Catawba College Sustainability Department Greenhouse build

Twin Dragons of Catawba

Working with fellow National Geographic Explorer Dr. Luke Dollar, Chair of the Center for the Environment and Catawba College's Department of Environment and Sustainability and his students, T.H. and Enas Culhane built a "twin dragon" Solar CITIES IBC tank digester system with floating IBC tank gas holder inside the greenhouse on campus. The system has 100 foot of pex coil in each tank connected to a propane gas water heater to circulate hot water in the system and will eventually be switched to biogas.
