CFAES’s Thaddeus “Teddy” Ezeji speaks on “Butanol Production from Lignocellulosic Biomass: Challenges and Opportunities” at 3 p.m. on Thursday, Oct. 2, in 081 Halterman Hall at the Ohio State University Agricultural Technical Institute, 1328 Dover Road, in Wooster. Ezeji is an associate professor in the Department of Animal Sciences. Butanol, which can be used in place of gasoline as fuel in car engines, can be made from plant-based biomass. A 2013 story in Fortune called it “The fuel that could be the end of ethanol.” ATI is CFAES’s two-year degree-granting unit. Among its majors is an associate of science degree in renewable energy.
