Water cups are more likely to rust after later use. As before, rusty iron oxide can cause serious damage to the human body.

Plastic recycling is the material that passes through the machine required by the production process when producing plastic products, the waste in the machine that is stagnant during production, and the remaining tailings after production is completed. These materials are more polluted and contain impurities and other harmful substances.
