The provided diagram describes the procedure for recycling plastic bottles.
Overall, this nine-stage circular process begins with plastic waste collection and ends with the production of new items.
To begin with, all plastic bottles are gathered from recycling bins before being transported to a recycling centre. Subsequently, workers carry on sorting them to keep recycleable waste which is then compressed into blocks. In the next step, these blocks are fed into a crushing machine, washed to have clean plastic. After that, specialized machines are responsible for producing plastic pellets from crushed plastic. Then, through heating stage, raw materials are formed from pellets. Finally, raw materials are used to manufacture final products, including different kinds of plastic items or daily essentials such as pencils, disposal bags, and so forth. From this point, the cycle starts over again.
