Other Environmental Practices: Recycling - During 2022, Lubrizol's Louisville Plant implemented 6 separate projects that saved and will continue saving a total of 24.4 million gallons of water, annually. One of those projects won the Waste Minimization, Reuse and Recycling Award in the American Chemistry Council's Responsible Care awards program. Lubrizol was recognized for its Centrate Recycle project at its Louisville, Kentucky, plant. The goal was to reduce water and steam consumption and to decrease the volume of water sent to the local publicly owned treatment works (POTW), through recycling materials in new ways. This enabled the plant to replace 50% of the hot water it used in a process and to eliminate the steam addition needed, saving 11.5 million gallons of water, 3.2 million pounds of steam and more than 240 tons of CO2 emissions annually. Other Environmental Practices: Energy Recovery - During 2022, Lubrizol's Louisville Plant implemented 10 separate projects that saved and will continue saving a total of 0.83 million KWh of electricity and 6.86 million lbs. of steam, annually. |

W39: Added interlock to stop monomer day tanks from refilling if they are not being fed to any premix system, reduces risk of monomer building up in recovery system through an open valve. W52: Electropolished thermowells to smooth the surface and prevent product build up that would become waste. W58: 1) Automated loading of stripping recipes, which reduces risk of entering any incorrect setpoints and lowers the chance of exposing high residual monomer batches to the atmosphere. 2) Changed DCS conditions to reduce likelihood of contamination from backflow. |

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")
