The provided diagram illustrates how the process of recycling plastic bottles takes place.
Generally, this continuous process consists of 9 steps, in which steps 1 to 4 are simple preparations while steps 5 to 8 are the most technically important parts.
Specifically, at the beginning of the process, plastic bottles are discarded by users into designated trash bins which are painted with a recycle symbol. Afterwards, the bottles are collected and delivered by a specialized vehicle to a recycle centre, where they are manually sorted. Bottles that are inappropriate for recycling will be left out, while the suitable ones are picked and then compressed into cubic blocks in step 4.
Next, step 5 involves crushing these plastic cubes into small pieces by means of grinding gears. These pieces of plastic fall down into a water tank where they are washed before being put into a special machine which turns them into plastic pellets. The pellets are melted to produce raw plastic. Finally, at step 9, the produced plastic is used to manufacture various types of products including bottles, boxes, pencils, recyclable bags, and T-shirts, and the cycle restarts from step 1.
