Craig Frear is Director of Research and Technology at Regenis, America’s premier anaerobic digester construction company. Previously with Washington State University (WSU), he was instrumental in developing one of the nation’s most prolific applied science and engineering programs in organic residuals and animal manure treatment for sustainable reuse.


Over the last decade, Craig’s research has focused on enhancements to anaerobic digestion, biochemical recovery from waste and development of bio-refinery principles for rural and urban communities. He holds five patents (with two pending) including an ammonia stripping system to remove ammonia from wastewater without the use of chemicals. In addition to his research, Craig is the author of more than sixty peer-reviewed publications on methane capture to create biogas and nutrient management to allow liquid from manure to be safely reused. He has also served as an investigator on numerous federal and state grants in the same scientific classifications.


Craig holds a Ph.D. in Engineering Science from Washington State University, a master’s in Educational Administration from Columbia University, and a bachelor’s degree in Chemistry and Theology from St. Olaf College. Outside of work, he enjoys reading science fiction, playing tennis, and spending time with family and friends.
