Anaerobic Digestion Biorefinery: Potential for Biochar Production and Utilization


February 24, 2016 10am PST. Webinar Recording below.

Speaker: Dr. Manuel Garcia-Perez, Associate Professor at the Department of Biological Systems Engineering, Washington State University.

Webinar description: Dr. Garcia-Perez will discuss the challenges and opportunities for integrating emerging technologies with existing anaerobic digestion (AD) systems as a way to gradually convert AD units into biorefineries. The focus of this webinar is on pyrolysis and gasification, two technologies that are capable of converting the digested fibers into a bio-char, and that can be integrated with AD. During the presentation Dr. Garcia-Perez will also discuss some of the potential uses of these chars in anaerobic digestion systems.

Webinar learning objectives:

1) The technical and environmental performance of anaerobic digestion systems can be improved if new emerging technologies are introduced. At the end of the webinar the participants should know some of the technologies that are currently being studied to convert anaerobic digesters into biorefineries.

2) The participants will learn how biochar is produced, the effect of production conditions on the physico-chemical properties of these materials, and how these properties could influence the use of bio-char in nutrient recovery systems.

Garcia-PerezDr. Manuel Garcia-Perez is an Associate Professor in Biological Systems Engineering at Washington State University. He works—and has worked for the last 15 years—on projects related to the conversion of forest and agricultural biomass into bio-fuels and chemicals, mostly via thermochemical conversion. Thermochemical conversion is the process of using heat to break natural polymers into usable molecules and char. Dr. Garcia-Perez has made contributions to the understanding of thermochemical reactions of cellulose, hemicelluloses, and lignin, as well as to the characterization and uses for crude bio-oils. Currently, he is working on the development of more selective pyrolysis reactors and new concepts to refine production of pyrolysis oils and engineered carbonaceous materials. Dr. Garcia-Perez is also very active in the study of ways to integrate biomass conversion technologies into existing infrastructure—for example pulp and paper mills, petroleum refineries, corn ethanol mills, sugar cane mills—to build bio-refineries that produce fuels, particularly alternative jet fuels, and chemicals.
