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 flowchart illustrates the procedure of how

plastic

bottles

are recycled.

Overall

, there are nine phases in the recycling of

plastic

bottles

, from dumping used

bottles

into the trash bin to producing new products. As is shown in the graph,

the first step is

to place the

plastic

garbage in the dustbin for recyclable waste. Afterwards, the

plastic

bottles

are packed and

then

delivered by trucks to the recycling centre. After being sent to the centre, these

bottles

are sorted by hand into two categories: the recyclable ones and the non-recyclable ones. In the following stage, these recyclable

bottles

are compressed tightly into blocks.

Next,

the blocks are put into a grinder which crushes them into smaller pieces, and

then

the crushed

bottles

are washed in clean water. The sixth step is to put the pieces of

plastic

into a machine in order to turn them into pellets. Once the

plastic

pellets are made, they are heated to create raw material, which is

then

stacked on the shelves.

Finally

, the raw material is used to produce end products,

such

as

plastic

bottles

, clothes, containers and pencils.
