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 create video abstracts of phosphorus sustainability research that has been published recently in respected, peer-reviewed journals through our series Phosphorus Science Now! The video abstracts are 5- to 10-minutes long and the researchers present their own findings.

Phosphorus Turns 350
While phosphorus is billions of years old, it has only been known to us as an element for 350 years. We’re celebrating this anniversary with a webinar that surveys its history, applications, and enabling role in humanity’s dysfunctional relationship with Mother Nature. Coverage will include a summary from Lancaster University’s event “Phosphorus350 – A Turning Point in Phosphorus Stewardship” by Dr. Rachel Marshall of Lancaster University, a history of phosphorus presented by Dr. Helen Jarvie of the UK’s NERC Centre for Ecology and Hydrology, and a review of a coming book about phosphorus by Alliance Director, Dr. Jim Elser, and Lancaster University professor, Dr. Phil Haygarth. Please join us for this 90-minute webinar with ample time for questions.

Webinar – Upcycling Phosphorus for Agricultural Use
The term “upcycling” describes transforming wastes or otherwise low-value products into more valuable products, particularly those of higher environmental value. The upcycling of phosphorus from effluent, biosolids, and manures can yield various types of fertilizers for crops, thereby closing the loop on the nutrient cycle. These products may offer substantial advantages–agronomic, environmental, regulatory–over simply applying the wastes from which they were derived to plants.
In this webinar, we will discuss three such products with their purveyors and ask about the challenges to producing the products, their appropriate uses, their agronomic and environmental benefits, their comparability to more traditional products, and the regulatory complexity surrounding their use.
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.
