The STEPS Summer 2023 REU Program is Accepting Applications
The Science and Technologies for Phosphorus Sustainability (STEPS) Center is a convergence research community of diverse and leading scientists that addresses the complex challenges in phosphorus sustainability by integrating disciplinary contributions across the physical, life, social, and economic sciences. The STEPS vision is to facilitate a 25% reduction in human dependence on mined phosphates and a 25% reduction in losses of point and non-point sources of phosphorus to soils and water resources within 25 years, leading to enhanced resilience of food systems and reduced environmental damage.
Lucas Crane, Masters Student - Lucas is a current M.S. student and future Ph.D. student in Environmental Engineering at Arizona State University working under Dr. Treavor H. Boyer, Professor of Environmental Engineering. His primary research interests are in physicochemical characterization and treatment of water and wastewater, including waste-to-benefit reuse of human urine, implementation of urine collection systems, and application of sensing technologies in premise plumbing systems. In his undergraduate research, he designed a novel biocementation process using human urine and calcium-rich zeolites to reduce the costs of reagents and minimize the environmental impact of enzyme-induced carbonate precipitation; this work was recently published in the Journal of Environmental Chemical Engineering. In his master's research, he is investigating the permeation of urea from human urine through reverse osmosis and nanofiltration membranes. In STEPS, he will be continuing his study of urine by investigating the recovery of phosphate from human urine via chemical precipitation and electrochemistry and modeling flows of phosphorus in wastewater distribution systems.Read More
Updates to the MANAGE Database Facilitates Regional Analyses of Nutrient Runoff
Debabrata Sahoo details efforts to update the Measured Annual Nutrient loads from Agricultural Environments (MANAGE) database. For model evaluations, scientific analyses, policy and management decisions the data repository is available in the USDA Ag Data Commons. MANAGE was developed originally in 2006 to summarize nitrogen and phosphorus runoff data from agricultural land use.
The STEPS Center and Sustainable Phosphorus Alliance Celebrated P Week 2022
The event combined a two-day Phosphorus Forum event (November 1 and 2) with a two-day Sustainable Phosphorus Summit (November 3 and 4). Attendees networked and shared knowledge with diverse organizations and people to improve phosphorus sustainability all along the phosphorus value chain. The event was held jointly at the Sheraton in downtown Raleigh and the Plant Sciences Building on North Carolina State University’s Centennial Campus.
Contributions of Healthier Diets and Agricultural Productivity Toward Sustainability and Climate Goals in the United States
Research Theme 3 Co-lead Justin Baker and Ph.D. student Chris Wade explore the indirect reduction of greenhouse gas emissions through seven scenarios of varying U.S. crop yields and healthier diets in both the United State and abroad. Results utilizing the US Fable Calculator and GLOBIOM suggest significant contributions can be achieved toward meeting U.S. long-term climate goals for land use sectors.
