The Material Facts About Bioplastics
by Green Plastics
Joel Makower has put together a fantastic article at greenbiz.com, taking questions from the viewers of their webcast, “A New Life for Plastics: End-of-life Solutions in the Age of Greener Materials,” and providing answers given by three experts in the field: William Hoffman, environmental scientist in green chemistry at UL Environment; Robert Whitehouse, Director of Applications Development for Metabolix, Inc., a leading bioplastics company; and Kelly Lehrmann, consultant with the German bioplastics firm FKuR.

But here are some of the questions that you can see answers to in the article:
- What is the best benefit from a bioplastic: the biodegradability or the renewable source reducing the carbon footprint?
- What about anaerobic degradation in a closed landfill?
- How long does it take ASTM D6400 to fully degrade into safe emissions in comparison to the other biodegradable products?
- What are the exact conditions of a landfill to facilitate biodegradation? How many landfills with these conditions currently exist (and in which markets)?
- Can you speak a bit about the recyclability of biobased plastics? For example, Coke now has a PET PlantBottle that is 100% recyclable. How is this resin different from other biobased plastics?
- Related to the issue of recyclability of bio-plastics, what is the latest on developing a recyclability standard, whether for biobased plastics or fiber-based, etc?
- With respect to the bio-sources of the plastics described by these presenters, are there any conflicts with sources for food products?
