Other Environmental Practices: Recycling - Our dross makes up the lion share of the metals recovery effort. There is a smaller amount of electronic scrap, PC boards, and solder paste wipes that are estimated to contribute an additional 15% of the Lead total (as per USGS July 2001). |

Source Reduction:: W25: Instituted clearinghouse to exchange materials that would otherwise be discarde

Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s)

Other Environmental Practices - Ducommun is taking active steps to improve all facets of recycling and one avenue is metals recovery from our printed circuit boards. Approximate Lead in recycled printed circuit boards was calculated as follows: If an average board weighs 60 grams, we will assume a conservative position of 1.85 grams of Lead. In RY2013, Ducommun recycled 311 pounds of PCBs (141,070 grams),divided by 60 grams, approximates 2351.17 boards, multiplies by our internal estimate of 1.85 grams Pb per board = 4,349.66 grams => 9lb 9.43 oz or ~10lb. |

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")
