Description
The Nutrient Recycling Challenge was a prize competition that EPA launched in 2015 in collaboration with 20 organizations to spur development of affordable technologies that recover nitrogen and phosphorus from dairy and/or swine manure and create value-added products that producers can use or sell. To build on the successes of the Nutrient Recycling Challenge, in 2019, the EPA signed a Memorandum of Understanding (MOU) with The Water Research Foundation (WRF) to accelerate progress on reducing excess nutrients in the nation’s waterways.

Overview
Every year, livestock producers manage over a billion tons of animal manure containing valuable nutrients—nitrogen and phosphorus—that plants need to grow. A major use of manure is as a renewable fertilizer, but it should be used properly to minimize water pollution and build healthy soils. In addition, there is a tremendous opportunity to generate environmental and economic benefits from manure by-products, but further innovation is needed to develop more effective and affordable technologies that can extract nutrients and create products that farmers can use, transport, or sell more easily to where nutrients are in demand. The mission of the Nutrient Recycling Challenge was to help find technologies that are a win-win for the environment, farmers, and the economy.
Phase II Program
Phase II (2016-2017) of the Nutrient Recycling Challenge was a non-competitive incubation program to support innovators as they developed Technology Designs based on the Concept Papers submitted in Phase I. EPA and its Partners supported the innovators with informational webinars and workshops, individualized feedback, and other resources to maximize their ability to develop designs for effective and affordable technologies.- Nutrient Recycling Challenge Phase II Announcement Factsheet (Nov. 2016)
- Nutrient Recycling Challenge Phase II FAQs (Oct 2016)
Background: Phase I
EPA received 75 concept papers from around the world in Phase I (2015), and selected 34 submissions to continue on to Phase II of the challenge. On March 30, 2016, EPA announced the winners and awarded a total of $30,000 in cash prizes to the top 10 submissions (four “Winners” and six “Honorable Mentions”). The 34 selected submissions were also invited to the Nutrient Recycling Challenge DC Summit in Washington, DC on March 30-31, 2016, during which the winners received their awards at a ceremony at the White House Eisenhower Executive Office Building. The summit provided a forum for innovators to meet Partners, experts, and other innovators, as well as learn about resources to develop their ideas into real-life technologies. EPA sought to create a “brain trust” to design nutrient recovery technologies to achieve what both farmers and the environment need.
