3. Prototype Explanation:
This a domestic rubbish bin. Recent area Council's new rule, wants the people of area divide their rubbishes into three categories of recyclable, non-recyclable, and food. These bins are located outside of the house. It is awkward job to put all the rubbishes into one bag and then separate the rubbishes outside of the house into three bins.
Therefore the current rubbish necessarily needs to be replaced with new one which separate rubbishes into the mentioned categories and make the job for householders.
The bins provided by our city council are explained as below:

Recyclable bin:
Non-recyclable bin:
Food bin:
