The diagram shows the process by which glass drinks bottles are recycled. leJW1
The given process diagram illustrates the various stages involved in the process of recycling glass drink bottles. In the first stage, recycled glass, soda ash, sand and other raw materials are fed into a furnace where they are heated to 1500° centigrade and melted. The molten material is then sent to a fore hearth, where the temperature is made uniform. The next stage involves using a cutting machine to cut the molten glass into identical pieces before forcing it into the shape of a bottle using a mould. The temperature of the bottles is reduced to less than 1150°c before passing them through a rapid cooling process, in which the temperature is further dropped to below 500°c. Upon cooling down, the bottles are conditioned to make them more durable by exposing them to extreme temperature of up to 1200°c. Afterwards, when the temperature of bottles falls below 500°c, they become ready for surface treatment, which involves first cooling the bottles to 120°c and then spray coating them provide a smooth texture. This is followed by a quality check which identifies faults. Those bottles which do not pass the quality control check are rejected and recycled in the furnace, while the bottles which meet the quality standards are packed and made ready for delivery. Overall, this is a man-made linear process consisting of nine stages, starting from heating the raw material and ending at the delivery of the finished product.
