The Sustainable Phosphorus Alliance hosts technical webinars on important phosphorus management issues. Our members participate in the webinars and the phosphorus sustainability community is invited to attend.
In addition, we post video abstracts of phosphorus sustainability research that has been published recently in respected, peer-reviewed journals. The video abstracts are 5- to 10-minutes long and the researchers present their own findings.
Previous webinars and the video abstracts are posted on our YouTube channel.
Webinar – Regulation of Biosolids and Manure Land Application
In the US, there is substantial state-by-state diversity in the rules for when, where, and how nutrients can be recycled through land application of biosolids and manure. This regulation impacts the recycling of nutrients in the food system, including phosphorus.
The Sustainable Phosphorus Alliance is reaching the culmination of a comparative analysis on state regulations of land application of biosolids and manure. The information is being rendered as text reports and as an online, ArcGIS Story Map.
On September 25, the Sustainable Phosphorus Alliance held a 90-minute webinar with an introduction to the reports and a demonstration some features of the ArcGIS tool.
Webinar – Phosphorus Recovery from Water Resource Recovery Facilities
Materials that were traditionally characterized as waste are often replete with commodities ready to be extracted and valorized. A number of companies have seized upon this opportunity and developed technologies that advance this beneficial reuse of phosphorus.
On May 24, the Sustainable Phosphorus Alliance held a 90-minute webinar with a discussion of the challenges and opportunities in harvesting phosphorus resources from wastewater streams.
Webinar – Extreme Climate, Extreme Phosphorus
Recent weather events around the globe–from intense hurricanes in the US to massive flooding in Asia–conform to the predictions of climate change models. If extreme weather continues to be the new normal, how will an intensification of storms affect phosphorus flows through the environment and how can we prepare for the increased phosphorus loads? In this webinar, our panelists discussed how climate change is impacting and will continue to change phosphorus flows, and what cities and farms will need to do to protect against increased phosphorus pollution of our waterways.
