Question

Identify the treatment technology/technologies NOT recommended for highly biodegradable organic solid wastes.
 

• A. Biohydrogenation
• B. Anaerobic digestion
• C. Composting
• D. Open dumping

Hint:

Avoid open dumping — it causes pollution and health hazards. Use biological treatments like composting or digestion for organic waste.

Answer 1

The Correct Option is D

Biodegradable organic waste should be managed using sustainable and environment-friendly technologies:

- Biohydrogenation (A): Suitable for converting organic material into bio-hydrogen, an emerging green fuel.

- Anaerobic digestion (B): Widely used method for treating organic waste in the absence of oxygen, producing biogas as a useful by-product.

- Composting (C): An aerobic process of biodegradation that converts organic matter into useful compost.

- Open dumping (D): Incorrect practice. It leads to uncontrolled decomposition, release of methane, foul smell, contamination of soil and groundwater, and spread of disease vectors.
Therefore, open dumping is not recommended for any kind of waste, especially not for highly biodegradable organic matter.
