PET bottles take a long time to decompose and recycling them helps reduce this environmental harm. Studies show that 1kg of recycled PET bottles saves 0.8 liters of oil. The recycling process washes, shreds, and re-melts used PET bottles into new polyester fiber or clothing material. While PET bottles are convenient, they produce greenhouse gases and contain chemicals like antimony. It is better for the environment to reduce and recycle PET bottles when possible by buying less bottled drinks or reusing bottles.
