SunEthanol, a cellulosic biofuels company, has appointed William Frey as its new CEO.

Mr Frey will replace Jef Sharp, who has led the company since its founding in 2006. Previously, Mr Frey led the efforts to commercialize advanced biofuels and new cellulosic process technologies being developed by DuPont.

Mr Frey has led the team that developed DuPont Biofuels as a business unit in 2002, and has broad partnership experience with industry majors such as BP, British Sugar, Tate & Lyle and Genencor, a division of Dansico, as well as significant experience in working with global government agencies.

Mr Frey said: SunEthanol’s C3 process holds great promise because of the robustness of the Q-Microbe and its ability to convert a wide variety of feedstocks into clean, usable ethanol. I look forward to making SunEthanol a world leader in the race to displace gasoline with home-grown biofuels.
