Nitrogen and Co-Pollutants Research Roadmap

U.S. EPA’s Office of Research and Development released “Nitrogen and Co-Pollutants Research Roadmap” in which biosolids was noted as part of  “Science Challenge 4 – What are some new, innovative approaches we haven’t tried before?  Traditional regulatory and non-regulatory measures may not be sufficient to achieve the goals established for a priority area. Innovative approaches that go beyond individual sources may be necessary to be more effective, efficient, socially acceptable and sustainable. [. . . . ]  Sub-output: Provide technical support to design sustainable approaches, beyond current regulatory approaches, to manage nitrogen and co-pollutants that consider multimedia pathways of nitrogen and co-pollutants. Issues may involve: whole farm analysis of Nr and co-pollutant pathways; modeling of nitrogen and co-pollutant emissions generation from alternative energy systems; co-management of animal manure and municipal biosolids in anaerobic digesters; WWTP nutrient recovery from wastewater streams; and calibration of fertilizer application rates for site-specific conditions.
