The diagram below shows the process for recycling plastic bottles. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The diagram illustrates how

plastic

bottles

are recycled. The cyclical artificial process highlights nine distinct steps involved in converting used

bottles

into new products.

To begin

with, used

plastic

bottles

are collected from recycling-labelled trash bins before being transported to a recycling centre by specialised trucks. Once they arrive, the

bottles

undergo a manual classifying stage, where they are separated based on their suitability for recycling.

Following

this

step, the selected

bottles

are compressed into large blocks to facilitate

further

processing. Following the compression, the blocks are pushed into a crushing machine that breaks them down into smaller pieces. They are

subsequently

rinsed in water to remove any impurities before being fed into a machine in which they are made into

plastic

pellets. Afterwards, these pellets are heated from below, forming raw usable

plastic

. In the final stage, the raw material is transformed into a variety of goods,

such

as

bottles

, clothing, bags, stationary products and boxes, thereby completing the recycling process. Eventually, these end products may enter the recycling process once again.
