 Profile

John P. Chastain has been a faculty member at Clemson University since August 1995. where his extension and research responsibilities include: animal waste collection and storage systems, land application of animal wastes and municipal sludge, alternative uses of waste, bioenergy from waste, odor control from animal production units, planning of animal production systems to protect surface and ground water quality, improving energy efficiency, use of alternative energy, and general livestock facility design.

Prior to joining the faculty at Clemson University, he was on faculty at the University of Minnesota for 3.5 years where his responsibilities included dairy housing facilities and manure management. He has also been involved in international agricultural development projects in Tanzania, and Uganda, East Africa.
