The flow chart illustrates how plastic bottles are recycled.Overall, recycling plastic bot
tles is a cyclical process that consists of use, collection, sorting, compressing, crushin
g, cleaning, pelletising, making new plastic products, and reuse.After plastic bottles are
used, they are discarded in recycling bins, waiting for trucks to transport them to a rec
ycling plant. Once there, they are sorted by hand, and those that can be reused are compre
ssed into blocks. A crusher then breaks down the blocks into small pieces, which are subse
quently washed to remove any residue. The small, cleaned pieces of plastic produced in the
last stage are then poured into a machine where they are turned into pellets. The machine
also heats the pellets, melting them in order to create plastic raw material. After this,
the raw material is packed into bundles and sent to different production lines. It is use
d to manufacture a range of plastic products, including pens, bottles, clothes, and reusab
le shopping bags. Finally, when used and disposed of, these products go through the recycl
ing process all over again
