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 |
Other Environmental Practices: Recycling - Methanol is produced as a grain fermentation impurity. Exhaust gas from grain fermenters is treated by a wet scrubber before being exhausted to the atmosphere. The scrubber water containing recovered organics in the exhaust gas is further processed for water removal and organics recovery as product. This has been determined to qualify as "recycling". |

Barriers: B7-No Information B7 - No known substitutes or alternative technologies.

| 2017 |
Barriers: B3-Barriers to P2 B3 - Concern that product quality may decline as a result of source reduction.
|
Other Environmental Practices: Recycling - The amount recycled is the difference between the amount produced and the amount released to the environment. This is likely an overestimate regarding the quantity recycled. Barriers to P2: B3 - Concern that product quality may decline as a result of source reduction. - Production of this chemical is directly related to total ethanol production. |

Barriers: B3-Barriers to P2 B3 - Concern that product quality may decline as a result of source reduction.

Other Environmental Practices: Recycling - The facility has amended calculation methods to include total chemical recycled. The amount recycled is the difference between the amount produced and the amount released to the environment. This is likely an overestimate regarding the quantity recycled. Other Environmental Practices: Waste Treatment - The facility has amended calculation methods to include total chemical treated. Barriers to P2: B3 - Concern that product quality may decline as a result of source reduction. - Production of this chemical is directly related to total ethanol production. |

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")
