The Biosolids Emissions Assessment Model (BEAM) – Estimating Greenhouse Gas Emissions from Biosolids Management
Municipal wastewater treatment produces biosolids that require management. Biosolids management practices can impact anthropogenic (from human activities) emissions of greenhouse gases (GHGs). An example of anthropogenic emissions are those generated through the combustion of fossil fuels. The most important GHGs that relate to biosolids management include carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Changes can be made to biosolids management practices and programs to minimize GHG emissions, thereby lessening the impacts of the wastewater treatment industry on the environment.
To facilitate assessments of the GHG emissions from biosolids management practices, the Canadian Council of Ministers of the Environment (CCME) commissioned the development of a model for estimating emissions from common practices. SYLVIS Environmental of New Westminster, BC and its project team consisting of Dr. Sally Brown (University of Washington), Ned Beecher (North East Biosolids & Residuals Association), and Andrew Carpenter (Northern Tilth) developed the Biosolids Emissions Assessment Model, or BEAM, for the CCME.
