Understanding Biodegradable Waste
Biodegradable waste is material that can be decomposed naturally by living organisms, like bacteria and fungi, into simpler components such as water, carbon dioxide, and biomass.
Analyzing the Options
The task is to identify which item from the list is biodegradable:
- Glass bottle: Glass is manufactured from sand and silica, which are inorganic materials. It does not decompose naturally.
- Wooden pencil shavings: Wood comes from trees, which are organic matter. Wood decomposes over time, making it biodegradable.
- A crushed cold drink can: Cans are typically made of aluminum or steel. These metals do not biodegrade easily and can persist in the environment for a very long time.
- Polythene bag: Polythene (plastic) is a synthetic material derived from petroleum. It is non-biodegradable and contributes significantly to pollution.
Conclusion
Based on the analysis, only wooden pencil shavings are biodegradable.
