Anaerobic digestion

Anaerobic digesters use animal, human or plant waste materials to create renewable energy (methane ‘biogas’) and an improved fertilizer while reducing water pollution, greenhouse gas emissions, and odor. My research focuses on the development of low-cost digestion systems that can be used by small to medium-scale farmers both in the United States and the developing world. My current digestion research sites include dairy and poultry agricultural digesters in Maryland, dairy and swine agricultural digesters in Costa Rica, human waste digesters in Haiti, palm oil effluent digesters in Sierra Leone, and anaerobic digesters coupled with microbial fuel cells for use in developing countries.
