थोडक्यात उत्तर

उत्तर

There are two types of garbage:

  1. Biodegradable wastes: Substances that can be decomposed by the action of micro-organisms are called biodegradable substances.
    e.g. Fruit and vegetable peels, cotton, jute, dung, paper etc.

  2. Non-biodegradable Wastes: Substances that cannot be decomposed by the action of micro-organisms are called non-biodegradable wastes. 
    e.g. Plastic, polythene, pesticides etc.
    Most of the non-biodegradable wastes results from human activities.
