Hazen Joins Industry Leaders to Host Bioenergy and Co-Digestion Webinar

(NEW YORK, NY - April 20, 2023) – Hazen and Sawyer is taking part in a Pacific Northwest Clean Water Association webinar focused on the important discussion of how changing climate change regulations aimed at reducing Greenhouse gas emissions are affecting water reclamation and recovery facilities (WRRFs) across the U.S. Taking place April 25 from 1-3 p.m. (PST), the Bioenergy and Co-Digestion webinar will provide utility managers and staff valuable guidance on how to effectively manage methane emissions from decomposing organic waste in landfills.

In the Pacific Northwest specifically, new legislation aimed at addressing global climate change is posing several challenges to WRRFs, especially as diverting organics from landfills – which includes food waste, wood and paper, organic textiles, manure, sludge, digestates, and biosolids – is becoming more frequent. During the webinar, utilities will learn how to plan for these changes without incurring negative business impacts and also gain insight on developing a cost-benefit model customized to their goals and needs.

Hazen’s Energy Management Group Leader Bryan Lisk, Residuals and Biosolids Practice Group Lead Dr. Derya Dursun, and engineer Riley Murnane will lead discussions on bioenergy and biosolids master planning, Source Separated Organics (SSO) pretreatment, and diverting organics from landfills, respectively. They will be joined by Josh Newman from the City of Portland Bureau of Environmental services and Mark Van Eeckhout from the City of Springfield Metropolitan Wastewater Management Commission.

The agenda for the webinar includes:

• Overview and trends of organic diversion regulations
• Impacts and opportunities for utilities
• Planning for accepting SSOs
• Trends and barriers to recovering energy and resources from SSOs
• Cost-Benefit model and case studies
