“Czarnecki came up with several proposals, including this one: at one propylene oxide plant, we annually generated 42 million pounds of spent catalyst, a chemical that triggers the reaction to create the end product. That works out to three railroad tank cars a day. The spent catalyst is a hazardous waste and disposing of it was costing us $3.5 million a year. Czarnecki discovered a way to recover about 30 percent of the spent catalyst, a $3 million annual savings. He also developed other breakthroughs. One permitted recovery of 20,000 pounds of butadiene that we burned in the boilers. Another reduced benzene emissions from our wastewater treatment plant. Yet another decreased chlorine emissions from our wastewater treatment plant. These suggestions were creative and most entailed only slight changes to manufacturing,” (Huntsman, 2014, p. 241).
