The rPET full form is recycled polyethylene terephthalate.<\/p>\n\n\n\n<p>Recycled PET is made by collecting, cleaning, and reusing old PET bottles and containers. The used bottles are melted or chemically processed to make new PET resin again.<\/p>\n\n\n\n<p>Using recycled PET helps reduce plastic waste and saves energy.
