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