Identify the waste materials which belong to the same category.
Spoilt food, 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.
