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:: S21: Optimized process conditions to increase efficiency[-0-4%]	Methods to Identify SR Opportunities: T04: Participative team management	S21: Since silver is the product we sell, we do not measure overall volume of silver manufactured or processed, but pounds of scrap created per pound of product manufactured. We work to increased efficiency regularly. For silver, we began migrating silver products from an older sieve to a new, upgraded sieve that has a higher efficiency and lower scrap rate.
2019	Source Reduction:: W89: Other product modifications[-0-4%]	Methods to Identify SR Opportunities: T04: Participative team management Methods to Identify SR Opportunities: T03: Materials balance audits	Source Reduction - Management team focus on COGS
2018	Source Reduction:: W29: Other changes in inventory control[-5-14%] Source Reduction:: W52: Modified equipment, layout, or piping[-0-4%] Source Reduction:: W58: Other process modifications[-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: T06: Employee recommendation (under a formal company program) Methods to Identify SR Opportunities: T04: Participative team management	W29: Relocated processing of some products to our sister plant in Port Huron Michigan where they have space for more efficient equipment to reduce silver byproduct. W52: Installed a tray dumper on a sieve that processes silver. This increases capture efficiency of the airborne silver particulate, which captures it for recycling W58: Modernization of sieving equipment to increase efficiency and reduce scrap material. This improves yields. Source Reduction - TUR submission program Source Reduction - TURA Team Meeting idea to increase silver yields
2017	Source Reduction:: W49: Other raw material modifications[-0-4%] Source Reduction:: W50: Optimized reaction conditions or otherwise increased efficiency of synthesis[-0-4%]	Methods to Identify SR Opportunities: T05: Employee recommendation (independent of a formal company program) Methods to Identify SR Opportunities: T04: Participative team management Methods to Identify SR Opportunities: T04: Participative team management Methods to Identify SR Opportunities: T11: Other	W49: Implemented better process control procedures for ammonia recycling unit to provide better quality input material for product, resulting in reduced waste or scrap product. W50: Increase yields by adjusting reaction times, temperatures, and chemical volumes Source Reduction - Toxic Use Reduction Team Source Reduction - Quality Control Team Source Reduction - Process Engineer Suggestion
2015	Source Reduction:: W50: Optimized reaction conditions or otherwise increased efficiency of synthesis[-15-24%]	Methods to Identify SR Opportunities: T04: Participative team management	W50: Increase yields of silver powder using quality control technology, include chemical reactant flow control
2013	Source Reduction:: W15: Introduced an in-line product quality monitoring or other process analysis system	Methods to Identify SR Opportunities: T11: Other	Source Reduction - Quality systems in place that reduce the amount of re-work material. 30% decrease to off site locations

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.

Source Reduction includes activities that eliminate or reduce the generation of chemical waste.
Recycling includes the recovery of a toxic chemical in waste for reuse.
Energy Recovery includes the combustion of toxic chemicals in waste to generate heat or electricity.
Treatment includes the destruction of a toxic chemical in waste.
Disposal or Other Releases includes toxic chemical quantities entering the environment.

The PPA requires facilities to provide the following details about each chemical they report to TRI:

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")

Facilities may also provide optional Pollution Prevention Information describing their source reduction, recycling, or pollution control activities.
