NORWALK, CALIF. -- Advanced soil chemist Hinrich L. Bohn has a way for flexographic film printers to use solvent-based inks without damaging the environment.
The University of Arizona professor described his low-temperature catalytic oxidizer, or biofilter, during a panel discussion at the Jan. 12 meeting of the California Film Extruders & Converters Association in Norwalk.
