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: General Environmental Management - Enogen corn reduced our alpha requirements. More environmentally responsible because we dont have to ship a separate product or use plastic containers to hold it. Benefits include: Increase in yield, Reduction in energy costs, reducing gas, electricity and water consumption (This is a huge benefit for the environment), Less transportation time, due to the finished product coming from local suppliers. Usually within minutes of the plants. Shorter transportation time of a dry product, should have a reduced risk of spills vs a liquid product needing to be shipped OTR. The facility reevaluated many chemicals used when trying to align with FSMA and moved to GRAS chemicals. Aqueous Ammonia: Discontinued use due to stability of alpha enzyme activity in cook. New CO2 Scrubber Chemical: HydriMaize Inhibit used instead of ABS for HAPs & VOC control. Lowers incoming water usage to the scrubber. There was a 24% reduction in water usage to the CO2 Scrubber. Product also helps with reduction in potential sulfates in finished ethanol which also allowed us to reduce Hydrogen Peroxide in recycle water to cook. Fermentation Efficiency Project: Project consisted of reducing the fermenter cooler heat exchanger plates by 65%. Reduced fermenter pump motor from 350 hp to 150 hp motor. Completed on 7 fermenters. Replaced old lighting with new LED lighting in boiler house, process building and in the process of changing out lights in both DDEs. Using new strains of yeast in fermentation that are gluco amylase producing. Reduces liquid gluco amylase by 40%. 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 Low NOx burners in the Thermal Oxidizer systems were previously completed. This facility recycles solid wastes for all available products. 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 is available. We promote consistent waste management practices throughout our company. These efforts aid in reducing the amount of waste sent to landfills. Our goal is to reduce the amount of waste we send to landfills and increase the amount of materials recycled every year. 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 reduced emissions 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 be flared. By maintaining our emphasis on reliability, operational excellence and enhanced incident investigations, we will continue to target best-in-class environmental performance. |
