If money isn't an object (government subsidy) near anything can be made. That does not mean making it is smarter than making fuel from corn (that is mighty goddamned stupid - you can eat it or burn it but not both).
Biodiesel, gal/acre
===============
Corn, 18
opium poppy, 124
avocado, 282
oil palm, 635
Poly(lactide), poly(glycolide), poly(lactide-glycolide), and stretch-oriented whatever. If you use natural bugs it's crap. If you use gene-gineered bugs it's Franken-polymer.
Plunge into cellulose biosynthesis and insert some clever intermediate biochemistry, mabye a spider silk cassette. Trees are big even if they end up kinda spiralled on the ground on your Franken-polymer plantation. Or go for modifying lignin - that's nice and aromatic hydrocarbonish.
When Enviro-whiners inevitably show up to condemn MONOCULTURE FORESTS!... well, that's volunteer experimental meat on the hoof, isn't it?

One bioplastic is polylactic acid. This is a polyester formed between the -CO2H and the -OH of lactic acid. This was commercialized by Dow Plastics and Cargill some years ago. You'll have to get it from them.
The next is similar. It is poly(hydroxypropionate) poly(hydroxybutyrate), produced by fermenting bacteria. The bacteria make the polyester resin as a storage carbohydrate. That was made by ICI. I don't know if any one makes it any more.
You need to do your thesis at universities that do this sort of thing. The University of Akron comes to mind. The University of Massachusetts at Amherst or Lowell are good.
