Pollution Prevention Activities for Selected Chemical
| Reporting Year | Section 8.10: Newly Implemented Source Reduction Activity | Section 8.10: Methods to Identify Activity | Section 8.11: Optional Pollution Prevention Information* |
|---|---|---|---|
| 2022 |
Source Reduction:: S21: Optimized process conditions to increase efficiency[-0-4%]
Source Reduction:: S24: Modified or updated equipment or layout[-0-4%] |
Methods to Identify SR Opportunities: T10: Vendor assistance
Methods to Identify SR Opportunities: T10: Vendor assistance Barriers: B3-Barriers to P2 B3 - Concern that product quality may decline as a result of source reduction. |
S21: Optimize precious metals plating process to reduce plate-out events which result in Nitric being sent out for precious metal reclaimation. S24: Updated equipment utilizing a nitric based chemistry to reduce dragout and extend use of bath. Source Reduction - Work with vendor to reduce plate-out events from the precious metal process Source Reduction - Vendor assisted engineer with process design . Barriers to P2: B3 - Concern that product quality may decline as a result of source reduction. - Product quality becomes a concern when contaminant levels are increased while extending useful life of chemical. |

Methods to Identify SR Opportunities: T10: Vendor assistance
|
Source Reduction - Improved process control on processes that required Nitric stripping due to plate out. Precious metal plate out events required additional nitric use in 2021. Steps have been made to reduce these incidents. |
| 2020 |
Other Barriers to Source Reduction - Precious metal plate out event resulted in Nitric acid being sent off site for Precious metal reclamation and neutralization of acid post recovery.Rework of product caused higher usage and dump and remake of multiple baths resulted in elevated usage. |

Source Reduction:: W13: Improved maintenance scheduling, recordkeeping, or procedures[-0-4%]
|
Methods to Identify SR Opportunities: T04: Participative team management
Methods to Identify SR Opportunities: T06: Employee recommendation (under a formal company program) Barriers: B6-Barriers to P2 B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas |
W13: Worked to create criteria to extend chemical bath use Source Reduction - Involved process engineer to change the criteria for chemical bath life. Source Reduction - Process Engineer developed and recommended changes in chenical bath change out criteria. Barriers to P2: B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas - The next step will require evaluation of chemical bath reformulation. This will take time and require customer buy-in to make changes if an alternative can be found. |
| 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 |
Methods to Identify SR Opportunities: T04: Participative team management
Methods to Identify SR Opportunities: T10: Vendor assistance |
W13: Working with Process Engineers to reduce/eliminate time based dump schedules and replace them with contaminant based dump and remake. W21: Work is ongoing to reduce on hand quantities to ensure material does not expire. Source Reduction - Working with vendor to ensure availability of materials due to inventory reductions. Source Reduction - Management has directed Process engineers to evaluate dump schedules and replace time based schedules with contaminant level schedules. |

TRI Pollution Prevention Glossary
The Waste Management Hierarchy |
The waste management hierarchy established by the Pollution Prevention Act (PPA) guides waste generators toward the best options for managing wastes.
The preferred option is to prevent pollution at its source, but for waste that is generated, the preferred management methods are recycling, followed
by burning for energy recovery, treatment and, as a last resort, disposing of the waste.

- A breakdown of production-related waste managed. This includes all amounts of the chemical released directly to the environment or otherwise managed as waste, other than waste generated by one-time events not associated with normal production processes (e.g., fires or remedial actions).
- A production ratio or activity index to provide context for reported toxic chemical quantities. For example, if a chemical is used in the manufacture of refrigerators, the production index would track the number of refrigerators produced and could be used to help gauge how much of the chemical is being released per unit of production.
- Any newly implemented source reduction activities, reported using "W-codes" (e.g., "W41: Increased purity of raw materials")
