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 degradable substances, dry waste and wet waste should also be separated to ensure longer decay time during the transit period. 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. For example, vegetables can be carried in cloth bags, but milk and oil cannot. 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.
Manufacturing: The material of an object can be identified depending upon its property. For example, if we want to manufacture bottles to store liquids, we use materials such as a glass, plastic or metal but cannot use cloth or leaves, as they will not retain the liquid. Similarly, while manufacturing cricket bat, we can use wood or plastic, but cannot use glass.
Usage: In order to make proper use of substances, we need to classify them on the basis of their physical and chemical properties. For e.g. lemon juice and tamarind can be used as souring agents while cooking, but sugar cannot be used for the same.
