Given is a diagram illustrating the process of recycling plastic bottles, which consists of nine steps of collection, transport, sorting, compresssing, crushing, washing, producing plastic pellets, heating and producing various products.

  The whole process begins with collection, people will drop the used plastic bottles and other trash into garbage bins near their house. Then  moreover, usually at the fixed point in the day, rubbish collector will bring all this rubbish away to the recycling centre.

  Next to it, because there are things other than plastic bottles in this garbage, it is necessary for staff to separate plastic bottles from other waste. After finishing classification, for sake of convenience of crushing them, it’s time to compress these separated plastic bottles into blocks. Moreover, these blocks will be turned into pieces after going through the crushing wheel. Then, for separating thing which can not be used for reproducing, these pieces will fall into the water pool under the crushing wheel.

After purifying, these pieces throw into the machine which will transfer these pieces into pellets used for next step. Next to it, there will be some heating devices used for heating pellets. Then, after heating, pellets will become raw materials. Then, the raw materials will be used for manufacturing various end products, like clothes, plastic bags and plastic bottles, and finally sold to consumers once again.
