Polyethylene terephthalate (PET) bottles are made of one of the few polymers that can be recycled into the same form – a new beverage bottle – again and again. This neatly closes the recycling loop and enables ‘cradle to cradle’ packaging solutions. As with virgin PET, recycled PET (rPET) can be used to make many new products, including polyester staple fibre or filament used for apparel (clothing), home textiles (duvets, pillows, carpeting), automotive parts (carpets, sound insulation, boot linings, seat covers) and industrial end-use items (geotextiles and roof insulation), and new PET packaging and bottles for both food and non-food products. It is generally blended in a ratio of virgin to recycled, depending on the application required.
