  1. Waste-to-Energy

  2. Energy-to-Waste

  3. Waste-to-Fuel

  4. Fuel-to-Waste


Correct Option: A
Explanation:

Waste-to-Energy is the process of converting waste materials into usable energy, such as electricity, heat, or fuel.

Which type of waste is commonly used as feedstock for Waste-to-Energy technologies?

  1. Municipal Solid Waste

  2. Industrial Waste

  3. Agricultural Waste

  4. All of the above


Correct Option: D
Explanation:

Waste-to-Energy technologies can utilize various types of waste as feedstock, including municipal solid waste, industrial waste, and agricultural waste.

What is the primary technology used for converting waste into electricity?

  1. Incineration

  2. Gasification

  3. Pyrolysis

  4. Anaerobic Digestion


Correct Option: A
Explanation:

Incineration is the primary technology used for converting waste into electricity. It involves burning the waste at high temperatures to generate steam, which drives a turbine to produce electricity.

Which technology converts waste into a combustible gas?

  1. Incineration

  2. Gasification

  3. Pyrolysis

  4. Anaerobic Digestion


Correct Option: B
Explanation:

Gasification is a technology that converts waste into a combustible gas called syngas. This gas can be used to generate electricity, heat, or fuel.

What is the process of chemically decomposing waste materials in the absence of oxygen called?

  1. Incineration

  2. Gasification

  3. Pyrolysis

  4. Anaerobic Digestion


Correct Option: C
Explanation:

Pyrolysis is the process of chemically decomposing waste materials in the absence of oxygen. It produces a mixture of gases, liquids, and solids that can be used for various purposes.

Which technology converts organic waste into biogas?

  1. Incineration

  2. Gasification

  3. Pyrolysis

  4. Anaerobic Digestion


Correct Option: D
Explanation:

Anaerobic Digestion is a technology that converts organic waste into biogas, a mixture of methane and carbon dioxide. This biogas can be used to generate electricity, heat, or fuel.

What is the primary environmental benefit of Waste-to-Energy technologies?

  1. Reducing greenhouse gas emissions

  2. Diverting waste from landfills

Correct Option: D
Explanation:

Waste-to-Energy technologies face several challenges, including high capital costs, complex operation and maintenance, and public acceptance and perception.

Which technology is commonly used for converting waste into solid fuels?

  1. Incineration

  2. Gasification

  3. Pyrolysis

  4. Torrefaction


Correct Option: D
Explanation:

Torrefaction is a technology that converts waste into solid fuels through a process involving heating the waste in the absence of oxygen.

What is the primary advantage of Waste-to-Energy technologies over traditional waste disposal methods?

  1. Reduced greenhouse gas emissions

  2. Diverted waste from landfills

  3. Generation of renewable energy

  4. All of the above


Correct Option: D
Explanation:

Waste-to-Energy technologies offer several advantages over traditional waste disposal methods, including reduced greenhouse gas emissions, diverted waste from landfills, and generation of renewable energy.
