The flow chartcharts depicts the nine‑stage process involved in recycling plastic bottles.

2

Overall, plastic bottle recycling consists of nine consecutive steps commencing with consumers depositing empty plastic bottles in recycling bins and culminating in the manufacturefabrication of new consumer goods. The entire cycle can be grouped into three major phases, namely waste collection and sorting, physical processing of plastic waste, and the creation of raw materials followed by finished products. Discarded plastic containers are Deleteconsequently transformed into a diverse array of completely different everyday commodities.

3

Initially, empty plastic bottles are deposited into recycling containers by the public, before being gathered by a waste truck and transported to a recycling centre. Upon arrival at this facility, staff sort incoming plastic waste, manually separating and discarding non-recyclableunqualified items. Following this sorting stage, selectedqualified bottles are compacted into dense blocks, which are subsequently crushed into fragments and thoroughly washed to eliminate surface impurities.

4

Once washedcleansed, these plastic fragments are fed into machinery to produce plastic pellets. Subjected to heating, the pellets are converted into blocks of raw materialinto raw material, from which a broad variety of end‑use goods are manufactured, ranging from plastic storage containers and garments to carrier bags and pencils.
