Waste Management Comparison - 2017
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:: S04: Substituted manufacturing aid, processing aid, or other ancillary chemical
|
Methods to Identify SR Opportunities: T11: Other
|
S04: more options for using lead free solder Source Reduction: Source Reduction - using lead free solder |
| 2021 |
Source Reduction:: S06: Other material modifications made
|
Methods to Identify SR Opportunities: T11: Other
|
S06: Changes and efficiencies in processing resulted in less use of certain materials Source Reduction - Certain processes have been updated for efficiency |
| 2019 |
Source Reduction:: W68: Improved rinse equipment operation
|
Methods to Identify SR Opportunities: T03: Materials balance audits
Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s) |
W68: We continue to see improvements in the use of the nitrogen filled wave solder devices. Limiting oxidation of solder reduces the amount of dross that needs to be removed from the solder pot. Source Reduction - There is an annual comparison of chemical purchases including solder from year to year Source Reduction - Constant monitoring of risks ands opportunities |
| 2018 |
Source Reduction:: W58: Other process modifications
|
Methods to Identify SR Opportunities: T03: Materials balance audits
|
W58: We continue to see improvements in the use of the nitrogen filled wave solder devices. Limiting oxidation of solder reduces the amount of dross that need to be removed from the solder pot. Source Reduction - There is an annual comparison of chemical purchases including solder from year to year. |
| 2017 |
Source Reduction:: W58: Other process modifications
|
Methods to Identify SR Opportunities: T03: Materials balance audits
|
W58: We continue to see improvements via the use of the nitrogen-filled wave solder devices. Limiting oxidation of solder reduces the amount of dross that needs to be skimmed from the solder pot. Reduced oxidation means we purchase much less solder over the course of the year; a portion of which is a TRI-reportable material. Source Reduction - Annually we review all chemical/part purchases and, in this case, compare our solder purchases from year to year. |
| 2016 |
Source Reduction:: W58: Other process modifications
|
Methods to Identify SR Opportunities: T11: Other
|
W58: Nitrogen filled soldering equipment was purchased which limits the amount of solder oxidation thus reducing the amount of solder needing to be purchased as much less solder dross is formed. This change has reduced the amount of dross and, by extension, lead at our facility by thousands of pounds annually. Source Reduction - Equipment improvements in the industry have allowed for reduced TRI chemical usage. |
| 2014 |
Source Reduction:: W58: Other process modifications[-25-49%]
|
Methods to Identify SR Opportunities: T03: Materials balance audits
|
W58: New solder equipment was obtained and is nitrogen filled which reduces oxidation and the amount of dross that needs to be removed from the pot. Because of the reduced solder dross generation, we were able to reduce the overall amount of solder ordered. Other Environmental Practices: Recycling - Steps were implemented this reporting year to increase the amount of lead recovered from waste in lieu of stabilization. |
| 2013 |
Source Reduction:: W58: Other process modifications
|
Methods to Identify SR Opportunities: T11: Other
|
Other Environmental Practices - Began recycling all lead contaminated waste for metal recovery rather than sending it to a permitted land stabilization TSD. |
| 2012 |
Other Environmental Practices - Measures have been initiated in CY2013 to increase the amount of lead reclaimed as opposed to stabilized. Equipment is being considered which would use less lead.
Other Barriers to Source Reduction - Lead is necessary to produce finished product and its use is directly proportional to output. |
||
| 2008 | Source Reduction - With the increase of production levels in the past few years we have switched some of our articles to use no lead solders. We continue to look at no lead and implement when possible. |
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")
