Source Reduction - We are contract manufacture of electronics assemblies and build to our customers strict specifications, which includes the callout of solder alloy type. As our industry shifts to lead-free solder alloys our customers are redeveloping their products and are specifying lead-free solder alloy. This will have a direct relation to our annual usage. We have seen a large shift is 2021 and expect that that to continue. However, we do build products where leaded solder is specified, so we will continue to use leaded solder when specified by our customers. |

Source Reduction:: W29: Other changes in inventory control[-5-14%]

Methods to Identify SR Opportunities: T10: Vendor assistance

W29: Vendor Managed Inventory programs has reduced the amount of virgin product we stock within the facility. Weekly replenishments of solder alloys are provided by our suppliers. Source Reduction - Vendor Managed Inventory programs has reduced the amount of virgin product we stock within the facility. Weekly replenishments of solder alloys are provided by our suppliers. Other Barriers to Source Reduction - We are a custom manufacture of electronics printed circuit board assemblies and must adhere to our customs bill of materials and alloy specifications. Therefore we have no control on using alternate solder alloys that do not contain lead. |
| 2019 |
Source Reduction:: W81: Changed product specifications[-0-4%]
|
Methods to Identify SR Opportunities: T11: Other
|
W81: A customer specification change is required to change from using leaded solder to lead-free solder. Source Reduction - As technology advances, leaded components are becoming obsolete. this is forcing design / specification change on our customers, thus switching to a lead-free product. Other Barriers to Source Reduction - We are a contract manufacture of electronic assemblies and build to our customers strict specifications, which includes the type of solder that is used. |
| 2018 |
Source Reduction:: W81: Changed product specifications[-25-49%]
|
Methods to Identify SR Opportunities: T11: Other
|
W81: A customer specification change from the use of leaded solder to lead-free Source Reduction - a requirement change from our customer Other Barriers to Source Reduction - We are a contract manufacture of electronics assemblies. Therefore our customers specify the types of solder that are used on their products. A large percentage of our customer base is in the medical instrumentation. Currently medical products are exempt from using lead-free solder, that exemption expires at the end of 2019. We are unsure if the exemption will be extended, however if it is not, we would expect to see a large reduction in the use of leaded solder. Source Reduction: Source Reduction - The electronics industry has been transitioning to lead-free solders for over 10 years. However, medical, military and aerospace devices are exempt from the use of lead-free solders due to the lack of long term reliability data. That is improving each year and the exemption of the use of lead-free solder from the medical sector is expiring at the end of 2019. If no extensions to the exemptions are granted, we should see a reduction in our use of leaded solder. |
| 2017 |
Source Reduction:: W89: Other product modifications[-25-49%]
|
Methods to Identify SR Opportunities: T11: Other
|
W89: We expect a reduction in lead usage in 2019 due to the lead-free (Rohs) regulations. Medical electronics is a large portion of our business and the Medical industry has a RoHS exemption that is expiring at the end of 2018. Source Reduction - Regulations on product that use leaded solder. |
| 2016 |
Source Reduction:: W29: Other changes in inventory control
|
Methods to Identify SR Opportunities: T10: Vendor assistance
|
W29: Supplier is stocking material on a weekly basis, therefore less material is on-site Source Reduction - Supplier is stocking material on a weekly basis, therefore less material is on-site |
| 2015 |
Other Barriers to Source Reduction - Since our customer base is largely medical and aerospace, the use of leaded solder is still required. We are seeing an increase in lead-free soldering from other customers, however we are required to build and solder our customers product to their specification, which includes what solder alloy is to be used. As the leaded solder exemptions expire in the coming years, we will see a decrease in the use of leaded solders as these customers will have to comply to the RoHS (lead-free) requirements. |

| 2013 |
Other Barriers to Source Reduction - Pollution prevention previously implemented- additional reduction does not appear technically or economically feasible- The use of leaded solder is still required by over 70% of our customer base. Although the increase in lead-free solders continues year over year, many of our medical and Military /Aerospace customer still require the use of leaded solder. The medical industry is close to the end of their exemption date for manufacturing systems with leaded solders. If the exemptions are extended, our use in leaded solders will remain consistent with our prior years usage. However, If they are not extended, we will expect to see an decreased use in leaded solder as these products will be converted to use lead-free solder. |

| 2012 |
Source Reduction - Lead-Free solders continue to increase in our industry. Out of our current customer base only 15% are requiring lead-free solders. We continue to see increase in customers designed product that will require lead-free solder. The additional lead-free requirements should have a direct effect on the leaded products we build, resulting in a reduction in use of leaded solders.
Other Barriers to Source Reduction - Source reduction has been an ongoing process at our facility. Our manufacturing equipment and maintenance programs have all been setup to minimize the lead waste. All lead waste streams that are generated are send off site for recycling. Our industry has been and is continuing it's journey in replacing leaded solders with lead-free solders. Since we are custom assembly manufacture, and we do not design the products we build, we must rely on our customers to design out the use of leaded solders. Many of our customers are medical, defense and aerospace, which currently have exemptions in the use of lead-free solders. These exemptions will be expired in the 12 - 24 months, so we anticipate our customers redesigning their products, using lead-free solders. These redesigns will have a direct effect on our use of leaded solders, therefore we will see a reduction in the use of these materials. |

| 2007 | Source Reduction - We have installed a machine that produces less solder dross or waste which will reduce or maintain the amount of material we send out for recycling as we grow. Our industry is also moving toward "Lead-Free" solder which we are seeing a small percent of our customers converting to and we believe this will continue to increase in the coming years. | ||
| 2006 | Source Reduction - We have installed a machine that produces less solder dross or waste which will reduce or maintain the amount of material we send out for recycling as we grow. Our industry is also moving toward "lead-free" solder which we are seeing a small percent of our customers converting to and we believe this will continue to increase in the coming years. |

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")
