The Bio-Environmental Design Team at The Ohio State University (OSU) will collaborate with the Department of Food, Agricultural and Biological Engineering (FABE) Undergraduate Senior Capstone Design Course to design, build, and test a bench scale renewable electrical energy generation system employing a microbiological fuel cell to utilize dairy waste as a feedstock. The OSU Waterman Dairy Farm will provide necessary waste products. This microbiological fuel cell system will be scaled up for pilot testing based on experimental bench results, time, and resources available.
The immediate project goals will be to build an anaerobic digester designed to oxidize dairy waste and produce electricity using the microorganisms Geobacter sulfurreducens or Rhodoferax ferrireducens. The feedstock will be composed of bovine urine, manure, and wash water. The P3 award will be integrated into an entire year of the participating students curricula either by being directly enrolled in the Capstone Design Course, or by being a member of the extracurricular Bio-Environmental Design Team. Students in the Capstone Design Course perform research, propose designs, conduct testing, develop plans and procedures, and build a prototype in an effort to solve a given problem. The Bio-Environmental Design Team has developed prototypes of the microbiological fuel cell, and was competitively selected to present their preliminary results at the national meeting of the American Society of Agricultural Engineers in August 2004. Leaders of the Design Team will become peer mentors and project supervisors for the Capstone Design Course. The FABE department provides a unique environment for this project by embodying the principles of interdisciplinary learning and the integration of economically viable, socially beneficial, and environmentally sound engineering principles with undergraduate education. By teaming with the Department of Microbiology and the School of Natural Resources, the students will gain a rich interdisciplinary experience.
The overarching project objectives will be to decrease farm dependence on fossil fuel generated electricity, decrease environmental impact of the farm, turn a waste stream from an economic cost into a gain, and provide benefit to the surrounding community.
