IELTS Writing Task 1: Process Diagram 2

Model Essay This flowchart shows the differences and similarities in the life cycles of glass and plastic containers, from creation and use to recycling and re-creation. This diagram reveals both similarities and differences in the way that plastic and glass goods [blank_start]are[blank_end] [blank_start]made[blank_end] (make), [blank_start]recycled[blank_end] (recycle), and then made anew. The processes have more differences than similarities, but there are some more significant differences in the earlier stages of the recycling process. The initial collection and transport of both goods are the same. However, after that, glass [blank_start]is[blank_end] [blank_start]sorted[blank_end] (sort) by color and may then [blank_start]be[blank_end] immediately [blank_start]crushed[blank_end] (crush), while plastic [blank_start]is[blank_end] [blank_start]sorted[blank_end] (sort) by quality and must [blank_start]be[blank_end] [blank_start]bundled[blank_end] (bundle) before it can [blank_start]be[blank_end] [blank_start]shredded[blank_end].(shred) Once the glass [blank_start]is[blank_end] [blank_start]crushed[blank_end] (crush) and the plastic [blank_start]is[blank_end] [blank_start]shredded[blank_end] (shred), the processes become more similar again. At this point, both the glass and plastic pieces [blank_start]are[blank_end] [blank_start]washed[blank_end] (wash), and then [blank_start]melted[blank_end] (melt) and [blank_start]reshaped[blank_end] (reshape) into new products. These final steps are nearly identical, although the melting and reshaping of the glass must [blank_start]be[blank_end] [blank_start]done[blank_end] (do) by two separate machines rather than one.
