The given flow diagram illustrates the process for recycling plastic bottles.
Overall, it is evident that there are three main parts with nine total steps in this recycling process, containing collecting, sorting and producing.
The first stage begins with collection and sorting. Individuals throw their rubbish into recycling bins, which are then collected and loaded by trucks. Once they are transported to the recycling centre, plastic bottles could be sorted by hand, compressing into blocks in the next step.
In subsequent stage, stacks of plastic bottles will be crushed into minor pieces. After that, the washed pieces will be reproduced into plastic pellets through a particular machine, which will be transformed into raw material via heating.
Ultimately, the final stage demonstrates how the substantial goods are generated and used by people. Upon the raw material are formed from plastic pellets, it will be the resource for producing end products involving plastic bottles, plastic boxes, clothes, pens and plastic bags, which will finally flow into the market and lead to a new cycling system.
