  • Enhanced Efficiency Fertilizer Challenge

    graphic identifier for the enhanced efficiency fertilizer challenge

    This Challenge aims to identify existing enhanced efficiency fertilizers (EEFs) currently on or near-market that meet or exceed certain environmental and agro-economic criteria. The EEF challenge is also a part of the larger Next Gen Fertilizer Challenge.

    No longer accepting submissions. 

    Learn more about the EEF and Next Gen Fertilizer Challenges
  • Cleaner Indoor Air During Wildfire Challenge

    graphic identifier for the Cleaner Indoor Air During Wildfires Challenge

    This challenge was the first step in EPA's effort to stimulate the development of new technologies to clean indoor air. It offered a cash prize for the best technology design for cleaning indoor air during wildfire smoke events and high pollution days.

    Currently testing phase 2 prototypes. Winners expected to be announced in spring 2023.

      Learn more about the Cleaner Indoor Air During Wildfire Challenge.
    • Make A Market Tech Challenge

    As a part of the larger Next Gen Fertilizer Challenges, this challenge aimed to identify concepts for novel fertilizer technologies and other product innovations that could reduce the environmental effects from modern agriculture while maintaining or increasing crop yields. Submissions included technologies not currently on the market. 

    • Learn more about the Next Gen Fertilizer Challenges.

    EcoTox TARGET Challenge

    EcoTox Target Challenge

    The Technology Advancing Rapid Gene Expression-based Testing (TARGET) challenge called for respondents to develop high quality, low cost, technologies/platforms for evaluating global gene expression in samples from four common aquatic toxicity test organisms. 

    • Learn more about the EcoTox TARGET Challenge.

    Campus Rainworks Annual Challenge

    This is a green infrastructure design competition for U.S. colleges and universities that seeks to engage with the next generation of environmental professionals, foster a dialogue about effective stormwater management and showcase the environmental, economic, and social benefits of green infrastructure practices. (Stage 3). 

    • Learn more about the Annual 2021 Campus Rainworks Challenge.

    Nutrient Sensor Action Challenge

    The Nutrient Sensor Action Challenge was a technology-accelerating water quality challenge launched in 2017 to demonstrate how nutrient sensors can be used by states and local communities to help manage nutrient pollution.
