Source Reduction:: S21: Optimized process conditions to increase efficiency[-0-4%]
|
Methods to Identify SR Opportunities: T04: Participative team management
Methods to Identify SR Opportunities: T05: Employee recommendation (independent of a formal company program) Barriers: B3-Barriers to P2 B3 - Concern that product quality may decline as a result of source reduction. |
S21: Increase layer square inches per panel (increase product per panel). Chemical dosing per panel regardless of panel size. Source Reduction - Product engineers work to maximze product count per panel. Reduced panel count reduces chemical feed. Source Reduction - Process engineers work to accurately dose chemical into the process. Barriers to P2: B3 - Concern that product quality may decline as a result of source reduction. - Chemical balance is needed to ensure process runs efficiently. |

Source Reduction:: S41: Improved scheduling, record keeping, or procedures for operations, cleaning, and maintenance
|
Methods to Identify SR Opportunities: T05: Employee recommendation (independent of a formal company program)
Barriers: B8-Barriers to P2 B8 - A reduction does not appear to be technically feasible |
S41: Bath make-up and pm is based on contaminate levels. Action is not conducted as a convenience of unscheduled downtime. Source Reduction - Process engineer developed PM schedule and dump/remake criteria. Barriers to P2: B8 - A reduction does not appear to be technically feasible - In line equipment must spray the chemical onto the product to achieve desired effect and ensure quality of product |

Source Reduction:: W13: Improved maintenance scheduling, recordkeeping, or procedures[-0-4%]
|
Methods to Identify SR Opportunities: T11: Other
Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies. |
Source Reduction - Working to improve process control Barriers to P2: B7 - No known substitutes or alternative technologies. - Certain chemistries that contain Sulfuric acid are required to produce the proper surface quality needed. Changing process chemistries that directly effect product is a long process requiring testing and ultimately approval of customers. |

Source Reduction:: W58: Other process modifications
|
Methods to Identify SR Opportunities: T11: Other
|
W58: Removed a production line resulting in a large decrease in acid aerosol Source Reduction - Removed an older process line once the new line was fully proved out. |
2018 |
Source Reduction:: W13: Improved maintenance scheduling, recordkeeping, or procedures
Source Reduction:: W21: Instituted procedures to ensure that materials do not stay in inventory beyond Source Reduction:: W72: Modified spray systems or equipment |

W13: Working with Process engineers to extend chemistry life, had been using time based schedule. Have moved to contaminant level scheduling and tightening up process control limits. W21: Reduced "in stock" on hand chemistry to ensure inventory will not expire prior to use. Source Reduction - Process engineers have been directed to maximize chemical usage life. This is being carried out incrementally. Source Reduction - Process engineer working on process controls. Source Reduction - Working with vendors to ensure availavility of material when ordered. |

Source Reduction:: W19: Other changes in operating practices
Source Reduction:: W43: Substituted a feedstock or reagent chemical with a different chemical |
Methods to Identify SR Opportunities: T04: Participative team management
Methods to Identify SR Opportunities: T05: Employee recommendation (independent of a formal company program) |
W19: Due to production levels some process tanks were shutdown for long periods of time resulting in reduction of chemical use. This is not a true reduction as it relies on production demand. But it is stated here to demonstrate the reduction . W43: Replaced a sulfuric based microetch with a non-sulfuric based microetch |
2014 |
Other Barriers to Source Reduction - Aerosols are produced in our inline spray processes. Aerosol is very amenable to treatment. |
