Question

Identify the waste materials which belong to the same category.

• A. Old clothes, milk cartons, sewage
• B. Crop residues, tea leaves, vegetable peels
• C. Tea leaves, sewage, waste paper
• D. Old clothes, milk cartons, waste water

Answer 1

The correct option is B Crop residues, tea leaves, vegetable peels

Crop residues, tea leaves and vegetable peels are organic wastes and hence they can be classified together. They can be used as a natural fertilizer. They rot quickly if you bury them, offering rich stores of vital nutrients to the soil, including potassium, calcium, sulphur, phosphorus, magnesium and sodium. You can dry and grind peels or apply them directly to planting areas.
