The diagram illustrates the process of recycling waste glass bottles.
We can observe from the diagram that there are three main stages in the recycling process, beginning with gathering the wasted glass bottles, the recycling of these bottles, and ending with the delivery of new products.
Firstly, wasted glass bottles are gathered at a collecting point. It is then transported to a recycling center/cleaning plant by truck. Next, these are cleaned using high-pressure water to eliminate the dust and other substances before being classified into three kinds of bottles according to their color, such as brown, green and clear.
Later, these bottles are sent to a glass factory to be crushed into smaller pieces. The process continues wherein those pieces are burnt in a specific furnace at a high temperature of 600c – 800c to become molten glass. The recycled molten glass and new liquid glass are coupled together and poured into a glass mould to produce new bottles.
The new bottles are then filled with drinks, and the entire process of recycling glass concludes after these filled bottles are delivered to the supermarket.
