Greenhouse Gas Emissions & Biosolids Management
This page provides resources on greenhouse gas emissions from biosolids management and related activities. NEBRA is working with stakeholders across the continent on advancing understanding of how biooslids management contributes to climate change and how biosolids managers can optimize operations to reduce their "carbon footprint." Ultimately, biosolids can be a resource for reducing greenhouse gas emissions by providing renewable energy, reducing use of fossil fuels, and capturing carbon for sequestration in soils.

NEBRA's involvement in this topic has included:
- presenting the first stand-alone workshops on greenhouse gas emissions accounting for wastewater and biosolids management (see details and presentations, below);
- helping create the Biosolids Emissions Assessment Model (BEAM) for the Canadian Council of Ministers of the Environment, in cooperation with Sylvis Environmental (BC), Northern Tilth (ME), and Univ. of Washington (WA); the spreadsheet calculator, literature review, and full report are available for free download here;
- serving as a reviewer on the Water Environment Federation Technical Practice Update "Protocols for Estimating Greenhouse Gas Emissions from Municipal Wastewater Sources" (October 2009; available here);
- assisting with estimation of greenhouse gas emissions from the biosolids management programs at DC-WASA (Washington, DC) and Lewiston-Auburn, ME; and
- A Greenhouse Gas Emissions Analysis of Biosolids Management Options for Merrimack, NH (2008), which compares composting and landfill disposal using local data, resulting in estimates of energy use and greenhouse gas emissions for each option;

Greenhouse Gas Emissions Accounting
for
Wastewater Treatment & Biosolids Management
A NEBRA Workshop
originally presented Thursday, October 1, 2009, Lawrence, MA
Co-sponsored by U. S. EPA Region 1
This workshop provided wastewater treatment facilities, biosolids management programs, engineers, and regulatory agency staff the background and basics of GHG emissions accounting, using both standard protocols and more detailed, site-specific analysis. Topics included a brief history of GHG accounting, current leading protocols and registries (e.g. The Climate Registry and its Local Government Operations Protocol), and key accounting concepts such as scopes, tiers, and verification. Presentations will be followed by analyses of typical northeast wastewater treatment and biosolids management programs.

Workshop Instructors:
Ned Beecher, NEBRA, Tamworth, NH
Ned Beecher is the Executive Director of NEBRA. In 2008, he completed a bottom-up GHG emissions analysis for the town of Merrimack, NH biosolids management program (leading to Spring, 2009 articles in Water Environment & Technology and BioCycle). In 2008-2009, he worked with Sylvis Environmental of BC, Dr. Sally Brown of the Univ. of WA, and Andrew Carpenter (below) developing a model and spreadsheet calculator for estimating GHG emissions from a variety of biosolids management options employed in Canada. This project was by contract with the Canadian Council of Ministers of the Environment (CCME). He
was part of The Climate Registry’s wastewater treatment technical expert group for the Local Government Operations Protocol wastewater section and has presented at several regional and national conferences on GHG emissions from biosolids management.
Andrew Carpenter, Northern Tilth, Belfast, ME
Andrew Carpenter is a soil scientist and owner of the consulting firm Northern Tilth. He was a lead developer of the GHG accounting model and spreadsheet calculator for the CCME project described above. He has nearly 20 years of experience in the field of biosolids management and is a certified crop advisor and nutrient management planner. He currently serves on NEBRA’s Board of Directors and Research
Committee.
Jason Turgeon, USEPA Region 1, Boston, MA
Jason Turgeon is an Environmental Protection Specialist in the Energy and Climate Unit at EPA Region 1 in Boston, MA. He specializes in the intersection of water and energy and works mostly with municipal drinking water and wastewater systems to help them be more energy efficient and produce their own renewable energy on-site. His interests focus on applying modern technology to develop a 21st century sustainable water infrastructure that integrates the management and reuse of the water, nutrient, and energy resources found in what we now consider “wastewater.” Jason has a B.S. in Environmental Geology from Northeastern University. He is also a US Coast Guard licensed boat captain.
John Willis, Brown & Caldwell, Atlanta, GA
John Willis is a Vice President and Southeastern Wastewater Practice Leader with Brown and Caldwell and a self-admitted “sludge head”. He proudly counts himself among the lumpiest of the “lumpy water guys”. He has almost 20 years’ of experience in innovative and sustainable biosolids-producing project experience including:
1. Designing the country’s first Class-A thermophilic anaerobic digestion process in Chapel Hill, NC;
2. Involvement in DCWASA’s egg-shaped digestion design and current Cambi Biosolids Program; and
3. Principal investigator for development of Columbus Georgia’s CBFT3 Class-A digestion and CHP facilities.
He has conducted greenhouse gas emissions analyses for several treatment facilities, including Orange Water & Sewer Authority in Chapel Hill, NC and the DC Washington and Sewer Authority. He is a part of WEF's Carbon Task Force.
