The diagram below shows the process for recycling plastic bottles. We can summarize this in nine simple levels, which start with distinguishing plastic waste in use in places. When the recycled waste is picked up by special trucks, it is taken to the recycling center for sorting. That level is achieved by human force; simply, workers sort
each piece by hand and put the recyclable pieces into the correct boxes. Picked material is compressed into blocks and then goes to the crushing machines. The machines include two wheels placed next to each other, turning in different directions. The machines crush and divide plastic into small pieces and put them into washing trays.
The next level is producing plastic pellets from the washed plastic. At level 8, these pellets are heated to form raw material. The last level is producing the end product.
Consequently, this process leads to avoiding plastic being thrown into nature.
