Pollution Prevention Activities for Selected Chemical

Reporting Year	Section 8.10: Methods to Identify Activity	Section 8.11: Optional Pollution Prevention Information*
2020	Barriers: B8-Barriers to P2 B8 - A reduction does not appear to be technically feasible	Barriers to P2: B8 - A reduction does not appear to be technically feasible - Ammonia is used for pH adjustment and as a feedstock for yeast. Control is based on consumption within the process. Further, the process uses an additional nitrogen feedstock, urea, for yeast since anhydrous ammonia addition alone is not enough to support fermentation. The facility also uses Ammonia salts as an additive in the fermentation scrubber as VOC and HAP control. As such, source reduction is not technically feasible at this time.
2019	Barriers: B8-Barriers to P2 B8 - A reduction does not appear to be technically feasible	Barriers to P2: B8 - A reduction does not appear to be technically feasible - Ammonia is used for pH adjustment and as a feedstock for yeast. Control is based on consumption within the process. Further, the process uses an additional nitrogen feedstock, urea, for yeast since anhydrous ammonia addition alone is not enough to support fermentation.
2018	Barriers: B8-Barriers to P2 B8 - A reduction does not appear to be technically feasible	Barriers to P2: B8 - A reduction does not appear to be technically feasible - Ammonia is used for pH adjustment and as a feedstock for yeast. Control is based on consumption within the process. Further, the process uses an additional nitrogen feedstock, urea, for yeast since anhydrous ammonia addition alone is not enough to support fermentation.
2017		Other Barriers to Source Reduction - Ammonia is used for pH adjustment and as a feedstock for yeast. Control is based on consumption within the process. Further, the process uses an additional nitrogen feedstock, urea, for yeast since anhydrous ammonia addition alone is not enough to support fermentation.
2016		Other Barriers to Source Reduction - Ammonia is used for pH adjustment and as a feedstock for yeast. Control is based on consumption within the process. Further, the process uses an additional nitrogen feedstock, urea, for yeast since anhydrous ammonia addition alone is not enough to support fermentation. Other Environmental Practices: Waste Treatment - The facility has amended calculation methods to include total chemical treated. Control is based on consumption within the process.

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.
