If produced in excess, biodegradable waste can create the following problems:

i)                    Rotting of large amounts of biodegradable waste in open emanates foul odour

ii)                   Heaps of biodegradable waste provides a breeding ground for mosquitoes, flies and worms which spread many diseases.

iii)                 Large amounts of biodegradable waste can also cause blockage of drains, which in turn causes unhygienic conditions and multiplication of mosquitoes.

iv)                 Accumulation of biodegradable waste in water bodies could lead to problems like algal bloom, which leads to deficiency of dissolved oxygen and eutrophication.
