CAMBRIDGE, Mass. — GreenFuel Technologies Corp., a private company developing algae farming technologies for recycling carbon dioxide emissions, has recruited Simon Upfill-Brown to be chief executive officer (CEO), and the former Dow Chemical executive was elected to GreenFuel’s board of directors.

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.

After graduating in 1975 with degrees in chemistry and mathematical statistics from South Africa’s Stellenbosch University, Upfill-Brown started his career as a bench chemist. He moved into sales, marketing and, eventually, general management in the chemicals industry. He received his MBA from Stanford in 1985.

Upfill-Brown replaces Bob Metcalfe, who was interim CEO of GreenFuel since June 2007. Metcalfe is a general partner of Polaris Venture Partners, a lead investor in GreenFuel along with Access Private Equity and Draper Fisher Jurvetson, who completed a $13.9 million venture financing for GreenFuel last month. On the board, he will join Chairman Jennifer Fonstad of DFJ, Peter Thoren of Access, Metcalfe, Cary Bullock (former GreenFuel CEO and current VP Business Development) and Columbia University Professor Gordana Vunjak-Novakovic.

GreenFuel is developing high-yield algae farm technologies to profitably recycle industrial carbon dioxide and produce feed, food and fuel ingredients. GreenFuel has had successful pilot installations of its technology at host facilities in Arizona, Kansas, Louisiana, Massachusetts, New Mexico and New York.
