Claims for a non-petroleum-based plastics and other oil-saving techniques

Posted by Trent Walters at 2:36 PM
Building new plastics from starch:

Natural starch particles are roughly 30 microns or millionths of a meter wide. Ecosynthetix bases its technology on converting these granules into ones just 50 to 150 nanometers or billionths of a meter large. At that size, the nanoparticles have 400 times more surface area than natural starch granules. This means they require less water when in use for adhesives and thus less time and energy to dry. Instead of running at 350 degrees F, drying can take place at room temperature instead, saving $1 million in natural gas per year, van Leeuwen said.

The nanoparticle adhesives could also help replace the polyvinyl acetate, PVA, and polyvinyl alcohol, PVOH, used to help laminate graphics onto cardboard.
