Question

Distinguish between degradable and non degradable waste. Give examples.

Answer 1

Hint: It is important to categorise waste into degradable and non degradable. This will help to reduce the chances of risk involved in waste management. Degradable substances are those that break down easily and non-degradable are the ones which do not.

Complete Step by Step answer: Wastes that can be broken down into organic compounds like methane, carbon dioxide are called degradable waste. They are also referred to as Biodegradable waste. These wastes can be decayed by small micro-organisms and broken down into simple components. Degradable wastes originate from plant and animal matters and decayed by other organisms. Examples of such wastes include: fruit and vegetable peels, used tea leaves and others.
Non degradable wastes cannot be broken down by natural factors. They cannot be decayed or decomposed and remain on the surface of the earth for years and cause critical damage to the environment. They are also known as non biodegradable waste. Examples include: plastic, bottles, olf clothes, footwear etc.
Decomposition of degradable wastes are more rapid compared to non degradable ones. The former one can be decomposed by microbes while the latter cannot be. Degradable wastes can be turned into biogas and energy manure to be used as compost while non degradable ones are toxic and expensive to decompose. Waste affects human and animal life and therefore must be treated effectively. Effective waste management is a responsibility of every individual as well as the government. The most simple steps are the three R’s : Reduce, Reuse and Recycle. This will be helpful in saving energy and resources and provide a greener environment to the entire biodiversity.

Note: Waste management is important for saving the environment and this must be undertaken by every individual. While answering this question be careful to mention the differences of degradable and non-degradable waste clearly and do not get confused with different processes of waste management.
