CAMBRIDGE, Mass.--GreenFuel Technologies Corporation, a private company developing algae farming technologies for recycling CO2 emissions, has recruited Simon Upfill-Brown to be Chief Executive Officer (CEO), starting July 14. The former Dow Chemical executive will also be elected to GreenFuel’s Board of Directors on July 23. Upfill-Brown comes to GreenFuel from Haltermann Custom Processing, of which he was CEO starting in 1993. After Dow Chemical bought the $50 million Houston company in 2001, he was General Manager of Dow Haltermann until it was spun out in 2008 with international operations employing 435 people and earning $230 million in annual revenues. Haltermann provides specialty chemical manufacturing services, including biodiesel, for which GreenFuel plans to be an algae oil feedstock supplier. Link.
