Arrange the following solid waste types in increasing order of their moisture content:
A. Trash (100% trash) B. Rubbish [Rubbish 80% + Garbage 20% by weight] C. Refuse [Rubbish 50% + Garbage 50% by weight] D. Animal solids and organic waste [100% Animal and human tissue] E. Garbage [Rubbish 35% + Garbage 65% by weight]
Choose the correct answer:

Correct option is C

The correct order of the solid waste types in increasing order of moisture content is:
1. A. Trash (Lowest moisture)
2. B. Rubbish
3. C. Refuse
4. E. Garbage
5. D. Animal solids and organic waste (Highest moisture)
Therefore, the correct answer is Option (c): A, B, C, E, D.
Explanation:
1. A. Trash:
· Contains mostly dry, non-organic materials such as paper, cardboard, and plastics.
· Has the lowest moisture content.
2. B. Rubbish:
· Consists of 80% rubbish and 20% garbage.
· Contains more moisture than trash but less than refuse.
3. C. Refuse:
· A mix of 50% rubbish and 50% garbage.
· Moderate moisture content due to the equal balance of dry and wet materials.
4. E. Garbage:
· Contains 35% rubbish and 65% garbage.
· High moisture content due to a larger proportion of organic (wet) materials.
5. D. Animal solids and organic waste:
· Composed entirely of animal and human tissues.
· Contains the highest moisture content.
Information Booster:
1. Moisture content affects the decomposition rate and management of solid waste.
2. Trash is primarily dry and non-biodegradable, contributing little to moisture.
3. Garbage and organic waste are rich in moisture and decompose quickly.
4. Higher moisture content increases the potential for leachate formation in landfills.
5. Proper waste segregation helps in effective waste management and composting.
Additional Knowledge:
· Trash (A):
· Includes dry waste like paper, cardboard, and plastic.
· Rubbish (B):
· A mix of primarily dry materials with a small amount of wet garbage.
· Refuse (C):
· Equal parts rubbish and garbage, moderate moisture content.
· Garbage (E):
· Predominantly organic materials, contributing to high moisture.
· Animal Solids (D):
· Contains tissues with extremely high water content.
Key Points:
1. Moisture content influences waste decomposition and landfill management.
2. Dry waste (trash) is easier to manage and store.
3. High moisture waste requires proper handling to avoid leachate and odor issues.
4. Effective waste classification aids in recycling, composting, and landfill management.
