| 2018 |
Source Reduction:: W81: Changed product specifications[-25-49%]
|
Methods to Identify SR Opportunities: T05: Employee recommendation (independent of a formal company program)
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. |
W81: Working to change from nitric acid passivation towards citric acid passivation, by end of 2019 Source Reduction - Required assistance from suppliers to ensure specification compliance Source Reduction - Suggested to management to switch processes to reduce cost/toxicity and maintain quality certifications. Barriers to P2: B3 - Concern that product quality may decline as a result of source reduction. - Working to remove nitric acid passivation by end of 2019, to replace process with citric acid passivation to reduce toxicity |
| 2016 |
Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies.
|
Barriers to P2: B7 - No known substitutes or alternative technologies. - NItric acid is a critical component to our process with no alternatives |
|
| 2015 |
Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies.
|
Barriers to P2: B7 - No known substitutes or alternative technologies. - There is no substitute for nitric acid in metal finishing |
|
| 2014 |
Barriers: B7-Barriers to P2 B7 - No known substitutes or alternative technologies.
|
Barriers to P2: B7 - No known substitutes or alternative technologies. - Nitric acid is an integral part of our metal finishing operations and there are no viable alternatives to much of the work we do with nitric. |
|
| 2013 |
Other Barriers to Source Reduction - Nitric Acid is an integral part of metal finishing, starting in 2014 we have substituted other chemistry where possible, but it is unlikely that we would be able to reduce nitric acid use further due to the nature of our business. |

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")
