- The things which are broken down into their constituents by bacteria (decomposer) and fungus etc. are called biodegradable. Like vegetables, fruits, dead bodies of living beings etc.
IMPORTANT FACTS:
- But polythene and aluminum made by the use of chemicals by humans are not biodegradable materials.
- Biodegradable refers to everything that can be easily decomposed by natural agents.
- Natural agents include water, oxygen, ultraviolet rays of the sun, acid rain, microorganisms, etc.
- Non-biodegradable materials on the other hand never break down or decompose by environmental factors.
- Biodegradable materials include food waste such as vegetable and fruit peels, dead plants and animals, chicken, egg shells, paper materials, garden waste, etc.
- Non-biodegradable items include plastics, polystyrene, metals, plastic and aluminum cans, toxic chemicals, paints, tyres, etc.
- The biodegradable substances on breakdown are converted into simple organic matter and thus assimilated into the soil and thus become a part of the carbon cycle of the atmosphere. In contrast, non-biodegradable materials are resistant to environmental factors and never decompose and instead contribute to the majority of solid waste.
- Biodegradable substances can decompose in a few days or months while non-biodegradable objects can take thousands of years or never break down and remain in their original form.
