The diagram explains the different steps in the process of recycling used plastic bottles. It shows how the bottles are collected, cleaned, and changed into new products.
First of all, people throw away plastic bottles into special recycling bins. After that, these bins are emptied by garbage trucks, and the bottles are taken to a recycling centre. At the centre, the bottles are sorted by workers. Only plastic bottles that are good for recycling are chosen. Next, the selected bottles are pressed together into large blocks. These blocks are then crushed into small pieces using a machine.
After being crushed, the small plastic pieces are washed to remove any dirt. Then, they are put into a machine that makes small plastic pellets. In the next step, these pellets are heated to make raw material, which is used for creating new products. In the final stage, the recycled material is used to make useful items like new plastic bottles, clothes, bags, and writing tools.
Overall, the recycling of plastic bottles involves nine clear stages, starting from collection and ending with the production of different new items that can be used again. It is a useful process that helps reduce waste and reuse materials.
