Waste Management Comparison - 2019
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:: S41: Improved scheduling, record keeping, or procedures for operations, cleaning, and maintenance
|
Methods to Identify SR Opportunities: T04: Participative team management
|
S41: Inventory and scheduling tracking |
| 2021 |
Source Reduction:: S35: Other improvements to inventory and material management[-5-14%]
|
Methods to Identify SR Opportunities: T04: Participative team management
Barriers: B1-Barriers to P2 B1 - Insufficient capital to install new source reduction equipment or implement new source reduction activities/initiat |
S35: Reduced order quantity and shared inventory across the division to limit scrapping materials due to expiring and exceeding retest specifications. Barriers to P2: B1 - Insufficient capital to install new source reduction equipment or implement new source reduction activities/initiat - Pandemic impact is still affecting aerospace and limiting capital for new equipment. |
| 2021 |
Source Reduction:: S25: Other process modifications made[-5-14%]
|
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 |
S25: Re-use third wash cleaning solvent in resin batch and minimize the amount of alcohol used in each cleaning cycle. Source Reduction - Identified through waste matrix and management implemented a green belt project to reduce the amount of alcohol used in the cleaning process. Barriers to P2: B1 - Insufficient capital to install new source reduction equipment or implement new source reduction activities/initiat - Pandemic reduced customer orders in the aerospace industry. |
| 2020 |
Other Barriers to Source Reduction - Pandemic caused major disruption with significant reduction in force. |

Source Reduction:: W67: Improved rinse equipment design
|
Methods to Identify SR Opportunities: T06: Employee recommendation (under a formal company program)
Barriers: B6-Barriers to P2 B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas |
W67: Solvent used to clean vat is heated and cascades down the side of the vat which removes more residue and decreases the amount of solvent required to clean by 35%. Source Reduction - Lean six sigma project Other Environmental Practices: Recycling - Starting September 2019 increased recycling of waste at off-site facility. Solvent used to clean vat has higher percentage solvent and is able to be recycled. Barriers to P2: B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas - Limited to specific chemical usage in drawings and specifications. |
| 2018 |
Barriers: B6-Barriers to P2 B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas
|
Barriers to P2: B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas - Reduced waste in prior years. Restricted to using specific product and cleaning with solvents is the only method to remove the adhesive resin from the print screens. |
|
| 2018 |
Other Barriers to Source Reduction - Customers require specific products designated on drawings. |
||
| 2017 |
Other Barriers to Source Reduction - Unable to substitute for a less hazardous chemical because raw material is hard called out on drawings by the customer. |
||
| 2017 |
Source Reduction:: W29: Other changes in inventory control[-0-4%]
Source Reduction:: W33: Installed overflow alarms or automatic shutoff valves[-0-4%] |
Methods to Identify SR Opportunities: T04: Participative team management
Methods to Identify SR Opportunities: T05: Employee recommendation (independent of a formal company program) Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s) |
W29: Kanban system of the AB2200Y to ensure product is produced just-in-time and will not exceed shelf-life prior to use. W33: Installed automatic shut-off valve to the solvent cleaning tank. Source Reduction - Leadership team championed process change of kanban system for AB2200Y to ensure using first-in and not manufacturing adhesive earlier than needed. Source Reduction - EHS audit of process. |
| 2016 |
Other Barriers to Source Reduction - Customer required products per drawings. |
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")
