> she estimates that cups made from the new material would cost $2,333 a tonne. That is half the $4,750 a tonne cost of biodegradable cups made from polylactic acid (fermented plant starch), and only slightly more than the $2,177 a tonne that it takes to make plastic cups. There you go. The dagger for non-biodegradable plastics come not just from invention, but from invention and value. ~7% increase in price is enough to disrupt.
