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*
2019 Barriers: B6-Barriers to P2 B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas
Barriers: B5-Barriers to P2 B5 - Specific regulatory/permit burdens.

Other Environmental Practices: Recycling - Improving recycling efforts: Our facility operations mostly generates non-hazardous solid waste consisting of paper, plastics,scrap metals, used oils, food wastes and wooden pallets. All those generated wastes were recycled where such service isavailable. We promote consistent waste management practices throughout our company. These efforts aid in reducing theamount of waste sent to landfills. Our goal is to reduce the amount of waste we send to landfills and increase the amount ofmaterials recycled every year. COD recycling program in lab show reduction of hazardous waste

Barriers to P2: B5 - Specific regulatory/permit burdens. - Ethanol production is regulated by TTB and EPA and specifications for fuel grade ethanol are regulated by both agencies.

Barriers to P2: B6 - Pollution prevention previously implemented - additional reduction does not appear technically or economically feas - This facility already installed and utilizes BACT/MACT technology across its emission control systems. Upgrades to Ultra LowNOx burners in the Thermal Oxidizer systems were previously completed. This facility recycles solid wastes for all availableproducts. This facility maintains healthy and active wetlands to support wildlife conservation.

Other Environmental Practices: General Environmental Management - The facility reevaluated many chemicals used when trying to align with FSMA and moved to GRAS chemicals. Mount Vernonethanol facility maintain healthy and active wetlands to support wildlife conservation. They have planted over 500 additional treesin 2018. Light Bulb conversion to LED to lower cost, efficient, Safer. Waste Heat Recovery, Dryer 1 process stream recoverysavings on gas consumption. Reuse of waste water aerobics system in place of discharging process water.

Source Reduction: Methods for Identifying Pollution Prevention Opportunities - Green Plains intends to continue to reduce its greenhouse-gas and other air emissions through adoption of new technologies,improved and more efficient operations for several years. Green plains had always maintained BACT and MACT guidance/standard mandate for air pollution control. We additionally have spent millions of dollars on environmental upgrades to reducedemissions and improved the environment. These include flue-gas scrubbers that dramatically slash emissions of sulfur dioxide,nitrogen oxide and particulate matter, and flare-gas recovery systems that capture and recycle gases that otherwise would beflared. By maintaining our emphasis on reliability, operational excellence and enhanced incident investigations, we will continueto target best-in-class environmental performance.

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