Eddyville, Fort Dodge, Clinton, Newton, Cedar Rapids. Communities like these have been mainstays of the Iowa bioeconomy for years, even decades — home to corn and soy processing on the largest world scale, and much much more — integrated complexes of advanced refining where companies share infrastructure and often where the residues of the one process become feedstocks for another. They’ve been to farm products what fossil fuel hot spots like the Baytown, Texas mega-complex have meant to oil refining. Now, they have company. A new generation of technologies are coming forward, and a new generation of technologists. Research centers have become the focal point for Iowa’s future, and a slew of new bioindustrial towns — some famed for many years for their role in the bioeconomy, some emerging out of relative obscurity. They’re clean, they’re green, they’re growing, they’re an engine for the economies around them — and unusually and deeply interconnected not only to their R&D roots but to the existing bioeconomy infrastructure. They are linking the city and countryside in an unforgettable manner.
