International Biochar Initiative Educational Webinar Series Recording
Synergies Between Anaerobic Digestion & Biochar
October 30, 2017 | 3:30 PM - 5:00 PM ET (United States)
Research has shown that there are many synergies to be found integrating pyrolysis and gasification with anaerobic digestion (AD) systems. Carbonizing the anaerobic digested fibers could be a viable way to create adsorbent for the removal of soluble phosphorous from Anaerobic digesters effluents. Using biochar in the AD substrate can boost not only the quantity but the quality of the methane (CH4) produced. It can also reduce the H2S generated during the AD process thereby reducing wear and tear on equipment. In the webinar we will discuss the possibilities to integrate acidic biochars with dissolved air flotation systems for ammonia removal. 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.

Dr. Manuel Garcia-Perez is an Adjunct Professor at Washington State University’ Chemical Engineering and BioEngineering Department. His focus is on biomass thermochemical conversion (torrefaction, pyrolysis, gasification and combustion); development and testing of new bio-oil refineries to produce advanced bio-fuels and bio-chemicals; environmental impact of thermochemical processes research addresses the environmental burden associated with the world’s declining petroleum resources.
