yup, acidity breaking plastic down is a big no no, for ANY human contact or use in a engineered structural component. the latest "eco plastic" offering fits into the same category as the latest battery tech, wonder food, la la la, foofoo berries. Some of these things WILL pan out eventualy, but the evaluation needs to be cold blooded, and explicit based on access to real test data and real world third party evaluation. Till then it's quasi organic energy enhancing foo foo berry powder, though the expectation is that we all abase ourselves before the deployment of the magic word, sustainability.
