The diagram illustrates the various stages involved in recycling plastic bottles, beginning with disposal and ending in the production of new items. The process consists of nine steps, which transform used plastic into reusable raw material and finished products.
Overall, the process follows a linear sequence, starting with the collection of discarded plastic bottles and culminating in the manufacturing of new goods. The procedure involves both mechanical operations such as sorting and crushing, as well as thermal processes including heating to form raw material.
In the initial stage, individuals discard plastic bottles into designated bins. These are then collected by garbage trucks and transported to a recycling centre, where the bottles are sorted from other waste. In the fourth step, the selected plastic is compressed into blocks, which are subsequently crushed into smaller pieces and thoroughly washed.
Next, the clean plastic fragments are processed in a machine that converts them into plastic pellets. These pellets are then subjected to heat in order to produce raw material. Finally, this material is used in the production of various consumer items such as bottles, clothing, and stationery products.
