A Source Reduction Success - <br /> Century Laminators, Inc. <br /> Century Laminators, Inc. is a small (about 140 employees) printed circuit board manufac- <br /> turer located in Anaheim. Although Century Laminators had already implemented some <br /> source reduction opportunities,the structured, systematic approach of SB 14 provided <br /> added benefit.The source reduction plan submitted to OPPGT by Mr. Chris Hensley,facil- <br /> ity manager,scheduled the following source reduction options for implementation: <br /> • increase concentration of copper in etchant. This would result in an annual <br /> savings ofsq,2oo,and reduce waste by 10% (37 tons). <br /> • reduce cleaning schedule. This would result in an annual savings of$7,700,and <br /> would reduce sludge production by 2% (1.5 tons/year). <br /> • install automatic flow sensors for rinses. This would result in an annual sav- <br /> ings of$8,250,and would reduce the potential for operator error that would <br /> increase sludge generation. <br /> • install automatic fluid dispensers (floor cleaner). This would result in <br /> an annual savings of$8,850. Operator error had resulted in excess sludge <br /> generation due to improper mixing of the floor cleaner. <br /> • install panel sensors on conveyorized processing equipment. This would result <br /> in an annual savings of$2,455. <br /> • modify oxide racks to increase drainage efficiency(cost benefit not <br /> quantified). <br /> • increase rack drip times. Potential reduction of dragout of 50%. <br /> In August of 1998,OPPGT requested follow-up information from Century Laminators, Inc. <br /> Mr. Hensley, now the Vice President of Business Development, is enthusiastic about the <br /> source reduction planning program. In a letter to OPPGT, he states "The program has in <br /> fact been instrumental in changing our thinking in terms of modifying what we currently <br /> do,and in evaluating processes,equipment,and chemistries for future use. The modifica- <br /> tions that were completed first due to their ease of implementation and low cost were not <br /> y the greatest opportunities for reduction, but they did provide a smooth transition into the <br /> U program and were carried out with enthusiasm and precision. These included increased <br /> drip times on our oxide line, rack modifications, and the installation of an automatic floor <br /> i cleaning dispenser."Century Laminators, Inc.'s manifest data indicate source reduction <br /> i O progress: <br /> O <br /> i Ship Year Total Tons <br /> G� <br /> 1995 525 <br /> 1996 459 <br /> i <br /> G� 1997 481 <br /> 1998 283 <br /> S Century Laminators' 1998 waste showed a 38%decrease from 1996 levels.
