Waste Management Comparison - 2022
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:: S44: Other improvements to operating practices and training
|
Methods to Identify SR Opportunities: T11: Other
|
S44: Trained chemists on solution control for cyanide tanks in order to reduce quantity of additions made. Source Reduction: Source Reduction - Continuing to work on replacing zinc cyanide with acid zinc bath |
| 2021 |
Other Barriers to Source Reduction - Continuing to work on qualifying new chemistry for production to replace one of two cyanide zinc baths. |

| 2016 |
Source Reduction: Ways P2 Was Incorporated in Original Process Design - Cyanide compounds are used in parts processing including stripping, cleaning, and plating. |
||
| 2015 |
Barriers: B3-Barriers to P2 B3 - Concern that product quality may decline as a result of source reduction.
|
Barriers to P2: B3 - Concern that product quality may decline as a result of source reduction. - Cyanide compounds are used in parts processing including stripping, cleaning, and plating. |
|
| 2014 |
Barriers: B3-Barriers to P2 B3 - Concern that product quality may decline as a result of source reduction.
|
Barriers to P2: B3 - Concern that product quality may decline as a result of source reduction. - Cyanide is required by customers in copper strip tanks and silver strip tanks. The non-cyanide containing options are not viable for our facility. |

| 2012 |
Source Reduction:: W19: Other changes in operating practices
|
Methods to Identify SR Opportunities: T11: Other
|
Source Reduction - An inventory control program was written and used. From this we determined minimum stock needed on hand so less was ordered and less was wasted. |
| 2011 |
Source Reduction:: W42: Substituted raw materials
|
Methods to Identify SR Opportunities: T10: Vendor assistance
|
Source Reduction - Alkaline Zinc was installed instead of using a cyanide zinc system. Enthone was the vendor of the new alkaline zinc system |

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")
