Waste Management and Incineration Quiz

Which of the following is NOT a byproduct of incineration?

• Fly ash

• Bottom ash

• Biochar

• Flue gases

What is the typical temperature range for modern incineration plants?

• 200–400°C

• 500–800°C

• 850–1100°C

• 1500–2000°C

Which air pollution control device is used to remove dioxins from incineration flue gas?

• Electrostatic precipitator

• Baghouse filter

• Activated carbon filter

• Cyclone separator

The waste-to-energy (WTE) process commonly associated with incineration is called:

• Pyrolysis

• Gasification

• Mass burn combustion

• Hydrothermal processing

Pyrolysis occurs in:

• The presence of excess oxygen

• Partial oxygen conditions

• Complete absence of oxygen

• High-pressure water environments

The key products of pyrolysis are:

• Biogas, tar, and fly ash

• Charcoal, bio-oil, and syngas

• Methane, carbon dioxide, and water

• Ash, soot, and sulphur dioxide

The fast pyrolysis process primarily produces:

• Syngas

• Biochar

• Bio-oil

• Hydrogen

The slow pyrolysis process is ideal for producing:

• Bio-oil

• Syngas

• Charcoal

• Steam

Anaerobic digestion requires:

• Oxygen-rich conditions

• High pressure

• Absence of oxygen

• High temperature

What type of waste is most suitable for anaerobic digestion?

• High-carbon plastic waste

• Organic food and agricultural waste

• Metal scrap

• Construction debris
