Sample Answer
The flowchart illustrates the recycling procedure for glass bottles, detailing the seven stages involved in the process.
Initially, glass bottles are collected from the public and sorted into three distinct colours: green, brown, and clear. This segregation is crucial for efficient recycling. Following this, the bottles are transported to a processing plant, where the metal and plastic caps are removed in preparation for further processing.
The next step involves breaking the glass, which is then transported by vehicle to a glass factory. At the factory, the broken glass is mixed with other raw materials and heated in a furnace at a temperature of 1200°C. This high-temperature process allows for the glass to be melted down effectively.
In the final stage, the molten mixture is used to manufacture new glass bottles, completing the recycling cycle. Overall, the process of recycling glass bottles is comprehensive and involves multiple steps, emphasizing the importance of each stage in creating new products from recycled materials.
