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* |
|---|---|---|---|
| 2015 |
Other Environmental Practices: Recycling - Increased employee awareness allowed us to recycle more solder related items containing lead. |
||
| 2011 |
Source Reduction:: W42: Substituted raw materials
|
Methods to Identify SR Opportunities: T04: Participative team management
|
W42: Lead free solder has been used in producing test circuit boards. Source Reduction - We have a lead free team working on lead free circuit board manufacturing processes. Source Reduction - The site has built test boards using lead free solder. These boards have been tested for reliablility. It is our hope that customers will approve lead free solder for use in their products in the next few years. |
| 2010 |
Source Reduction:: W42: Substituted raw materials
|
Methods to Identify SR Opportunities: T04: Participative team management
|
Other Environmental Practices - The site has produced test ciruit boards that are lead-free as part of on-going research into the use of lead-free applications in the manufacture of high reliability electronics. |
| 2009 |
Source Reduction:: W42: Substituted raw materials
|
Methods to Identify SR Opportunities: T04: Participative team management
|
Other Environmental Practices - The facility has formed a lead-free solder team that has produced circuit boards for testing using lead-free solders. These test boards are being evaluated to identify lead-free opportunities in our manufacturing processes. |
| 2008 |
Source Reduction:: W49: Other raw material modifications
Source Reduction:: W83: Modified packaging |
Methods to Identify SR Opportunities: T05: Employee recommendation (independent of a formal company program)
Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s) Methods to Identify SR Opportunities: T05: Employee recommendation (independent of a formal company program) Methods to Identify SR Opportunities: T04: Participative team management |

| 2007 |
Source Reduction:: W49: Other raw material modifications
|
Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s)
Methods to Identify SR Opportunities: T04: Participative team management |
Other Environmental Practices - Instituted recycling of lead trimmings that previously had gone to waste disposal. Trimmings are now collected and sent for recycling off-site. This reduced the amount of lead shipped off-site as hazardous waste and increased the amount of lead recycled. This was identified through a process improvement team. |
| 2006 |
Source Reduction:: W58: Other process modifications
|
Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s)
Methods to Identify SR Opportunities: T09: Trade association/industry technical assistance program |
Source Reduction - A Site Assistance audit by the Texas Department of Environmental Quality, identified methods to better handle containers of lead / tin solder paste. This has resulted in less waste from the containers and more lead / tin solder sent for recycling. |
| 2005 |
Source Reduction:: W19: Other changes in operating practices
Source Reduction:: W83: Modified packaging |
Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s)
Methods to Identify SR Opportunities: T05: Employee recommendation (independent of a formal company program) |
Other Environmental Practices - Two changes have resulted in increased recycling of lead waste as well as reduced disposal. Spent solder paste cartridges which still contained residues of lead solder and were sent off site as hazardous waste were instead accumulated and shipped off site for recycling. Second, the solder paste cartridges were then replaced with jars of solder paste which further reduces the amount of residue left in the container. This will further reduce the amount of lead waste materials. |

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")
