The process diagram illustrates a cyclic process for recycling plastic bottles.
There are nine steps in this procedure . The initial stage of the recycling starts with collection of the waste plastic bottles and in final stage there is production of new products from waste.
The first stage comprises of collection of plastic bottles in a dustbin. After that, a truck comes to collect this waste and to take it to a site where the procedure can be started. Then, in the recycling centre the sorting of these bottles is done with hands. Furthermore, the processing starts and they are compressed into blocks.
The next stage comprises of crushing the blocks and washing the extracted material. After this the plastic pellets are produced in the specialised machinery. Then these pellets are heated and the raw material is formed. The raw material is processed and is used for the production of recycled end materials like T-shirts, pens, pencils etc.
