What is the primary goal of hazardous waste management?

  1. To minimize the generation of hazardous waste.

  2. To safely store and dispose of hazardous waste.

  3. To treat and recycle hazardous waste.

  4. To transport hazardous waste to designated facilities.


Correct Option: A
Explanation:

The primary goal of hazardous waste management is to reduce the amount of hazardous waste produced, thereby minimizing the risks associated with its handling, storage, and disposal.

Which technology is commonly used to separate hazardous waste from other materials?

  1. Incineration

  2. Landfilling

  3. Recycling

  4. Physical separation


Correct Option: D
Explanation:

Physical separation techniques, such as filtration, screening, and sedimentation, are commonly used to separate hazardous waste from other materials based on their physical properties.

What is the role of incineration in hazardous waste management?

  1. To reduce the volume of hazardous waste.

  2. To destroy hazardous waste completely.

  3. To separate hazardous waste from other materials.

  4. To recycle hazardous waste.


Correct Option: B
Explanation:

Incineration involves burning hazardous waste at high temperatures to destroy it completely, reducing its toxicity and volume.

Which technology is used to convert hazardous waste into less harmful substances?

  1. Incineration

  2. Landfilling

  3. Recycling

  4. Treatment


Correct Option: D
Explanation:

Treatment technologies, such as chemical, biological, and thermal processes, are used to convert hazardous waste into less harmful substances or to remove hazardous components from the waste.

What is the purpose of recycling hazardous waste?

  1. To reduce the amount of hazardous waste generated.

  2. To safely store and dispose of hazardous waste.

  3. To treat and convert hazardous waste into less harmful substances.

  4. To reuse hazardous waste in new products.


Correct Option: D
Explanation:

Recycling involves reusing hazardous waste in new products, thereby reducing the need for raw materials and minimizing the amount of hazardous waste disposed of.

Which technology is used to immobilize hazardous waste, making it less mobile and less likely to leach into the environment?

  1. Incineration

  2. Landfilling

  3. Solidification/stabilization

  4. Recycling


Correct Option: C
Explanation:

Solidification/stabilization involves mixing hazardous waste with binders or solidifying agents to create a solid or semi-solid form, reducing its mobility and potential for leaching.

What is the role of landfilling in hazardous waste management?

  1. To reduce the volume of hazardous waste.

  2. To destroy hazardous waste completely.

  3. To separate hazardous waste from other materials.

  4. To dispose of hazardous waste in a secure and contained manner.


Correct Option: D
Explanation:

Landfilling involves disposing of hazardous waste in specially designed and engineered landfills, which are designed to prevent the release of hazardous substances into the environment.

Which technology is used to monitor and control the release of hazardous waste into the environment?

  1. Incineration

  2. Landfilling

  3. Recycling

  4. Emission control systems


Correct Option: D
Explanation:

Emission control systems, such as scrubbers, filters, and electrostatic precipitators, are used to remove pollutants and hazardous substances from industrial emissions before they are released into the atmosphere.

What is the role of waste minimization in hazardous waste management?

  1. To reduce the amount of hazardous waste generated.

  2. To safely store and dispose of hazardous waste.

  3. To treat and convert hazardous waste into less harmful substances.

  4. To reuse hazardous waste in new products.


Correct Option: A
Explanation:

Waste minimization involves reducing the amount of hazardous waste produced at the source, which can be achieved through process modifications, material substitution, and improved waste management practices.

Which technology is used to separate hazardous waste from water or other liquids?

  1. Incineration

  2. Landfilling

  3. Recycling

  4. Liquid-liquid extraction


Correct Option: D
Explanation:

Liquid-liquid extraction involves separating hazardous substances from water or other liquids by using a solvent that selectively extracts the hazardous components.

What is the role of pollution prevention in hazardous waste management?

  1. To reduce the amount of hazardous waste generated.

  2. To safely store and dispose of hazardous waste.

  3. To treat and convert hazardous waste into less harmful substances.

  4. To reuse hazardous waste in new products.


Correct Option: A
Explanation:

Pollution prevention involves reducing or eliminating the generation of hazardous waste at the source, which can be achieved through process modifications, material substitution, and improved waste management practices.

Which technology is used to reduce the toxicity of hazardous waste?

  1. Incineration

  2. Landfilling

  3. Recycling

  4. Chemical treatment


Correct Option: D
Explanation:

Chemical treatment involves using chemical reactions to convert hazardous waste into less toxic or non-toxic substances.

What is the role of bioremediation in hazardous waste management?

  1. To reduce the amount of hazardous waste generated.

  2. To safely store and dispose of hazardous waste.

  3. To treat and convert hazardous waste into less harmful substances using biological processes.

  4. To reuse hazardous waste in new products.


Correct Option: C
Explanation:

Bioremediation involves using microorganisms or biological processes to break down and degrade hazardous waste into less harmful substances.

Which technology is used to monitor and control the movement of hazardous waste from its generation to its final disposal?

  1. Incineration

  2. Landfilling

  3. Recycling

  4. Waste tracking systems


Correct Option: D
Explanation:

Waste tracking systems involve using electronic or paper-based systems to track the movement of hazardous waste from its generation to its final disposal, ensuring proper handling and compliance with regulations.

What is the role of risk assessment in hazardous waste management?

  1. To reduce the amount of hazardous waste generated.

  2. To safely store and dispose of hazardous waste.

  3. To evaluate the potential risks associated with hazardous waste and develop appropriate management strategies.

  4. To reuse hazardous waste in new products.


Correct Option: C
Explanation:

Risk assessment involves evaluating the potential risks associated with hazardous waste, including its toxicity, mobility, and potential for exposure, to develop appropriate management strategies that minimize risks to human health and the environment.
