Environmental Awareness and Impact practice questions

Donate the computers to a local school without wiping data.

Why wrong: This is incorrect because data security is a concern, and donation without proper recycling may still lead to eventual improper disposal.

Sell the computers to a scrap metal dealer.

Why wrong: This is incorrect because scrap dealers may not handle hazardous components safely, leading to environmental harm.

Have employees take the computers home for personal use.

Why wrong: This is incorrect because it merely transfers the disposal responsibility and may lead to improper end-of-life handling.

Use a degausser to erase the drive and then recycle it.

Why wrong: This is incorrect because degaussing damages the drive's electronics, making recycling more difficult and potentially leaving hazardous materials.

Drill holes through the platters and then dispose of the drive in e-waste.

Why wrong: This is incorrect because drilling may not fully destroy all data, and the drive still contains materials that need recycling.

Overwrite the drive with zeros multiple times and then donate it.

Why wrong: This is incorrect because the policy requires physical destruction; overwriting does not meet that requirement and donation may not be acceptable.

Use a vacuum cleaner with a standard bag to suck up the toner.

Why wrong: This is incorrect because standard vacuum bags may not trap fine toner particles, releasing them into the air and creating a health hazard.

Wipe the toner with a damp cloth using hot water.

Why wrong: This is incorrect because hot water can melt toner, causing it to bond with the carpet fibers and become permanent.

Sweep the toner into a dustpan and dispose of it in the trash.

Why wrong: This is incorrect because sweeping can aerosolize toner particles, leading to inhalation risks and spreading the mess further.

Sell the monitors to a local thrift store for reuse.

Why wrong: This is incorrect because while reuse extends life, eventual disposal still requires proper recycling; the thrift store may not ensure that.

Break the glass tubes to reduce volume and then place them in a dumpster.

Why wrong: This is incorrect because breaking CRTs releases lead dust and creates a hazardous waste spill, endangering workers and the environment.

Donate the monitors to a school art department for projects.

Why wrong: This is incorrect because donation does not guarantee eventual safe disposal; the school may later discard them improperly.

Throw the battery in the regular trash bin.

Why wrong: This is incorrect because lithium-ion batteries can leak toxic chemicals and cause fires in landfills; they must not be disposed of with regular trash.

Burn the battery in an open area to neutralize it.

Why wrong: This is incorrect because burning lithium-ion batteries releases toxic fumes and can cause explosions, posing serious health and safety risks.

Store the battery in a metal container until it stops holding a charge.

Why wrong: This is incorrect because storing a damaged battery does not address proper disposal; it still requires recycling to prevent environmental contamination.

Place the power supply in a standard trash bag and throw it in the dumpster.

Why wrong: This is incorrect because the leaking fluid may be toxic, and improper disposal can contaminate soil and water.

Clean the power supply with isopropyl alcohol and then recycle it normally.

Why wrong: This is incorrect because cleaning does not neutralize the hazardous materials, and normal recycling may not accept leaking components.

Disassemble the power supply to remove the leaking capacitor and then dispose of the rest.

Why wrong: This is incorrect because disassembly without proper training can expose the technician to toxic chemicals and electrical hazards.

LCD monitors

Why wrong: This is incorrect because LCD monitors are generally less hazardous, though they still benefit from recycling, they are not as critical as CRTs.

Keyboard and mouse

Why wrong: This is incorrect because keyboards and mice are typically non-hazardous and can be disposed of in regular e-waste streams without special precautions.

Ethernet cables

Why wrong: This is incorrect because Ethernet cables are copper-based and recyclable, but they do not contain hazardous materials that require separate handling.

Disable the screensaver and set the display to turn off after 30 minutes.

Why wrong: This is incorrect because while turning off the display saves some power, it does not put the entire system into a low-power state like sleep mode does.

Enable hibernation mode after 1 hour of inactivity.

Why wrong: This is incorrect because hibernation saves more power but has a longer wake time; sleep mode is more practical for short idle periods.

Set the power plan to 'High performance' to reduce power draw.

Why wrong: This is incorrect because 'High performance' increases power consumption, the opposite of the customer's goal.

Place them in the regular dumpster for pickup.

Why wrong: This is incorrect because lead-acid batteries are hazardous waste and illegal to dispose of in regular trash in most jurisdictions.

Burn them in an incinerator to recover energy.

Why wrong: This is incorrect because burning lead-acid batteries releases toxic lead fumes and sulfur dioxide, causing air pollution.

Store them indefinitely in a sealed container.

Why wrong: This is incorrect because indefinite storage risks leakage and does not comply with environmental regulations requiring proper disposal.

Power them on to see if they still function before disposal.

Why wrong: This is incorrect because powering on damaged equipment with leaking capacitors can cause short circuits, fires, or further leakage.

Use compressed air to blow out the leaked substance and then recycle the switches.

Why wrong: This is incorrect because blowing the substance can aerosolize it, leading to inhalation risks and spreading contamination.

Dispose of the switches in the regular office recycling bin.

Why wrong: This is incorrect because leaking capacitors make the switches hazardous waste, not regular recyclables.

Place them in the dumpster behind the office after hours.

Why wrong: Dumping e-waste in a regular dumpster is illegal and harmful to the environment due to toxic materials.

Break them down and put the plastic and metal in separate recycling bins.

Why wrong: CRTs contain leaded glass and require specialized processing; breaking them can release toxic dust.

Sell them to a scrap metal dealer.

Why wrong: Scrap metal dealers may not be equipped to handle hazardous CRT components safely.

Break them into small pieces and place them in a sealed bag in the trash.

Why wrong: Breaking fluorescent tubes releases mercury vapor, which is toxic, and disposal in trash is illegal.

Place them in the regular recycling bin for glass.

Why wrong: Regular glass recycling facilities cannot handle mercury contamination; this can contaminate the entire batch.

Burn them in an industrial incinerator.

Why wrong: Incinerating fluorescent tubes releases mercury into the atmosphere, causing environmental harm.

Throw them in the general office trash bin.

Why wrong: CDs are not biodegradable and contribute to landfill waste; they should be recycled.

Shred them and put the pieces in the recycling bin.

Why wrong: Shredding creates small pieces that may not be accepted by all recyclers and can contaminate other recyclables.

Burn them in an incinerator to generate energy.

Why wrong: Burning CDs releases toxic fumes and is not a recommended disposal method for small quantities.

Unplug the server from the UPS to simulate a power failure.

Why wrong: Unplugging the server risks data corruption and wastes the battery charge unnecessarily.

Disconnect the UPS from mains power and let the battery drain completely.

Why wrong: Full discharge cycles reduce battery lifespan and waste energy; they are only needed for calibration, not monthly testing.

Replace the UPS battery every month to avoid testing.

Why wrong: Replacing batteries monthly generates excessive hazardous waste and is not cost-effective or environmentally responsible.

Throw the switches in the company dumpster.

Why wrong: E-waste should never go in general trash; it contains hazardous materials and valuable resources.

Send the switches to a recycler even though they work.

Why wrong: Recycling is good, but reusing functional equipment is even better for the environment.

Keep the switches in storage indefinitely.

Why wrong: Storage delays disposal but does not solve the waste problem; it may lead to eventual disposal later.

Puncture the battery to release the pressure, then throw it in the trash.

Why wrong: Puncturing a lithium-ion battery can cause a fire or chemical leak; it is dangerous and not environmentally responsible.

Put it in a sealed plastic bag and put it in the regular recycling bin.

Why wrong: Regular recycling bins are not designed for hazardous batteries, and they can cause fires at recycling facilities.

Freeze the battery to stop the swelling, then dispose of it in the trash.

Why wrong: Freezing does not neutralize the hazard, and throwing it in the trash is still illegal and unsafe.

Perform a quick format of the drive before disposal.

Why wrong: A quick format only removes the file table; data can still be recovered with forensic tools.

Delete the files and empty the Recycle Bin.

Why wrong: Deleting files does not erase the data; it only marks the space as available, leaving data recoverable.

Replace the entire printer with a new Energy Star model.

Why wrong: Replacing the whole printer creates more electronic waste than necessary when only the fuser is faulty.

Continue using the printer until it fails completely.

Why wrong: Ignoring the smell and print quality could lead to a fire hazard and is not environmentally sound.

Disassemble the printer and dispose of all parts in the general trash.

Why wrong: Disposing of electronic components in general trash violates environmental regulations and increases landfill waste.

Set the computer to hibernate after 15 minutes of inactivity.

Why wrong: Hibernate saves more power but takes longer to wake, which can interrupt workflow if the user steps away briefly.

Disable all power-saving features to ensure maximum performance.

Why wrong: Disabling power saving wastes energy and increases the company's carbon footprint.

Set the monitor to turn off after 5 minutes but keep the computer on.

Why wrong: This saves some power but the computer still runs, wasting energy compared to sleep mode.

Replace the entire laptop with a new Energy Star model.

Why wrong: Replacing the whole laptop generates unnecessary e-waste when only the battery is faulty.

Remove the battery and run the laptop only on AC power.

Why wrong: This wastes the remaining useful life of the battery and does not address disposal of the old battery.

Continue using the laptop until the battery fails completely.

Why wrong: A hot, swollen battery is a fire risk; ignoring it is unsafe and not environmentally responsible.
