Source Reduction:: S44: Other improvements to operating practices and training
|
Methods to Identify SR Opportunities: T11: Other
|
S44: Because the semiconductor manufacturing process is pretty strict and doesn't allow for many changes to the process, the focus shifts to operating practices and training to minimize any unnecessary use. Source Reduction - Because the semiconductor manufacturing process is pretty strict and doesn't allow for many changes to the process, the focus shifts to operating practices and training to minimize any unnecessary use. |

Barriers: B8-Barriers to P2 B8 - A reduction does not appear to be technically feasible
|
Barriers to P2: B8 - A reduction does not appear to be technically feasible - Reduction of HF is not technically feasible to our production process |

Barriers: B8-Barriers to P2 B8 - A reduction does not appear to be technically feasible
|
Barriers to P2: B8 - A reduction does not appear to be technically feasible - HF is an important material, reducing this material in our process would negatively affect our product. Other Environmental Practices: Waste Treatment - In October 2017, a HF chemical treatment/precipitation unit was installed. This unit assumed all of the liquid HF waste and was treated onsite opposed to it being treated offsite. |

Other Environmental Practices: Waste Treatment - In October 2017 a HF Chemical treatment/precipitation unit was installed. This has increased our onsite treatment, however will drastically decrease the amount of waste that is hauled away to a treatment facility and drastically reduce the toxicity of the waste byproduct. |

Source Reduction:: W13: Improved maintenance scheduling, recordkeeping, or procedures
|
Methods to Identify SR Opportunities: T05: Employee recommendation (independent of a formal company program)
|
W13: Improved loading procedures for wet etch/strip/cleaning tools. This requires tools to be loaded to capacity before running its process. Other Environmental Practices: General Environmental Management - In CY2016 Infineon changed the way chemicals are calculated for use. This lead to more stringent purchasing procedures and, because all purchased chemicals are assumed used the annual amount has been reduced. |

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")
