  • 1. Global BioSciences, Inc. “ Sustainable technologies for a better environment ”
  • 2. Global BioSciences, Inc. Technologies Sold Exclusively Through Business Partners: • Environmental consulting, engineering and remediation firms • Business Partners receive generous margins • Several levels of partner participation & margin
  • 3. Business Partner Program • GBI leases hardware and technology to Authorized Business Partners (BPs) • BPs add value by providing marketing, sales, system design, project management, O&M • GBI provides technical support • In addition to margins BPs project referrals resulting from GBI marketing • The number of BPs and current discounts will be limited
  • 4. Pricing Alternatives • Panels provided exclusively on a lease basis • BPs provide air compressors, butane, nitrogen, Aquatane components, piping and installation • Technology lease fees • Monthly, fixed-fee or Pay-for- Performance pricing available
  • 5. Pilot Tests • Site-specific Pilot Tests recommended • GBI support provided • No technology lease fees for pilot tests or bench scale studies
  • 6. Patents 22 U.S. patents Many international patents* *Remediation patents in Europe, Eurasia, Mexico, Brazil, Canada, Australia, New Zealand and Japan.
  • 7. Global BioSciences (GBI) Technologies for: • Soil and groundwater remediation • Wastewater treatment • Odor Control • Plant growth, nitrogen fixation • Metal Recovery
  • 8. GBI Remediation Technologies Butane Biostimulation (BBT) – Butane Biosparging – Butane Bioventing – Butane Biopiles AquaTane – Low molecular weight hydrocarbon substrate designed for aerobic treatment
  • 9. GBI Remediation Technologies • Easy to implement • Low cost – Up to 60% less than alternatives • Field proven • No residual impacts
  • 10. Butane Biostimulation Technologies Treats many types of contaminants – Petroleum products (aromatics and PAHs) – Chlorinated solvents – PCBs – 1,4 - dioxane – Others Effective in soil and ground water
  • 11. Why Butane? • 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
  • 12. Why Butane? • 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
  • 13. Why Butane? • Butane-utilizing bacteria have been shown to fix nitrogen - able to produce their own nutrients • Ability to treat contaminants in either aerobic or anaerobic environments • Simple infrastructure – easy to switch rapidly from aerobic to anaerobic conditions at most sites • Degradation of CVOC daughter products occurs simultaneously
  • 14. BBT Currently Accepted* by...... US EPA Massachusetts - DEP Florida - DEP Maryland - MDE Pennsylvania - DEP Iowa - DNR CETESB – Brazil * never rejected
  • 15. Butane Breakdown Products CH3-CH2-CH2-CH3 (Butane) CH3-CH2-CH2-CH2-OH (1-Butanol) CH3CH2CH2CH=O (Butyraldehyde) CH3CH2CH2COO- (Butyrate) Further Metabolized
  • 16. TCA/TCE Degradation Pathway Using Butane 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
  • 17. MTBE Degradation Pathway Using Butane 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
  • 18. 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
  • 19. Injection Hardware is Simple, Safe And Code Compliant Single injection panel (6-14 wells) covers ~ 1-2 acre area Skid built into shed to provide comfortable work space for on-site workers
  • 20. 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 New Model Butane Injection System
