Global BioSciences (GBI) Technologies for:
• Soil and groundwater remediation• Wastewater treatment• Odor Control• Plant growth, nitrogen fixation• Metal Recovery
GBI Remediation TechnologiesButane Biostimulation (BBT)
– Butane Biosparging– Butane Bioventing– Butane Biopiles
AquaTane– Low molecular weight hydrocarbon
substrate designed for aerobic treatment
GBI Remediation Technologies
• Easy to implement• Low cost
– Up to 60% less than alternatives• Field proven• No residual impacts
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
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
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
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
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
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
Injection Hardware is Simple, SafeAnd Code Compliant
Skid built into shed to provide comfortable work space for on-site workers
Single injection panel (6-14 wells) covers ~ 1-2 acre area
Butane Injection System
• Modular panel cost effective at larger Sites
• Controlled & monitored remotely via Internet, cellular or radio communication
• Turn Key (shipped via UPS)
• Rugged & compact

Note: Activated carbon has been removed from process stream – large cost savings to client
