Which of the following is a major contributor to greenhouse gas emissions from waste management?

  1. Landfilling

  2. Recycling

  3. Composting

  4. Incineration


Correct Option: A
Explanation:

Landfilling organic waste leads to the generation of methane, a potent greenhouse gas, as it decomposes anaerobically.

What is the primary greenhouse gas emitted during the decomposition of organic waste in landfills?

  1. Carbon dioxide (CO2)

  2. Methane (CH4)

  3. Nitrous oxide (N2O)

  4. Hydrofluorocarbons (HFCs)


Correct Option: B
Explanation:

Methane is a potent greenhouse gas with a global warming potential 25 times higher than carbon dioxide.

Which waste management practice is most effective in reducing greenhouse gas emissions?

  1. Landfilling

  2. Recycling

  3. Composting

  4. Incineration


Correct Option: B
Explanation:

Recycling diverts waste from landfills, reducing methane emissions, and conserves natural resources and energy.

How does composting organic waste help mitigate greenhouse gas emissions?

  1. It reduces methane emissions from landfills.

  2. It captures carbon dioxide from the atmosphere.

  3. It produces renewable energy.

  4. It improves soil quality.


Correct Option: A
Explanation:

Composting organic waste diverts it from landfills, preventing the generation of methane during anaerobic decomposition.

What is the primary greenhouse gas emitted during the incineration of waste?

  1. Carbon dioxide (CO2)

  2. Methane (CH4)

  3. Nitrous oxide (N2O)

  4. Hydrofluorocarbons (HFCs)


Correct Option: A
Explanation:

Incineration of waste releases carbon dioxide, a greenhouse gas, into the atmosphere.

Which waste management practice is associated with the generation of hydrofluorocarbons (HFCs)?

  1. Landfilling

  2. Recycling

  3. Composting

  4. Refrigerant leakage


Correct Option: D
Explanation:

Hydrofluorocarbons (HFCs) are potent greenhouse gases primarily emitted through refrigerant leakage from refrigeration and air conditioning equipment.

What is the primary greenhouse gas emitted during the anaerobic digestion of organic waste?

  1. Carbon dioxide (CO2)

  2. Methane (CH4)

  3. Nitrous oxide (N2O)

  4. Hydrofluorocarbons (HFCs)


Correct Option: B
Explanation:

Anaerobic digestion of organic waste produces biogas, which primarily consists of methane, a potent greenhouse gas.

Which waste management practice is most effective in reducing nitrous oxide (N2O) emissions?

  1. Landfilling

  2. Recycling

  3. Composting

  4. Proper wastewater treatment


Correct Option: D
Explanation:

Proper wastewater treatment, particularly in industrial and agricultural settings, can reduce nitrous oxide emissions associated with nitrogen-rich wastewater.

How does waste reduction contribute to mitigating greenhouse gas emissions?

  1. It reduces the amount of waste sent to landfills.

  2. It conserves natural resources.

  3. It reduces energy consumption.

  4. All of the above


Correct Option: D
Explanation:

Waste reduction reduces the amount of waste sent to landfills, conserves natural resources, and reduces energy consumption, all of which contribute to mitigating greenhouse gas emissions.

Which of the following is a key strategy for reducing greenhouse gas emissions from waste management?

  1. Developing waste-to-energy technologies

  2. Promoting sustainable consumption and production

  3. Improving waste collection and disposal systems

  4. Encouraging recycling and composting


Correct Option: B
Explanation:

Promoting sustainable consumption and production reduces the generation of waste, thereby minimizing the need for waste management and associated greenhouse gas emissions.

What is the primary greenhouse gas emitted during the flaring of landfill gas?

  1. Carbon dioxide (CO2)

  2. Methane (CH4)

  3. Nitrous oxide (N2O)

  4. Hydrofluorocarbons (HFCs)


Correct Option: A
Explanation:

Flaring of landfill gas converts methane into carbon dioxide, a less potent greenhouse gas, reducing the overall greenhouse gas impact.

Which waste management practice is most effective in reducing greenhouse gas emissions from the transportation of waste?

  1. Using fuel-efficient vehicles

  2. Optimizing waste collection routes

  3. Reducing the frequency of waste collection

  4. All of the above


Correct Option: D
Explanation:

Using fuel-efficient vehicles, optimizing waste collection routes, and reducing the frequency of waste collection all contribute to reducing greenhouse gas emissions from waste transportation.

How does waste-to-energy technology contribute to mitigating greenhouse gas emissions?

  1. It converts waste into renewable energy.

  2. It reduces the amount of waste sent to landfills.

  3. It captures carbon dioxide from the atmosphere.

  4. All of the above


Correct Option: D
Explanation:

Waste-to-energy technology converts waste into renewable energy, reduces the amount of waste sent to landfills, and captures carbon dioxide from the atmosphere, all of which contribute to mitigating greenhouse gas emissions.

Which of the following is a key challenge in implementing effective waste management practices to mitigate greenhouse gas emissions?

  1. Lack of financial resources

  2. Insufficient infrastructure

  3. Public resistance to change

  4. All of the above


Correct Option: D
Explanation:

Lack of financial resources, insufficient infrastructure, and public resistance to change are all key challenges in implementing effective waste management practices to mitigate greenhouse gas emissions.

What is the role of international cooperation in addressing greenhouse gas emissions from waste management?

  1. Sharing best practices and technologies

  2. Providing financial and technical assistance

  3. Developing common standards and regulations

  4. All of the above


Correct Option: D
Explanation:

International cooperation plays a vital role in addressing greenhouse gas emissions from waste management by sharing best practices and technologies, providing financial and technical assistance, and developing common standards and regulations.
