Biogas Production

📚 Key Concepts

🔹 Microbial Biogas Production

Anaerobic Digestion Process:

• Environment: Oxygen-free conditions
• Microorganisms: Anaerobic bacteria
• Raw Materials: Organic waste (plant/animal)
• Products: Biogas (methane + CO₂)

Chemical Process: Organic Matter → CH₄ + CO₂ + H₂O (Methane + Carbon dioxide + Water)

🔹 Biogas Composition

Typical Biogas Composition:

• Methane (CH₄): 50-70% (main fuel component)
• Carbon dioxide (CO₂): 30-40%
• Hydrogen sulfide (H₂S): 1-2%
• Other gases: Traces

🔹 Applications and Benefits

Uses of Biogas:

• Cooking: Clean burning fuel
• Heating: Warming homes and buildings
• Electricity generation: Power production
• Vehicle fuel: Compressed biogas (CBG)

Environmental Benefits:

• Waste reduction: Converts waste to energy
• Clean fuel: Reduces pollution
• Carbon neutral: No net CO₂ increase
• Renewable: Sustainable energy source
