Waste Management Comparison - 2020
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:: S21: Optimized process conditions to increase efficiency[-5-14%]
|
Methods to Identify SR Opportunities: T11: Other
|
Source Reduction - Improvement of scheduling to reduce amount of purge solvent used Other Environmental Practices: Recycling - Purge solvent recovered and sent for recycling. Which is then brought back to facility to be used again. |
| 2021 |
Source Reduction:: S25: Other process modifications made
|
Methods to Identify SR Opportunities: T11: Other
|
S25: Change in production load for a specific painting operation has reduced onsite emission Source Reduction - Reduction in production load for specific operation |
| 2020 |
Source Reduction:: W42: Substituted raw materials[-5-14%]
|
Methods to Identify SR Opportunities: T10: Vendor assistance
|
W42: Reduce/replace 1,2,4 trimethylbenzene in purge solvent and coatings, with a better environmental option |
| 2019 |
Source Reduction:: W14: Changed production schedule to minimize equipment and feedstock changeovers[-0-4%]
|
Methods to Identify SR Opportunities: T04: Participative team management
|
W14: Continue to alter production schedule to reduce changeovers. Other Environmental Practices: Recycling - Purge Solvent used to clean painting equipment is captured and sent to be recycled. After recycled it is brought back to the facility and used again. This reduces the need for virgin material. |
| 2018 |
Source Reduction:: W14: Changed production schedule to minimize equipment and feedstock changeovers[-0-4%]
|
Methods to Identify SR Opportunities: T04: Participative team management

Source Reduction:: W72: Modified spray systems or equipment |
Methods to Identify SR Opportunities: T04: Participative team management
Methods to Identify SR Opportunities: T04: Participative team management |
W49: chemical mixture of purge solvent adjusted/changed W72: Low volume paints placed on pigable systems. This will require less purge solvent when changing paints Source Reduction - Best practice |
| 2015 |

TRI Pollution Prevention Glossary
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")
