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 | |||
| 2021 |
Other Environmental Practices: Energy Recovery - Heater "A" uses the facility's recycle material, which includes both styrene and ethylbenzene, as its fuel source. This reduces the overall usage of natural gas. |
||
| 2020 |
Other Environmental Practices: Energy Recovery - Recycle material is used in the facility's Heater A as noted in Section 8.10. The ability to use styrene/ethyl benzene as an alternative fuel source also reduced the amount of natural gas utilized at the heater. 2020 was a planned process shutdowns, expecting less recycle fuel used in 2021. |
||
| 2019 |
Source Reduction:: W19: Other changes in operating practices[-5-14%]
|
Methods to Identify SR Opportunities: T04: Participative team management
|
W19: Improved recycle management, returning used process material back to reactor at the appropriate levels. T04 Team effort, Used R5 <15% the amount reduce in heater usage. Other Environmental Practices: Energy Recovery - Recycle material is used in the facility's Heater A as noted in Section 8.10. The ability to use styrene/ethyl benzene as an alternative fuel source also reduced the amount of natural gas utilized at the heater. 2020 is planned process shutdowns, expecting less recycle fuel. Source Reduction: Source Reduction - RCRA Part B permit issuance allowed ability to increase alternative fuel usage. Utilize Heater A waste fuel which uses facility's recycle material (Styrene /ethyl benzene) as the fuel source. More recycle used in the heater means less hazardous waste generated for off-site management. |
| 2018 |
Source Reduction:: W58: Other process modifications
|
Methods to Identify SR Opportunities: T11: Other
|
W58: Utilize Heater "A" waste fuel which uses facility's recycle material (Styrene /ethyl benzene) as the fuel source. More recycle used in the heater means less hazardous waste generated for off-site management. Source Reduction - RCRA Part B permit issuance allowed ability to increase alternative fuel usage. Other Environmental Practices: Energy Recovery - Recycle material is used in the facility's Heater A as noted in Section 8.10. The increase in the ability to use styrene/ethyl benzene as an alternative fuel source also reduced the amount of natural gas utilized at the heater. |
| 2017 |
Other Environmental Practices: Energy Recovery - Increased fuel usage in hazardous waste BIF beginning in 2018. Issuance of RCRA Permit B permit allows for an increased feed rate limit. |
||
| 2016 |
Other Environmental Practices: Energy Recovery - A hazardous waste combustor is used on site to burn waste fuel for energy. The facility would be able to burn more waste in the combustor if the agency granted the facility the ability to store and burn waste more than 50% level in the storage tank currently allowed. |
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")
