Band 8 sample answer
The provided diagram illustrates the cyclical stages involved in the recycling of glass bottles. Overall, the process is a closed-loop system that begins with the collection of used glass and concludes with the distribution of new products to retail outlets, ensuring that materials are repurposed efficiently.
The initial stage of the cycle involves the collection of used glass bottles in a designated recycle bin. Once collected, these items are transported to a treatment plant for preliminary processing. Following this, the glass undergoes a thorough cleaning process in a washing and sterilising machine to ensure the material is hygienic for future use.
In the subsequent phase, the cleaned glass is subjected to a crushing and melting machine, where it is broken down and heated to a molten state. This liquid glass is then transferred to a moulding machine, which shapes the material into new bottles. Finally, these newly formed glass containers are loaded onto delivery vehicles and transported to supermarkets, where they are made available to consumers, thereby completing the cycle and allowing the process to begin anew.

Frequently asked questions
What should the overview say?
The recycling process is a continuous cycle that transforms used glass bottles into new products through a series of mechanical and thermal stages, ultimately returning them to supermarkets for consumer purchase.
How long should an IELTS Task 1 answer be?
At least 150 words; 170 to 200 is the safe range. Spend about 20 minutes on it and leave 40 for Task 2, which carries twice the marks.
How do I describe process diagrams?
Say how many stages there are and where the process starts and ends. Use the passive and sequencers: first, after this, once, finally. Keep every stage; a missing step costs task achievement.
