Make resin for plastics from sugar cane instead of oil, and sequester CO2 at the same time

I'd love to know the chemistry involved. Typically there's a high energy barrier to transform one kind of chemical into another, but maybe clever use of bacterial enzymes is involved. Still, it's a great accomplishment, and a powerful way to move to a new era of carbon-sequestering production, while still allowing us all the Tupperware we crave. Well, maybe not all, but still!
