Join us for an extra special Australian & New Zealand Biosolids Partnership Lunch and Learn Webinar with our guest speakers from Canada and the USA!
Professor Grant Clark (Canada) will outline how he leads the Ecological Engineering Research Group, investigating nature-based technologies for responsible civilisations on small planets. More than 750,000 dry metric tons of sewage sludge are produced annually in Canada. Instead of landfilling or incinerating the sludge, it is increasingly processed into biosolids and applied to agricultural fields as organic fertiliser. We often assume that the greenhouse gas emissions (GHGs) resulting from this practice are net-negative, but this has not been well studied. To help address this research gap, Grant conducted field experiments at sites in Truro (Nova Scotia), Montreal (Quebec), and Edmonton (Alberta). Sewage sludge was either anaerobically digested, composted, or alkaline stabilized.
Janine Burke-Wells and Ned Beecher (USA) from North East Biosolids & Residuals Association (NEBRA) will discuss how water resource recovery facilities (WRRFs) manage their “waste” solids can have a major impact on their total net greenhouse gas (GHG) emissions. This presentation will introduce the Biosolids Emissions Assessment Model (BEAM), a calculator tool for getting a handle on your WRRF’s biosolids management GHG emissions. BEAM*2022 can be used to estimate and compare carbon emissions from up to 10 biosolids management options. Several examples will be cited, showing how using the BEAM can help WRRFs better understand the factors that have the greatest impacts on GHG emissions. Links to key resources and the BEAM*2022 will be provided.
These presentations will followed by Q&A sessions afterwards. We look forward to seeing you in the webinar.
