Difference Between Biodegradable and Non-Biodegradable Substances

Difference Between Biodegradable and Non-Biodegradable

Biodegradability refers to the ability of a substance to be broken down naturally by microorganisms like bacteria and fungi. Some materials decompose easily, while others persist in the environment for a long time.

1. Definition

  • Biodegradable: Substances that can be decomposed naturally by microorganisms into harmless products like water, carbon dioxide, and organic matter.
  • Non-Biodegradable: Substances that cannot be easily broken down by natural processes and persist in the environment for a long time.

2. Decomposition Time

  • Biodegradable: Decomposes quickly, usually in days, weeks, or months.
  • Non-Biodegradable: Takes years or even centuries to decompose.

3. Impact on Environment

  • Biodegradable: Usually environmentally friendly and do not pollute.
  • Non-Biodegradable: Can cause pollution, clog drains, and harm wildlife.

4. Examples

  • Biodegradable: Food waste, paper, leaves, wood, cotton cloth.
  • Non-Biodegradable: Plastics, metals, glass, synthetic rubber, polythene bags.

5. Disposal

  • Biodegradable: Can be composted or recycled naturally.
  • Non-Biodegradable: Requires special disposal methods like recycling plants or landfills.

Key Point:

  • Biodegradable: Breaks down naturally and safely.
  • Non-Biodegradable: Persists in the environment and can cause pollution.
