Biodegradable and Non-Biodegradable Materials

Types of wastes : All wastes can be classified into two types:.

  • Biodegradable Waste : Waste that can be decomposed by the action of microorganisms (bacteria and fungi) into simpler and harmless substances so that it cannot harm the environment is called biodegradable waste. All the wastes derived from living matter are biodegradable. Peels and cuttings of fruits and vegetables, leftover food, leaves, animal dung, bones, plant residue and agricultural wastes are some examples of biodegradable waste.
  • Non-biodegradable Waste : Waste that cannot be decomposed by the action of microorganisms into harmless substances is called non-biodegradable waste. Disposal of this type of waste is a serious problem because this type of waste does not rot or decay. The garbage that consists of plastic, glass and metal objects is non-biodegradable. If not handled properly, non biodegradable waste causes pollution.
