Which advanced waste treatment technology utilizes microorganisms to break down organic waste into biogas and digestate?

  1. Incineration

  2. Anaerobic Digestion

  3. Landfilling

  4. Pyrolysis


Correct Option: B
Explanation:

Anaerobic digestion is a biological process that converts organic waste into biogas and digestate in the absence of oxygen.

What is the primary objective of waste-to-energy (WtE) technologies?

  1. Reducing landfill space

  2. Generating renewable energy

  3. Producing compost

  4. Minimizing greenhouse gas emissions


Correct Option: B
Explanation:

WtE technologies aim to convert waste into usable energy sources, such as electricity or heat.

Which innovative waste management approach involves the conversion of organic waste into valuable biofuels?

  1. Plasma Gasification

  2. Hydrothermal Carbonization

  3. Mechanical Biological Treatment

  4. Bioconversion


Correct Option: D
Explanation:

Bioconversion processes utilize microorganisms or enzymes to transform organic waste into biofuels, such as biodiesel or ethanol.

What is the key advantage of mechanical biological treatment (MBT) in waste management?

  1. Eliminating the need for landfills

  2. Reducing the volume of waste for disposal

  3. Generating electricity from waste

  4. Producing high-quality compost


Correct Option: B
Explanation:

MBT involves mechanical and biological processes to reduce the volume and stabilize organic waste, making it suitable for further treatment or disposal.

Which waste management technology utilizes high temperatures to convert waste into a synthetic gas?

  1. Incineration

  2. Pyrolysis

  3. Gasification

  4. Plasma Gasification


Correct Option: C
Explanation:

Gasification involves the thermal conversion of waste into a synthetic gas mixture, which can be used as a fuel or for chemical synthesis.

What is the primary purpose of plasma gasification in waste management?

  1. Producing electricity from waste

  2. Generating synthetic gas

  3. Creating a vitrified slag

  4. Recovering valuable metals


Correct Option: C
Explanation:

Plasma gasification converts waste into a vitrified slag, which is a stable and inert material suitable for construction or landfill disposal.

Which waste management technology involves the thermal decomposition of waste in the absence of oxygen?

  1. Incineration

  2. Pyrolysis

  3. Gasification

  4. Plasma Gasification


Correct Option: B
Explanation:

Pyrolysis is a thermochemical process that breaks down organic waste into various products, including bio-oil, char, and gases, in the absence of oxygen.

What is the primary benefit of hydrothermal carbonization (HTC) in waste management?

  1. Reducing greenhouse gas emissions

  2. Producing biochar from organic waste

  3. Generating electricity from waste

  4. Recovering valuable metals


Correct Option: B
Explanation:

HTC is a thermochemical process that converts organic waste into a carbon-rich solid product called biochar, which has various applications, including soil amendment and carbon sequestration.

Which waste management technology utilizes microorganisms to convert organic waste into compost?

  1. Incineration

  2. Anaerobic Digestion
