Improving Biogas Purification: A Renewable Energy Application for the University of Maryland


Gemstone Team



On a campus that serves over 40,000 people daily, waste disposal poses both environmental and logistical concerns.  In an effort to reduce campus food waste, students and staff have turned to composting.  However, the composting process produces biogas containing methane, a greenhouse gas that is 20 times more potent than carbon dioxide.  Through a proposed purification process, this biogas can be utilized by the university to further increase energy efficiency and decrease harmful emissions.

This Gemstone team hypothesizes that a biogas purification system will clean biogas in a safer and more cost-efficient way than chemical purification.  Thus, the system will not only benefit the environment and decrease costs but also spread awareness of the potential of biogas as a viable energy source.
