Green PET can be recycled, it just can’t be recycled into clear PET because it has green dye in it... and green streaks would clue the consumer into the fact that you’re using recycled materials which are somehow unclean.
Recycling is a business, it has very little to do with saving the world.
Not only that, very little of what we throw in recycle bins is actually recycled.
It’s become cultural kabuki, for no real benefit.
