I bet that even if they convert old plastic film into new plastic film, it's a lossy process where the number of pounds of useful film out is much less than the number that they truck in. This is in contrast to aluminum recycling, which isn't lossy at all. (Well, I'm sure it's not perfect, but this is the claim.)

Anyway, I don't think either of these new recycling thingies should make you feel good about single-use plastic.
