Trials have shown that the plant plastic would decompose in one year using a composter, and *a few years longer* if left in normal outdoor conditions. "normal outdoor conditions" means above-ground, but that's very different from landfills. And these compound-material bottles (cardboard with plastic lining) will be left out of the redeem-recycle cycle altogether. This looks like a much worse solution than all-PET bottles, especially plant-sourced PET.
