Which of the following is a common method for treating hazardous waste through chemical reactions?

  1. Incineration

  2. Solidification/Stabilization

  3. Neutralization

  4. Bioremediation


Correct Option: C
Explanation:

Neutralization is a chemical process that involves adding a base or acid to hazardous waste to adjust its pH and make it less corrosive or reactive.

What is the primary objective of solidification/stabilization in hazardous waste management?

  1. Reducing the volume of waste

  2. Destroying the hazardous components

  3. Preventing the release of contaminants

  4. Converting waste into energy


Correct Option: C
Explanation:

Solidification/stabilization aims to immobilize hazardous contaminants within a solid matrix, preventing their leaching or migration into the environment.

Which technology involves the use of microorganisms to break down and degrade hazardous contaminants?

  1. Incineration

  2. Vitrification

  3. Bioremediation

  4. Pyrolysis


Correct Option: C
Explanation:

Bioremediation utilizes the natural metabolic processes of microorganisms to transform hazardous contaminants into less harmful substances.

What is the purpose of vitrification in hazardous waste management?

  1. Reducing the volume of waste

  2. Recovering valuable materials

  3. Converting waste into energy

  4. Immobilizing hazardous contaminants


Correct Option: D
Explanation:

Vitrification involves melting hazardous waste at extremely high temperatures to form a stable, glass-like substance, immobilizing the contaminants and preventing their release.

Which of the following is a common method for reducing the volume of hazardous waste?

  1. Incineration

  2. Solidification/Stabilization

  3. Pyrolysis

  4. Landfilling


Correct Option: C
Explanation:

Pyrolysis is a thermal treatment process that involves heating hazardous waste in the absence of oxygen, resulting in the decomposition and volume reduction of the waste.

What is the primary objective of incineration in hazardous waste management?

  1. Reducing the volume of waste

  2. Destroying hazardous components

  3. Recovering valuable materials

  4. Immobilizing contaminants


Correct Option: B
Explanation:

Incineration involves burning hazardous waste at high temperatures to destroy organic contaminants and convert them into less harmful substances, such as carbon dioxide and water vapor.

Which of the following is a common method for recovering valuable materials from hazardous waste?

  1. Incineration

  2. Solidification/Stabilization

  3. Pyrolysis

  4. Solvent Extraction


Correct Option: D
Explanation:

Solvent extraction involves using a solvent to selectively dissolve and separate valuable materials from hazardous waste, allowing for their recovery and reuse.

What is the purpose of landfilling in hazardous waste management?

  1. Reducing the volume of waste

  2. Destroying hazardous components

  3. Recovering valuable materials

  4. Isolating waste from the environment


Correct Option: D
Explanation:

Landfilling involves disposing of hazardous waste in a specially designed and engineered facility, isolating it from the environment to prevent contamination of soil, water, and air.

Which of the following is a common method for treating hazardous waste through physical processes?

  1. Incineration

  2. Solidification/Stabilization

  3. Filtration

  4. Bioremediation


Correct Option: C
Explanation:

Filtration is a physical process that involves passing hazardous waste through a filter medium to remove suspended solids, impurities, or contaminants.

What is the primary objective of solidification/stabilization in hazardous waste management?

  1. Reducing the volume of waste

  2. Destroying the hazardous components

  3. Preventing the release of contaminants
