The diagram illustrates the plastic bottle recycling process. Overall, the recycling of plastic bottles has nine steps starting from placing the bottles in the designated bins to producing end-consumer products like bags, t-shirts, and pencils – which would be recycled again once they are used.
As the illustration depicts, the first step of recycling plastic bottles begins with people placing them in specified recycle bins. Next, those bottles are collected and transported to the recycling centre where workers sort out recyclable plastic bottles from others. Selected bottles are then compressed and converted into large blocks which are, afterward, sent through crushing machines. The crushing procedure produces small pieces of the bottles before feeding them into a machine to make plastic pellets. In the next step, heat is applied to the pellets which ultimately form the raw materials for producing different plastic-made consumer goods.
Next, the raw materials are refined and rolled which is used to manufacture end products like t-shirts, pens, plastic containers, and so on. To summarize, the end products are then placed in assigned dustbins from where the whole cycle again goes on.
