What is biodegradable and compostable materials and what the difference between them?

Biodegradable and compostable materials may seem similar, but they have important differences. Here are some pointers to help you understand their unique characteristics:

1. Biodegradable materials:

• Biodegradable materials break down naturally over time, usually through the activity of microorganisms such as bacteria and fungi.
• These materials can be broken down into simpler compounds that can be safely absorbed by the environment without leaving behind any harmful residue.
• The rate of biodegradation depends on several factors like temperature, moisture, and the types of microorganisms present.

2. Compostable materials:

• Compostable materials can also be broken down by microorganisms, but they can be turned into nutrient-rich compost that can be used to fertilize the soil and promote plant growth.
• To create compost, a controlled environment with the right combination of moisture, temperature, and oxygen is necessary to encourage the growth of specific microorganisms that break down the material.
• Compostable materials are typically made from natural and organic sources, and they do not contain any synthetic or toxic materials.

3. Key differences:

• Biodegradable materials can break down naturally without leaving behind harmful residue, while compostable materials are broken down into compost that can be used to fertilize the soil.
• Compostable materials require a controlled environment to break down properly, while biodegradable materials can break down in any environment with the right conditions.
• Compostable materials are made from natural and organic sources, while biodegradable materials can be made from synthetic materials as long as they break down naturally over time.

In summary, biodegradable and compostable materials are both environmentally friendly options, but they have unique characteristics that make them suitable for different purposes.
