From wikipedia:
> Most recycled PET is used as apparel fiber.
> However rPET has also been sold in the form of carpet fiber. Mohawk Industries released everSTRAND in 1999, a 100% post-consumer recycled content PET fiber. Since that time, more than 17 billion bottles have been recycled into carpet fiber.
Aluminum is 100% recyclable into whatever it was before. I guess just don't have the same standards for what recyclable means or should mean.
IMHO plastics just go into a stupid microplastic generation pipeline grinding cycle.
