In the Sustainable P Initiative blog young scientists from Arizona State University (ASU) discuss current themes and issues in phosphorus research.

  1. But Trees Can Grow on Money: Blue Plains WWTP Tour

    In my interest to learn about phosphorus recovery from wastewater, I recently toured the Blue Plains Advanced Wastewater Treatment Plant located in Washington DC. Since it serves the nation’s leaders, the plant operators see themselves as being leaders in implementing the paradigm shift from wastewater treatment to resource recovery. The plant collects 370 million gallons each […]
  2. Output of P RCN Meeting in D.C., May 2015

    On May 18-21, 2015, scientists of the P Sustainability Research Coordination Network (RCN) reconvened in Washington, D.C. for the third annual P RCN meeting. In this meeting, the P RCN moves on from Phase I’s focus on the two P sustainability challenges of “improving P efficiency in food production” and “developing robust pathways of P recycling”. Phase II […]
  3. Urinals Save the Day

    My longtime friend and college roommate is one of four sons in his family.  His mother got so sick of cleaning the bathroom that served these inaccurate marksmen growing up that she installed a urinal.  It became so famous that all the boys in the neighborhood would find excuses to come use “the target that […]
  4. The Case for Source Separation

      Source separation is a major intervention currently proposed in nutrient management with major potential to improve P reuse.  Source separation refers to keeping liquid human waste separate from solid human waste at the source.  Apparatus that can achieve this are varied, and my favorite one will be the topic of my next post.  Perhaps […]
  5. Researchers have a role to play in decreasing inequality in access to phosphorus: Thoughts from the Sustainable Phosphorus Summit

    Author:  Genevieve Metson Phosphorus as a major concern From September 1st to September 3rd 2014, scientists from around the world met at the Sustainable Phosphorus Summit 2014 in Montpellier to discuss how to better manage Phosphorus, an essential element for all of us Over the three-day conference, we heard about some of the cutting edge […]
  6. Twelve Steps to P Recovery

    Tens of thousands of people worldwide have overcome addiction using the Twelve Step Program originally proposed by Alcoholics Anonymous in 1939.  They have used these guiding principles to overcome deep challenges, and may have a lesson to teach the world about breaking its dependence and misuse of finite stores of phosphate.   Here we discuss a […]
  7. SOIL in Haiti

    In Haiti, a unique enterprise was created that improves public health while contributing to P cycling. SOIL (Sustainable Organic Integrated Livelihoods)  was created in 2006 in order to both improve access to sanitation, and create a sustainable source of fertilizer for Haitian agriculture. Using principles of ecological sanitation (EcoSan), they created toilets and a collection/maintenance […]
  8. Output from the Young Scientist Workshop, Montpellier, France, August 31st, 2014.

    In August 31, 2014, there were 42 young scientists from 20 countries gathered together at Montpellier, France at the Young Scientist Workshop in the midst of the phosphorus (P) week. These young scientists are mainly PhD students and postdoctoral fellows. This workshop was particularly focusing on developing their research network, reflecting on much broader questions […]
  9. Anaerobic digesters and P recovery

    This past summer I visited India to explore organic waste management operations that contributed to nutrient cycling. In today’s post I will discuss Jain Irrigation Systems Ltd (JISL). Founded on a philosophy that we should leave the world better than we found it, JISL pays close attention to environmental issues, farmer livelihoods, and the well being […]
  10. EPA Defines Waters of the United States

    The US Environmental Protection Agency has released a draft definition of the term “waters of the United States” as covered by the Clean Water Act (CWA). The CWA regulates entities that discharge any pollutants, including phosphorus (P), into said waters.  However, which waters are or are not covered has been very vague since its passage […]
