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

The diagram illustrates the procedure for reprocessing

plastic

bottles.

Overall

, it can be seen that

this

is a cyclic man-made process, containing 9 stages.

The first step is

collecting and transporting the waste, followed by processing it and

then

converting it into a new material from which

plastic

bottles are made again and ready for a

further

cycle. First of all, garbage is collected from trash bins and transferred by trucks to recycling centres. After that, the staff is sorting the litter, sending the suitable one for compression and it is

then

turned into compact blocks. The latter is smashed in a special devise into smaller pieces which need to be purified in a washing tank. After that, the little pieces are put in a machine that transforms them into even smaller

plastic

pellets. The next step regards a heating process of the mass where raw material is produced and

then

packed and stored.

This

substance is used for

plastic

objects production and once they're thrown away, the whole process of recycling can start again.
