Which of the following can be easily decomposed by microorganisms ?

  • A.Petricible wastes
  • B.Putrescible wastes
  • C.Inpetricible wastes
  • D.Non-petricible wastes

Answer: B

Easily decomposed wastes are putrescible wastes.

Putrescible wastes are organic materials, such as food scraps, vegetable peelings and garden waste, that rot quickly through microbial decomposition and produce odour. They make up a large part of Indian municipal waste and are suited to composting and biomethanation.

'Petricible', 'inpetricible' and 'non-petricible' are not standard terms. The opposite category is non-putrescible waste, such as glass, metals and most plastics, which microorganisms do not readily break down.
