Source Reduction:: S23: Implemented new technology, technique, or process
|
Methods to Identify SR Opportunities: T11: Other
|
S23: Lead bearing wave solder process is falling out of favor with our customer base. Usage of the process declined significantly within the RY and is expected to continue decreasing. Process is expected to be decommissioned within RY 2023. This will reduce onsite qtys from 800-1000lbs to 200 - 400lbs as the majority of our onsite qty is contained within the wave solder bath (666lbs). Source Reduction - Products currently running on lead bearing wave solder will either be converted to run lead free wave solder or selective solder which produces much less dross and uses only a 30lb solder pot vs 1800lbs. |
2021 |
Other Barriers to Source Reduction - More of our products are changing to lead free solder alloys over time. Since we are a contract manufacturer, the decision to change a product to lead free is not our to make/specify. |

2020 |
Other Barriers to Source Reduction - Part of our customer base requires use of the material in their products. |

2019 |
Barriers: B1-Barriers to P2 B1 - Insufficient capital to install new source reduction equipment or implement new source reduction activities/initiat
|
Barriers to P2: B1 - Insufficient capital to install new source reduction equipment or implement new source reduction activities/initiat - We are considering replacing wave solder with a selective solder process that would reduce the quantity of solder required on site. This requires significant capital investment for which funds are not available in the current business climate. |

2017 |
Barriers: B6-Barriers to P2 B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas
|
Barriers to P2: B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas - Addition of nitrogen inerting of our wave solder equipment resulted in significant reduction in dross generation and resulting off site transfers over the last 3-4 years. Further reduction is not technically feasible. Our barrier at this point is the amount of product we produce which is not something we can intentionally limit. |

2014 |
Source Reduction:: W58: Other process modifications[-5-14%]
|
Methods to Identify SR Opportunities: T11: Other
|
Source Reduction - Added nitrogen inerting of wave solder process which reduces dross production. |
2013 | Other Environmental Practices - Controltek is participating in WA state's Pollution Prevention Planning process. We have plans for source reduction related to tin/lead solder dross in the form of equipment modification/improvement. This will be implemented in RY2014. | ||
2010 | Source Reduction - Source reduction activities for our business are driven by customer demand. More new products are being released as "lead-free" as our customer's markets demand it. There is still a large portion of our business, however, that continues to use tin/lead solder and will continue to do so. | ||
2007 |
Source Reduction:: W52: Modified equipment, layout, or piping
|
Methods to Identify SR Opportunities: T05: Employee recommendation (independent of a formal company program)
|
Source Reduction - Controltek improved the wave soldering equipment to reduce the level of dross production thereby reducing recycled quantities of dross by 36% and total lead by nearly 45%. This was accomplished by installing a new piece of equipment with improved capabilities for managing solder dross. It is expected that reduced dross production and recycling needs for dross will remain consistent with the activity index going forward. |
