The given diagram illustrates the process of plastic recycling.
Overall, the process entails six stages, beginning with the buying of plastic, using and discarding of used plastics, and ending with newly recycled products entering the markets once again.
In the first stage, the plastic products displayed are purchased, used, and thrown away. The plastic bags, along with other sorts of garbage, are sent and buried in landfill sites. Discarded bottles, however, are collected for recycling. After being gathered, they are then taken to sorting houses, where they are divided into various categories by either machines or humans.
Once the plastic has been sorted, it is then loaded into trucks and transported to factories, where it is then processed and made into new plastic products. These new, recycled products are delivered and finally distributed back to retail shops, where they are sold, reused, and discarded once again, thereby continuing the whole process.
