Philip Madson joined KATZEN in 1980 as a chemical engineer. Three years later, his vision and dedication rewarded him the position of Vice President, overseeing marketing and technology. Philip became President and CEO of KATZEN in 1993 where he concentrated KATZEN’s focus to value-added agricultural processing such as motor fuel, potable and industrial grades of ethanol. He has also been involved in projects involving vanillin, solvent extracts, SO2 scrubbing, CO2 liquefaction, cane sugar processing, waste treatment systems, and cheese whey processing and conversion to ethanol. Philip has vast experience from conceptual design to liaison during procurement, construction and production, in all areas of plant development. Philip routinely lectures and teaches leaders in the industry, and serves as advisor to legal and financial firms and provides expert witness services.

Prior to his employment at KATZEN, Philip worked for the Procter & Gamble Company for 9 years, becoming, at the time, the youngest employee to be promoted to the position of Associate Director, for Product Development. His work during those years included on-site liaison, definition of processes, cost/capacity improvement, process troubleshooting, and new product/process development in both cellulose and plastic systems.
