How to describe a process - IELTS writing

The IELTS Writing test often requires you to describe a process in Task 1. Here is an example of a simple description of a process used to recycle glass. Notice the use of the 'passive voice' grammar structure to describe various stages of the process.

In the UK we recycle around 60% of our glass bottles and jars, but with a little effort this could be as high as 90%. Using recycled glass saves energy CO2 and raw materials - as well as reducing landfill.

After bottles are collected, separated from other waste, and sorted by color, they arrive at the reprocessing factory and are crushed into small pieces called cullet. Contaminants are removed from the cullet using magnets – air suction and laser sorters. The cullet is melted in a furnace at over 1500°C and certain key ingredients are added. The liquid glass is then divided into gobs which can be blown or pressed into brand new bottles and jars - and because glass is such a great material it can be recycled indefinitely.

IELTS Writing Tip

Practice describing a process: just imagine what has to be done in order to ...
  • make a cup of tea
  • do the laundry
  • cook chicken
and then practice using the passive voice to describe the process in an impersonal way like the example above.
