Waste Management Comparison - 2021
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* |
|---|---|---|---|
| 2022 |
Source Reduction:: S35: Other improvements to inventory and material management
|
Methods to Identify SR Opportunities: T11: Other
|
S35: Minimize copper in the incoming feed materials |
| 2021 |
Source Reduction:: S11: Reformulated or developed new product line
|
Methods to Identify SR Opportunities: T03: Materials balance audits
Barriers: B3-Barriers to P2 B3 - Concern that product quality may decline as a result of source reduction. |
S11: SRT may investigate use of aluminum alloys that use less copper. Barriers to P2: B3 - Concern that product quality may decline as a result of source reduction. - Aluminum alloy composition is specified by client and deviation could result in products not meeting requirements. |
| 2019 | Other Environmental Practices - SRT has continued to improve hood design and install new hoods on electric induction furnaces. | ||
| 2018 |
Source Reduction:: W52: Modified equipment, layout, or piping
|
Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s)
Barriers: B1-Barriers to P2 B1 - Insufficient capital to install new source reduction equipment or implement new source reduction activities/initiat |
W52: Redesigned hoods over furnaces increasing capture efficiency and therefore collecting more of dust before escaping into the atmosphere. Source Reduction - Internal audits regarding the improvement of hood designs on the furnaces to increase the collection efficiency of waste gases coming from the furnace. Barriers to P2: B1 - Insufficient capital to install new source reduction equipment or implement new source reduction activities/initiat - Any additional increase to collection efficiency would require a plant-wide redesign that would cost prohibitive. |

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")
