Bioplastic: a viable alternative to plastics?

 Does anyone here know anything about bioplastics and if they are a viable alternative to fossil fuel plastics?   Would peak phosphate negate something like bioplastic, which relies on plant bases?

re: bioplastic

Poly lactic acid (PLA) is a bio-derived polymer that has been commercially available for at least 10 years.  It is made from corn, and at least somewhat biodegradable in a compost system.  If I remember correctly, it is a mediocre polymer in terms of performance.  Also, the fermentation to make lactic acid and the subsequent polymerization required a lot of energy input to the process.
