Renewable Fuel in Iowa

Innovation towards 2nd Generation

January 28th 2014

introduction
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.

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.

Recent Developments – High Yields

Combining two developed processes has resulted in high conversion of cellulose to sugars at low enzyme dosing

Typical Low Solids A/D

Methanogenic Colony remains in digester reactor, with significantly higher surface area contact. Key is to manage TSS.

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.
