Special Section
Thomas Walsh
For more than 40 years, process intensification (PI) efforts in the U.S. have lagged behind those in other parts of the world. Europe has invested heavily in this research area, and both industry and academia have embraced advances in these technologies — particularly in the chemical and pharmaceutical manufacturing areas, which have seen increases in productivity, energy efficiency, and sustainability. American manufacturing is now awakening from its long slumber and progress is on the horizon.
