Polyurethane is a plastic made from two components, an isocyanate and a polyol. Traditionally, polyols are derived from petroleum, but USSC has developed one using beans: Soyoyl. Its advantages could be far-reaching. Soybeans are, of course, renewable and more environmentally friendly than petroleum, and using Soyoyl in polyurethane would reduce America's dependency on imported oil. John Deere, the world's leading producer of farm equipment, has begun using Soyoyl to make panels for its combines. "It's nice for our customers who harvest soybeans to know that we're using those beans in the combines they're working with," says John Deere spokesman Barry Nelson. "And if the technology works well, we can help encourage its use in the automobile industry, where you have a lot more volume. The potential is unlimited."
