The diagram illustrates the sequential stages involved in the recycling process of used glass bottles.
Overall, the process is a cyclical loop consisting of three main stages, beginning with the collection of waste glass from consumers and concluding with the delivery of newly manufactured bottles back to supermarkets.
In Stage 1, the process begins when consumers discard used glass containers at designated collection points. These collected items are then gathered and transported by a large truck to a cleaning facility.
During Stage 2, the bottles are thoroughly washed inside a cleaning plant using high-pressure water. Following this, they are segregated into three specific colors: brown, green, and clear. The sorted glass is then sent to a recycling plant to be broken down before being transferred into a high-temperature furnace. Inside the furnace, the recycled glass is melted and combined with new liquid glass. This molten mixture is then poured into a mould to shape new bottles.
Finally, in Stage 3, the newly formed glass products are distributed back to customer supermarkets, ready to be purchased and used again, thereby restarting the entire cycle.
