The increasing demand of metal has created concern among scientists all over the world. They are involved in a surge to find out ways to make metal production effective enough to sustain it for generations to come. However metal recycling is one such way to create metal from metal waste which is identical to the metal that is created from raw materials.
Since it is both cost effective and energy efficient people all over the world are selling unused metal articles to get cash and also protect the environment simultaneously. It has been estimated that millions of cans are sold in the market every year. And when each of the can is recycled it becomes a drink can again suitable for sale in the market. Thus it is a very new process of recycling meal that is popularly called as closed-loop recycling mechanism.
How is recycling of a can done?
In the first stage aluminium cans are collected. There are many exchange centres in the world that give you cash in exchange of these aluminium drink cans. These cans once sold are then sent to recycling plants for further processing. Know about can recycling methods here.
Later the recycling process is carried out which is divided into four sections namely shredding, decorating, melting and even casting. In the shredding stage the cans are flattened by use of mechanical hammers. Later on it is decorated by blowing hot air to remove decoration.
Later on the pieces are melted in highly heated-up furnaces. Then water jets are use to cool down the metal. As it gets cooled it takes shape of the moulds. Later on it is send to the rolling mill. At very high temperatures the ingots are given rolling. They are then made into thin sheets of aluminium. Then aluminium sheets are sent to the plant in the coiled form. A lubricated cupping shape to make them into shallow cups. Then the sides of the cups are lifted up. Lacquer is used to coat the outside and inside surface of the can.
This serves as a base coat thereby preventing the decoration from mixing up with the content of the drink can. After the decoration of the can is over it is heated up in oven to dry it up completely. To clean the cans high reassure of water and air is used. Then carbon dioxide gas is used to fill the can. Finally liquid contents are added in the can and it is sealed in mechanical manner. Thus they are ready to be dispatched to the outlets of the retailer. Thus these cans again flood the market and are ready for purchase again. You need to play your part by purchasing them and then selling them at exchange centres.
Thus it is responsibility of each and every individual on this planet to ensure that the recycling loop continues to go unhindered thereby enriching the environment. You can also act responsible by contributing to the recycling loop in your own way. Make combined efforts to save the environment.
