Cobalt Technologies and American Process have signed an agreement to build an industrial-scale cellulosic biorefinery to produce biobutanol.

Under the agreement, the companies will integrate Cobalt’s continuous fermentation and distillation technology into American Process’s Alpena Biorefinery in Michigan,US.

Alpena Biorefinery is currently under construction is slated to begin ethanol production in early 2012 with a switch to biobutanol in mid 2012.

Alpena Biorefinery is expected to produce 470,000 gallons of biobutanol annually, which will be pre-sold to chemical industry partners.

The companies also agreed to jointly market a GreenPower Biobutanol solution to biomass power facilities and other customers globally.

GreenPower Biobutanol technology selectively converts part of a boiler cellulosic biomass feedstock into renewable biobutanol.

Cobalt is engaged in commercializing biobutanol as a renewable chemical and fuel.

American Process is engaged in development and commercialization of lignocellulosic sugar production and bioenergy process technologies.
