Session G: Technological Considerations for Processing Organics

Friday, May 19, 10:30 a.m. - noon -- Venice Room

SJAlberta Organics Diversion and Implications for Leachate Quality -- Steve Johnson, AECOM
Steve has an undergraduate degree in Civil Engineering and a Masters in Environmental Engineering from the University of Alberta. He has worked for Hydrogeological Consultants, Alberta Environment, Waste Management of Canada, and AECOM throughout his career specializing in waste management over the past 15 years. At Hydrogeological Consultants he conducted landfill groundwater monitoring programs and surface water availability evaluations. While at Alberta Environment he was an approval writer for landfills, water, and waste water treatment facilities and then the Province's Landfill Specialist instrumental in the development of the Standards for Landfills in Alberta, the Guidelines for Landfills in Alberta, and initiating the Standards for Composting in Alberta. While at Waste Management, Steve was the Site Engineer responsible for landfill capping, developing and operating a leachate treatment plant, waste acceptance approvals, regulatory reporting, gull control, and the upgrade to a landfill gas collection and flaring system. At AECOM, he has conducted projects in airspace assessments, transfer station design, and landfill design. He has presented frequently at SWANA conferences and is a SWANA instructor for the landfill basics course.

DMApproaches to Selecting Food Waste Processing Technologies -- Darryl McCartney, University of Alberta
Daryl is a Professor of Environmental Engineering at the University of Alberta and the Executive Director & Director of Research at the Edmonton Waste Management Centre of Excellence, a not-for-profit agency supporting research and development waste management. His current research program is focused on organic waste utilization, e.g. source separation of ICI organics; integrating anaerobic digestion processes into existing composting facilities; and optimization of full-scale composting facilities. During his career, he has authored or co-authored over 170 journal manuscripts, conference papers, and technical report publications. Daryl currently sits on the editorial board of the Journal of Compost Science & Utilization; and the University of Alberta’s Waste Diversion Working Group.

 AHEconomics of Dry Batch Digestion for Small Municipalities – An Alberta Case Study -- Alex Hayes, Alberta Innovates
Alex is a research engineer with InnoTech Alberta, an applied research organization, where he works in a group focused on value-added processes for organic residuals and wastewater. Through a combination of strategic applied research and client-focused projects, Alex helps facilitate the growth of the biogas industry in Alberta. Alex has worked on the implementation of biogas solutions in several sectors, including municipal, agriculture and agri-food, forestry and oil and gas where he has performed technical and economic assessments surrounding the integration of anaerobic digestion processes into industrial operations. Prior to joining InnoTech Alberta, he worked at the National Research Council after completing his PhD at the University of Toronto.
