|---|---|---|---|
| 2022 |
Source Reduction:: S24: Modified or updated equipment or layout[-0-4%]
|
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. |
S24: An inline process was updated to reduce potential for drag-out of chemistry and extend bath life. Source Reduction - Vendor assisting Engineer with design changes to improve process. Barriers to P2: B3 - Concern that product quality may decline as a result of source reduction. - Concern that increase in comtaminants due to extension of bath life could potentially affect product quality. |
| 2021 |
Source Reduction:: S43: Introduced in-line product quality monitoring or other process analysis system[-0-4%]
|
Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s)
Barriers: B3-Barriers to P2 B3 - Concern that product quality may decline as a result of source reduction. |
S43: Utilize specific gravity monitoring to determine level of contaminant build up. Due to variation in product processed through the line contaminant level build up is not linear. Source Reduction - Through measuring the contaminant build up it allows maximum usage of chemical, reducing dump and remake of bath.

W14: Working with process engineer we established improved criteria dictating when a bath requires to be changed, thus extending useful life and reducing amount used. Source Reduction - Worked with process engineer Source Reduction - Process engineer worked with vendor to develop the process and criteria Source Reduction - Utilize a edvice measuring specific gravity , as contaminants build the S.G increases. Specific gravity dictates when the bath is reached its end of use. Source Reduction - Process engineer developed criteria to extend bath usage. Barriers to P2: B3 - Concern that product quality may decline as a result of source reduction. - Concern that further build up of contaminants could cause quality issues. |

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")
