Model report

167 words

The diagram illustrates the process by which waste paper is recycled to make new paper products.

Overall, there are nine stages in the process, beginning with the collection of used paper from homes and ending with the delivery of new paper to manufacturers. Most of the stages involve turning the waste paper into pulp and cleaning it, and it is a linear process, with each stage following directly from the one before.

First, waste paper is collected from households, and it is then sorted according to its grade. After this, the paper is mixed with water to produce pulp. The pulp is screened in order to remove any plastics, and the ink is then removed by washing.

Once it has been cleaned, the pulp is bleached and refined. It is then spread onto rollers and pressed, after which the new paper is dried and wound into reels. In the final stage, the reels are cut and sent to manufacturers, who use them to make new paper products.

Common mistakes

  • Using the active voice with "people": "people collect the paper". Processes are usually described in the passive: "the paper is collected".
  • Leaving out stages. Every stage should appear; group them into two body paragraphs instead of skipping some.
  • Missing the overview. Say how many stages there are and where the process begins and ends.
