Innovation application: Biofuel Production Technology from Biomass

Title Biofuel Production Technology from Biomass

Demand for renewable fuels is growing. However the major restraining factors of biofuel production are associated with the high costs of the substrate and production process. The proposed technology offers environmentally friendly production of a second generation biofuels from lignocellulosic biomass not intended for human consumption (agricultural waste, weeds, straw, wood-processing waste). The technology is applicable to production of both bio-ethanol or bio-butanol.

Description of the technology

The technology consists of simple mechanical pre-treatment that is combined with brief boiling and enzymatic hydrolysis.

Fermentation feed separation and enzyme recirculation is provided via specific membrane separation technologies to decrease the production costs, remove fermentation inhibitors and balance hydrolysis with fermentation.

Applications The technology is applicable to both large and small scale production systems (local farms, food processing companies) and can be introduced as a secondary unit within other bioenergy production systems, e.g., biogas plants.

The production of biofuel does not involve hazardous or eco-unfriendly lignocellulosic biomass treatment techniques, e.g., acid or base hydrolysis, steam explosion. For enzymatic hydrolysis it is possible to apply commercially available or special in-house made enzymes. Production costs are reduced with the introduction of membrane separation techniques. The technology is applicable to production of both bio-ethanol or bio-butanol.
