Renewable Fuel in Iowa
Innovation towards 2nd Generation
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.

Provided the feedstock is optimized for the process, different enzyme systems hydrolyze the cellulosic structure and produce sugars.
Recent Developments – High Yields
Combining two developed processes has resulted in
high conversion of cellulose to sugars at low
enzyme dosing
Combining with A/D Innovation
Low-rate anaerobic reactors High-rate anaerobic reactors
Anaerobic pond
Septic tank
Standard rate anaerobic digester
Imhoff tank
Anaerobic sequencing batchreactor (ASBR)
Anaerobic contact process
Anaerobic filter (AF)
Upflow anaerobic sludge blanket (UASB)
Fluidized bed reactor
Hybrid reactor: UASB/AF
Properly designed high-rate anaerobic digesters can increase COD conversion by 50%, whilst reducing dwell time by a factor of 50.

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

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.
Project Status
Marion Waste Recovery Facility
15 Year agreement signed in August 213, construction starting early summer 2014 – Operational Q4 2014.
Blairstown Biorefinery
Plant conversion commenced Q3 2013, New building addition commencing when ground not frozen!!!!. Equipment install
slated for July 2014.
