Waste Management Comparison - 2015
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[-50-99%]
|
Methods to Identify SR Opportunities: T03: Materials balance audits
|
S04: Substituted Lead solder with Tin Solder Source Reduction - Purchased less Tin solder |
| 2021 |
Source Reduction:: S05: Modified content, grade, or purity of a chemical input
|
Methods to Identify SR Opportunities: T03: Materials balance audits
|
S05: Replaced Tin Lead Solder with Pure Tin solder when occassion requires replacement as per customer's request or as per specification. Source Reduction - Replaced Tin Lead Solder with Pure Tin solder when specification allows. |
| 2020 |
Source Reduction:: W58: Other process modifications
|
Methods to Identify SR Opportunities: T11: Other
|
W58: Reducing Lead based solder and substituting Tin solder Source Reduction - Conform with ROHS standard using Lead free solder Source Reduction: Source Reduction - ROHS - reduce Lead solder use and move to Lead free solder processes |
| 2019 |
Source Reduction:: W58: Other process modifications[-25-49%]
|
Methods to Identify SR Opportunities: T03: Materials balance audits
|
W58: Less use of Lead based solder - used more ROHS Lead free solder. Source Reduction - Purchased less Leadd based solder bars. Source Reduction: Source Reduction - Less use of Lead based solder, replaced with Tin based solder. Other Environmental Practices: Recycling - Solder wastes are sent to metals recovery. |
| 2018 |
Source Reduction:: W19: Other changes in operating practices
|
Methods to Identify SR Opportunities: T11: Other
|
Source Reduction - Replaced Lead based solder with Tin based solder, as per customer's request. Other Environmental Practices: Recycling - Sent all solder dross and waste related to manufacturing for metals recovery. Source Reduction: Source Reduction - Replaced Lead Solder with Pure Tin Solder - Lead Free Solder |
| 2015 |
Source Reduction:: W42: Substituted raw materials[-5-14%]
|
Methods to Identify SR Opportunities: T03: Materials balance audits
|
W42: Replaced Lead Solder with Tin Solder Source Reduction: Source Reduction - Replaced Lead solder with pure Tin solder for ROHS compliance. |
| 2014 |
Source Reduction:: W58: Other process modifications
|
Methods to Identify SR Opportunities: T11: Other
|
|
| 2013 |
Source Reduction:: W42: Substituted raw materials
|
Methods to Identify SR Opportunities: T03: Materials balance audits
|
W42: Using ROHS - Non Lead solder materialUsing pure Tin solder material |
| 2012 |
Source Reduction:: W42: Substituted raw materials
|
Methods to Identify SR Opportunities: T11: Other
|
W42: Substituted pure Tin solder instead of Tin/Lead solder in some of the orders received, thereby reducing the amount of Lead solder bars for processing. |
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")
