"ZeaChem appreciates the new investment from Birchmere Ventures and the continuing support and confidence from our existing investors as we commercialise our highly efficient, economical and flexible biorefinery technology," Jim Imbler, President and CEO of ZeaChem says.

ZeaChem's 250,000 GPY integrated demonstration biorefinery in Boardman, Oregon, will come online in 2011. The company is now developing commercial biorefineries for the production of advanced biofuels and bio-based chemicals.

The financing round was led by Birchmere Ventures. Follow on investment was provided by existing investors Firelake Capital, Globespan Capital Partners, Mohr Davidow Ventures, PrairieGold Venture Partners and Spring Ventures.
