the process for recycling plastic bottles
The flow chart illustrates the procedure of recycling plastic containers. In general, this process consists of nine steps which are happened in several places.
As can be seen from the flow chart, to begin with, plastic containers are disposed of and put into recycling bins, which are collected to recycled trucks. Then, plastic bottles which are gathered to these trucks are transported to a recycling centre. Next, at the recycling centre, plastic bottles are separated from metal, plass or other non-recyclable rubbish; also, they are sorted by the type of plastic they are made from. After that, plastic bottles which are recyclable are compressed into cubic bales in order to be more easy to transport.
Turning to the next five steps of the flow chart, plastic cubic bales are then delivered to a factory where they are ground into plastic flakes. Before these flakes are melt to form plastic pellets, they are washed to remove liquid, food or chemical residue. Once plastic pellets are ready to be heated and bundled up, they are packed into raw material. After that, plastic raw material is distributed to many different factories where this type of material is manufactured to plastic items and other kinds of products. Then, these products are used and placed in recycling bin to start a new cycle of recycling.
