E-Waste includes items like smartphones, TVs, refrigerators, laptops, and any device with a plug or battery that has been discarded.

2. 2. Which of the following best describes why e-waste is considered hazardous?

• A. It absorbs oxygen

• B. It contains toxic substances like lead, cadmium and mercury

• C. It decomposes too quickly

• D. It attracts pests in landfills

Answer explanation

3. Which environmental damage can result from e-waste in landfills?

• A. Enhanced plant growth

• B. Toxic chemicals leaching into soil and water

• C. Faster decomposition of paper

• D. Increased wildlife habitat

Answer explanation

When e-waste is improperly dumped in landfills, heavy metals and other toxins can leach out, polluting groundwater and surrounding ecosystems. This contaminates drinking water supplies and damages soil quality.

4. What is one major environmental risk of improperly managed e-waste?

• A. Sudden floods

• B. Noise pollution

• C. Wildlife migration

• D. Mercury and plastic pollution

5. Which harmful substance is most commonly released from mismanaged e-waste?

• D. Sulfur

6. What valuable materials are commonly found in e-waste?

• A. Gold and copper

• B. Wood and paper

• C. Clay and sand

• D. Silk and cotton

Answer explanation

E-waste contains valuable metals like gold, copper, platinum, and palladium, often found in circuit boards and wiring. These materials can be recovered through formal recycling processes, reducing the need for mining virgin ores and supporting the circular economy.

7. What is the environmental benefit of recycling e-waste instead of mining raw materials?

• A. Faster internet speed

• B. Less traffic congestion

• C. Reduced need to mine 900 billion kg of ore

• D. More phone models released annually

Answer explanation

Recycling metals from e-waste (also known as urban mining) avoids the environmental destruction caused by traditional mining, such as deforestation, water pollution, and greenhouse gas emissions.

8. What is the main cause of low e-waste recycling rates globally?

• A. Too many recycling plants

• B. Lack of consumer interest

• C. No valuable materials in electronics

• D. Weak legislation and poor enforcement

Answer explanation

Only about 22.3% of e-waste is formally collected and recycled globally. Many countries lack adequate laws or enforcement mechanisms to manage e-waste effectively. Informal recycling, lack of infrastructure, and low consumer awareness contribute to the challenge.
