Dr. Butler’s research focus on developing energy-efficient treatment strategies for both water and wastewater treatment through the study of biofilm systems. She is interested in developing scalable process designs that could be easily integrated into existing treatment infrastructure and the ecology and function of the microorganisms that facilitate treatment.
An example includes, the Microbial Fuel Cell Latrine that directly converts human waste into electricity. Built with community resources, our Microbial Fuel Cell Latrine is a low-cost, low maintenance toilet that reduces disease, helps preserve the environment, enhances human dignity, provides incentives through the generation of electric light and compost, and meets the decentralized sanitation needs of rural communities in developing countries.[
