Academic IELTS Writing Task 1 – Process & Sample Answers

The diagram illustrates the process of recycling wasted glass bottles. It is clear that there are three distinct stages in the recycling process, beginning with the collection of unused bottles and ending with the delivery of new bottles.

At the first stage in the process, wasted glass bottles are gathered at a collecting point and delivered to a cleaning plant by a truck. At the second stage, glass bottles are washed in high- pressure water before being categorized according to colors which normally include clear, green and brown. After that, the bottles are sent to a glass factory where they are broken into pieces. The process continues with burning these pieces in furnaces at the temperature of 600- 800c, and then liquid is produced. The recycled liquid glass and the new liquid glass from other sources are then shaped in a glass mould to produce new bottles.

At the final stage, new bottles are transported to supermarkets where the products are ready for sale.
