📖 1. Biodegradability processes and environmental conditions

📝 Essential Points

• Biodegradability is the process in which microorganisms convert organic matter into water, methane, and energy, culminating in mineralisation.
• Biodegradation requires specific environmental conditions: high temperature (about 50°C), UV light, moisture, and oxygen.
• Hydrolysis breaks bonds in plastic using water.
• Photodegradation occurs when UV light damages plastic.
• Microbial action involves bacteria consuming the material.
