Advantages of Sorting Material

Disposal: For proper disposal of objects, it is important to sort them into groups of biodegradable and non-biodegradable substances.

For nondegradable substances, the objects should be sorted into recyclable and nonrecyclable substances, so as to reduce wastage of material.
Storage: In order to allocate suitable containers for storage of objects, it is necessary to sort objects into solid, liquid and gases.

Liquids such as oil and milk can be stored in open mouth containers such as a glass tumbler, but gases such as nitrogen and oxygen cannot be stored as such.
