Exploring Biogas Production Methods

What is the primary raw material used in anaerobic digestion for biogas production?

• Metal scraps

• Plastic waste

• Glass bottles

• Organic materials such as food waste and manure

Name one method of biogas production that involves the use of landfills.

• Landfill gas recovery

• Thermal gasification

• Composting

• Anaerobic digestion

What role do microorganisms play in the biogas production process?

• Microorganisms produce energy through photosynthesis.

• Microorganisms decompose organic matter anaerobically to produce biogas.

• Microorganisms convert biogas into organic fertilizers.

• Microorganisms enhance soil quality by aerating it.

Describe the difference between wet and dry anaerobic digestion.

• Wet anaerobic digestion is used for composting solid waste.

• Wet anaerobic digestion uses a high moisture content slurry, while dry anaerobic digestion processes lower moisture content solid waste.

• Dry anaerobic digestion requires more water than wet anaerobic digestion.

• Wet anaerobic digestion is faster than dry anaerobic digestion.

What are the main byproducts of biogas production besides methane?

• Ammonia, carbon monoxide, and sulfur dioxide.

• Ethane, propane, and butane.

• Carbon dioxide, hydrogen sulfide, and residual organic matter.

• Oxygen, nitrogen, and water vapor.
