  1. Renewable Fuel in Iowa Innovation towards 2nd Generation January 28th 2014

  2. Introduction Iowa has an impressive record of supplying a significant portion of the nation’s fuel demands by building an infrastructure and supply chain in a relatively short period of time This infrastructure, coupled with a helpful legislative environment, makes Iowa a natural place for innovators to develop the next generation of biofuels.

  3. The Fiberight Story • Corn isn’t the only sugar source. • Anaerobic Digestion - Pathways • Hydrolysis - Pathways • Project Update

  4. Sugar from Trash

  5. MSW Composition

  6. Process Organic Pulp Alcohols Sugar Concentration & Refining Module Bio-Diesel Bio-Chemicals Process Bio-Plastics Rapid rate Digester & Gas Compression Core Intellectual Property CNG

  7. Organics rendered for processing

  8. 4,000 hrs Demonstration Completed Upstream processes separate soluble organics (for A/D), recyclables and contaminants, providing in a clean cellulose feedstock for enzymatic hydrolysis.

  9. Organic Pathways Organic Processes Anaerobic Digestion Cellulosic Hydrolysis High Solids A/D Low Solids A/D C5 & C6 Sugars Biogas & Compost Biogas & Bio-Products Biofuels & Biochemicals

  10. CBH II EG I, II BG R NR EG III CBH I Enzymatic Hydrolysis CBH: exocellobiohydrolase EG: endoglucanase BG: ß-glucosidase Provided the feedstock is optimized for the process, different enzyme systems hydrolyze the cellulosic structure and produce sugars.

  11. Recent Developments – High Yields Combining two developed processes has resulted in high conversion of cellulose to sugars at low enzyme dosing

  12. Anaerobic contact process Anaerobic pond Anaerobic filter (AF) Septic tank Upflow anaerobic sludge blanket (UASB) Imhoff tank Fluidized bed reactor Standard rate anaerobic digester Hybrid reactor: UASB/AF Anaerobic sequencing batch reactor (ASBR) Combining with A/D Innovation High-rate anaerobic reactors Low-rate anaerobic reactors Properly designed high-rate anaerobic digesters can increase COD conversion by 50%, whilst reducing dwell time by a factor of 50.

  13. Biogas Heater Effluent Perforated Al plate Sampling port Water bath Peristaltic pump Media Sludge wastage Constant temperature recirculation line Feeding Tank Peristaltic pump Typical Low Solids A/D Methanogenic Colony remains in digester reactor, with significantly higher surface area contact. Key is to manage TSS.

  14. Fiberight Low Solids A/D plant Fiberight’s proprietary processes recover over 90% of COD, via anaerobic digestion, in less than 8 hours Experienced up to 26 kg COD destruction per M3 reactor/day

  15. Integrated Process Pathway Processed Biomass Anaerobic Digestion Cellulosic Hydrolysis Low Solids A/D C5 & C6 Sugars Biogas & Bio-Products Energy Generation Biofuels & Biochemicals

  16. Part of an integrated solution Low solids A/D and cellulose hydrolysis is only feasible when integrated with upstream processing. Organic rich streams are processed via high solids pulping to create a biomass for further upgrading.

  17. Project Status

  18. Marion Waste Recovery Facility • 15 Year agreement signed in August 213, construction starting early summer 2014 – Operational Q4 2014.

  19. Blairstown Biorefinery • Plant conversion commenced Q3 2013, New building addition commencing when ground not frozen!!!!. Equipment install slated for July 2014.

  20. Turning trash into finished biofuel…a disruptive and transformational clean technology Craig Stuart-Paul – CEO With Thanks to Dr. Stephanie Lansing, University of MD craigsp@fiberight.com
