As is displayed in the flow chart, the recycling process of glass is really a complex one.The overall process can be categorized into 3 stages. First, glass products in various forms are gathered in the Collection point, so that they are easily transported by special trucks or vans to the Cleaning plant, where they get sterilization by high-pressured water. There are three different channels in the Recycling plant, namely Brown, Green and Clear, which represent the colors of glass. After recycled in the furnace, glass products are melted into recycled liquid glass. Mixed with new liquid glass, the compound is finally moulded into solid glass, which, afterwards, will be sent to various customer supermarkets for selling.
