Qi BioEnergy

SunEthanol’s bio-processing technology is based upon a remarkable proprietary microbial “catalyst” that is uniquely capable of efficiently converting a wide range of cellulosic biomass directly to ethanol. By simplifying and consolidating the costliest aspects of current biomass-to-ethanol technology, SunEthanol can reduce both process and plant capital costs, making large-scale ethanol production from cellulosic biomass cost-effective.

A more economical process

Converting cellulose to ethanol is currently a complex, multi-step process. Cellulosic biomass - plant matter - is an abundant, low-cost source of stored energy. However, unlocking that embodied energy has presented a challenge. Cellulosic biomass is composed of highly ordered sugar polymers, which are shielded from enzyme attack by a matrix of other complex polymers. This makes biomass very difficult to break down into its constituent sugars, in order to ferment these sugars into ethanol.

Typically, cellulosic biomass must go through an intensive pretreatment step, after which enzymes are used to break down the biomass into simple sugars suitable for fermentation by yeast into ethanol. Enzymes, along with the intensive pretreatment required for their use, are the largest single cost component of cellulosic ethanol production. SunEthanol’s technology eliminates the need for a separate enzymatic conversion step, and broadens pretreatment options.
