the current global distribution of e-waste recycling facilities is problematic and needs to be addressed. The focus on the country where recycling takes place indicates that localizing or re-distributing recycling facilities could be a necessary change in e-waste management.

Option Analysis:

Option A: The text does not mention changing the location of recycling facilities within a country, but rather the country itself where recycling takes place.
Option B: The price of electronic devices is not discussed in the text as a factor needing change in e-waste management.
Option C: The text suggests that the country where recycling takes place needs to change, indicating a need to reconsider the global distribution of e-waste recycling.
Option D: The speed of technological advancement is not mentioned as a factor needing change in e-waste management.
