Once we read that piece we looked more into PLA and have decided not to use PLA. Your right, their is a lot of information available out there to make an “informed” choice. We are currently testing a revolutionary bag film that just received FDA approval. We have our fingers crossed that the shelf life testing will be a success.

Energy impact and CO2 potential green house gas emmision is measured by LCA, and these are favourable to PLA versus PET.

In relation with cane pulp molded, I can say that both can have their place, it is not possible to make films and specific kind of materials (bottle, materials taht go to the freezer, trays for meat, etc.) with cane pulp molded materials

I agreed with the suspicious tone of the article, but I wish it had mentioned the fundamental problem with most agricultural feedstocks: they are made using oil. Just because something is a plant doesn’t mean it is oil-free. On the contrary, if something is a plant, it is more likely that it DOES use tons of oil in the form of tractor and transport power and synthetic, petroleum-based fertilizers. In other words, plants and biofuels are not only not always green, but are in fact usually not green.
