The diagram below shows the process for recycling plastic bottles. We can summarise this in 9 simple levels, which start with distinguishing plastic waste in using places. When the recycled waste is picked up by special trucks, it is taken to the recycling centre for sorting. That level is achieved by human forces; simply, workers sort
each piece by hand and put the recyclable pieces into the correct box. Picked material is compressed into blocks and then goes to the crushing machines. The machines include two wheels placed one next to another, 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 washed plastic. At level 8, those pellets are heated to form raw material. The last level is producing the end product.
Consequently, this process leads to avoiding plastics being thrown into nature.
