GBI Remediation TechnologiesButane Biostimulation (BBT)
– Butane Biosparging– Butane Bioventing– Butane Biopiles
AquaTane– Low molecular weight hydrocarbon
substrate designed for aerobic treatment
![Page 9: GBI Remediation Presentation](https://reader034.vdocuments.site/reader034/viewer/2022042518/54c09cea4a79594b538b45c2/html5/thumbnails/9.jpg)
GBI Remediation Technologies
• Easy to implement• Low cost
– Up to 60% less than alternatives• Field proven• No residual impacts
![Page 10: GBI Remediation Presentation](https://reader034.vdocuments.site/reader034/viewer/2022042518/54c09cea4a79594b538b45c2/html5/thumbnails/10.jpg)
Butane Biostimulation TechnologiesTreats many types of contaminants
– Petroleum products(aromatics and PAHs)
– Chlorinated solvents– PCBs– 1,4 - dioxane– Others
Effective in soil and ground water
![Page 11: GBI Remediation Presentation](https://reader034.vdocuments.site/reader034/viewer/2022042518/54c09cea4a79594b538b45c2/html5/thumbnails/11.jpg)
WhyButane?• Butane gas provides a sustainable carbon source to stimulate
the growth of indigenous microbial communities
• Many forms of bacteria exhibit accelerated growth under butane stimulation
• Butane-grown bacteria also produce enzymes that rapidly degrade toxic chemicals
• Butane is the heaviest and most soluble of the alkane gases(propane, methane) – important for bioavailability
![Page 12: GBI Remediation Presentation](https://reader034.vdocuments.site/reader034/viewer/2022042518/54c09cea4a79594b538b45c2/html5/thumbnails/12.jpg)
WhyButane?• As a gas, butane disperses and diffuses rapidly and broadly
in the subsurface – large radius of influence
• Gaseous nature makes butane uniquely suited to remediation in low-permeability environments
• Contaminated soil in the unsaturated zone and capillary fringe also treated
• Easily adaptable to biopiles
![Page 13: GBI Remediation Presentation](https://reader034.vdocuments.site/reader034/viewer/2022042518/54c09cea4a79594b538b45c2/html5/thumbnails/13.jpg)
WhyButane?• Butane-utilizing bacteria have been shown to fix nitrogen -
able to produce their own nutrients
• Ability to treat contaminants in either aerobic or anaerobicenvironments
• Simple infrastructure – easy to switch rapidly from aerobic to anaerobic conditions at most sites
• Degradation of CVOC daughter products occurs simultaneously

TCA/TCE Degradation Pathway UsingButane Remediation
Chlorinated Ethenes (TCE Epoxidation)
CHCl=CCl2 + H2O = CHClOCCl2 + 2H+ + 2e-
Chlorinated Ethanes (1,1,1-TCA Hydroxylation)
CH3CCl3 (TCA) + H2O = CH3CCl2OH +2H+ + 2e-
Final products CO2, H2O, and chloride ions
![Page 17: GBI Remediation Presentation](https://reader034.vdocuments.site/reader034/viewer/2022042518/54c09cea4a79594b538b45c2/html5/thumbnails/17.jpg)
MTBE Degradation Pathway UsingButane Remediation
• MTBE = (CH3)3COCH3 / C5H12O
• Enzymes accelerate C5H12O Demethylation
• MTBE degraded to form tert-butyl alcohol (TBA) and formaldehyde
• These species quickly decompose into H2O and CO2
![Page 18: GBI Remediation Presentation](https://reader034.vdocuments.site/reader034/viewer/2022042518/54c09cea4a79594b538b45c2/html5/thumbnails/18.jpg)
Butane Safety• Non-Toxic – Used in food processing
• Safe, UL engineered panel
• Concentrations generated in the subsurface with the butane injector are less than 0.01% of the LEL for butane in air
• Excess butane in soil/groundwater decomposes into CO2, H2O, and other inert species in 2-3 days
![Page 19: GBI Remediation Presentation](https://reader034.vdocuments.site/reader034/viewer/2022042518/54c09cea4a79594b538b45c2/html5/thumbnails/19.jpg)
