 Historical Pictures from the Early Use of HWF in Cement Kilns

Jim WJim Woodford runs a standard in preparation for analyzing a hazardous waste fuel sample for metal concentrations using a Perkin-Elmer 5000 Atomic Absorption Spectrophotometer. This picture taken in 1984, demonstrates metal determinations made on all hazardous waste fuel used at the facility starting in 1980.

David Gossman, Systech Facility Manager, examines the output of a fully automated HP5880 gas chromatograph system set up to simultaneously determine PCBs and volatile/semivolatile organic constituents in organic waste streams in less than 30 minutes. The computer was programmed with basic pattern recognition algorithims for PCBs. The system used high resolution packed glass columns at a time prior to the widespread use of capillary columns. This photo was also taken at the Paulding facility in early 1981. In the background is a Perkin Elmer 5000 atomic absorption spectrophotometer used to determine up to 12 metals on every batch of waste fuel prior to use as fuel in the cement kilns at the site.

An early photo of the Paulding, Ohio waste fuel facility tank farm from early 1981. Note the concrete secondary containment and the vapor control lines from the top of each tank. On the opposite side of each tank were side mounted agitators. The fuel lines to the kiln can be seen in the background rising up the side of a slurry tank.
