When a used item is stored and processed again for making a new item out of it which can be used again as the original item using a suitable process, then this process is called recycling. For example, plastic bottles are used to drink water. After the water is consumed, it will be crushed and stored. All of them are recycled and made again in the form of any other usable form. We will generally use this process to save resources and make the best use of the available resources without wasting them.
