Other Environmental Practices: Waste Treatment - Prior to 2021, the filter cake solid waste stream containing glycol ethers as well as other TRI and non-TRI chemicals was disposed of in a landfill. At the beginning of 2021, disposal of this waste stream was switched to a WTE facility which supplies the electric grid. The total amount landfilled was reduced from 191,000 lbs. in 2020 to 0 lbs. in 2021 and 2022, excluding a relatively small amount of residual ash. |

Other Environmental Practices: Energy Recovery - The solid waste stream containing 2,840 lbs. of glycol ethers as well as other TRI and non-TRI chemicals that was previously disposed of in a landfill has been switched so it is ultimately disposed of at a Covanta WTE facility. Although the disposal cost is approximately twice as much, this dramatically reduces the ultimate landfill amount (only small quantity of residual ash is landfilled), and the energy recovery is significant - the facility supplies the electric grid. Switching disposal of this combined waste stream from the landfill to the WTE facility has resulted in a reduction of approximately 200,000 lbs. landfilled in 2021. |

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")
