​​ Research on the significance of differently coloured bins.

Dear student, 
​Please find below the solution to the asked query        

Dustbins are categorised into two different colours- green and blue​, in order to differentiate the type of wastes put into them. There are two types of wastes based on whether can be degraded naturally in nature or not. These are biodegradable wastes and non-biodegradable wastes. In green coloured dustbin, biodegradable wastes are put and in blue , non -biodegradable wastes are put.  This categorisation helps in easy disposal of wastes. Wastes from green coloured dustbins can be utilised to make manures. 

Biodegradable wastes are those substances that can be broken down naturally into its simpler basic components  with the help of decomposers such as bacteria and fungi.
For example: Vegetable wastes, animal wastes, paper,  etc 

Non- biodegradable wastes are those substances that cannot be broken down naturally into its simpler basic components with the help of decomposers. 
For example: plastic bag, metals like iron, copper etc.
