Mark the statement that describes the eco- friendly disposal of municipal solid-waste

Options

A. It should be burnt to completion
B. It should be dumped in open waste land
C. It should be dumped in sanitary landfills
D. It should be sorted out into bio-degradable, non-bio-degradable and recyclable wastes and treated separately

Answer

**Step-by-Step Solution:**

1. **Understanding Eco-Friendly Disposal**: The first step is to define what eco-friendly disposal means. Eco-friendly disposal refers to methods that do not harm the environment and promote sustainability.

2. **Analyzing the Options**: The question provides four options for the disposal of municipal solid waste. We need to evaluate each option to determine which one aligns with eco-friendly practices.

3. **Evaluating Option A - Burning Waste**: The first option suggests burning waste to completion. While burning may reduce the volume of waste, it releases harmful fumes and pollutants into the air, contributing to air pollution and respiratory issues. Therefore, this option is not eco-friendly.

4. **Evaluating Option B - Dumping in Open Wasteland**: The second option involves dumping waste in open wasteland. This practice can lead to soil pollution and degradation, as harmful substances leach into the soil and can cause health issues for nearby populations. Thus, this option is also not eco-friendly.

5. **Evaluating Option C - Sanitary Landfills**: The third option mentions dumping waste in sanitary landfills. Although sanitary landfills are designed to manage waste, they can still pose risks, such as groundwater contamination and potential health hazards for nearby residents. Hence, this option does not fully meet eco-friendly criteria.

6. **Evaluating Option D - Separation of Waste**: The final option suggests separating biodegradable and non-biodegradable waste. This method allows for recycling and proper disposal of materials, reducing environmental impact. Biodegradable waste can be composted, while non-biodegradable waste can be recycled, making this option the most eco-friendly.

7. **Conclusion**: After evaluating all options, the most eco-friendly method of disposing of municipal solid waste is to separate biodegradable and non-biodegradable waste (Option D).

**Final Answer**: Option D - The biodegradable and non-biodegradable waste are separated.
