| 2016 |
Source Reduction:: W50: Optimized reaction conditions or otherwise increased efficiency of synthesis
|
Methods to Identify SR Opportunities: T04: Participative team management
|
W50: Improved utilization of manganese recovery process by implementing piping and control changes. Source Reduction - After opportunity was realized, the plant team began the planning and implementation of improvement the last quarter of CY16. |
| 2015 |
Source Reduction:: W52: Modified equipment, layout, or piping[-0-4%]
|
Methods to Identify SR Opportunities: T06: Employee recommendation (under a formal company program)
|
W52: Energizer plans to modify piping in our leach process to improve manganese recovery. |
| 2014 |
Source Reduction:: W52: Modified equipment, layout, or piping

| 2013 |
Source Reduction:: W52: Modified equipment, layout, or piping
|
Methods to Identify SR Opportunities: T11: Other
|
W52: Added dust collection to calcined ore unloading station. Source Reduction - Added dust collection at calcined ore unloading station. The driver was to reduce colleague exposure to manganese dust; however, it also reduced dusting to environment. Source Reduction - Energizer Marietta will be installing additional dust collection on calcined ore storage bins to reduce risk of dusting in 2014. |
| 2012 |
Source Reduction:: W51: Instituted recirculation within a process
|
Methods to Identify SR Opportunities: T01: Internal pollution prevention opportunity audit(s)
|
Source Reduction - Equipment and control upgrades have made manganese recovery process more reliable during CY!2; thus, the plant realized a reduction in Manganese losses. |

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")
