Re-use of PET Bottles
PET bottles are also recycled as-is (re-used) for various purposes, including for use in school projects, and for use in solar water disinfection in developing nations, in which empty PET bottles are filled with water and left in the sun to allow disinfection by ultraviolet radiation. PET is useful for this purpose because most other materials (including glass) that are transparent to visible light are opaque to ultraviolet radiation.
