Question

Activity-5 Biodegradable and Non-biodegradable Materials Find out biodegradable and non-biodegradable material used in day to day life. Procedure:1. Find out different types of waste materials.2. Find out their physical and chemical properties (Reaction towards water and combustion.3 Think about how you can reduce, reuse, recycle and recover (4R's principle) on biodegradable materials and write about

Answer 1

Biodegradable materials can be decomposed by microorganisms in the environment and non-biodegradable materials are decomposed by soil bacteria converting them into organic wastes.

Biodegradables are: human wastes, animal wastes, plant products, food wastes, bodies of dead beings.

Non-biodegradables are: Plastics, glass, metallic components, medical wastes, chemical wastes. Biodegradables can be recycled through environment exposures while non-biodegradables require physical and chemical process for recycling.

Answer 2

Answer:

• Biodegradable waste:

1. A biodegradable substance or material is one that may quickly breakdown by bacteria or any other natural organisms without contributing to pollution.
2. Wastes that are easily broken down by abiotic elements including temperature, UV, oxygen, and other natural elements such as bacteria, fungi, and other microbes are known as biodegradable wastes.
3. Some examples of these wastes include food wastes, kitchen wastes, and other organic wastes.
4. Together with other abiotic components, microorganisms decompose complicated materials into simple organic matter that eventually suspends and dissipates into the earth.
5. The entire procedure, which might go quickly or slowly, is natural. Therefore, there are very few hazards and environmental problems associated with biodegradable garbage.

• Non-biodegradable waste:

1. It is possible to define a non-biodegradable material as a kind of material that is a source of pollution and cannot be degraded by natural organisms.
2. Non-biodegradable wastes, in contrast to biodegradable wastes, are more difficult to manage.
3. Wastes that cannot be broken down or degraded by natural processes are referred to as non-biodegradable wastes.
4. They last on the planet for tens of thousands of years without deteriorating or decomposing.
5. As a result, the threat they pose is likewise more serious.
6. A plastic is a good illustration because it is typically utilized in practically every field.
7. Better quality plastics are being employed to offer these plastics a long-lasting result.
8. They became stronger even after use and more temperature resistant as a result.
