Summary:
A collaboration between Tulane University, the University of Maryland, and Mote Marine Laboratory has invented HAB-Away, a foaming solution to harmful algal blooms (HABs) in large bodies of water. The foaming action of this solution keeps algicide at the surface of the water where it kills harmful algae without harming aquatic life deeper in the water. Over time, the foam dissipates without a trace, and the dead algae sink to the water floor. Treating harmful algae blooms in large bodies of water is difficult, as traditional algicides would be rapidly diluted by the water, mostly killing fish below the surface rather than the algae at the surface. HAB-Away integrates algicides into eco-friendly foams, providing a novel method for controlling algal blooms. Unlike traditional treatments, these foams are biocompatible and can be easily transported and applied over large water surfaces. By restricting algicide to the water’s surface, organisms that live deeper in water are totally unaffected, and lower quantities of potentially harmful chemicals are used overall. Benefits include improved water quality, enhanced public health, and reduced environmental impact. Beyond public and environmental advantages, HAB-Away is useful in industries reliant on clean water, such as municipal water treatment, fisheries, and tourism. There is no existing gold standard for mitigating harmful algae in large bodies of water, making this a potential best-in-class product. Moreover, prospective investors and funders should be interested in this technology due to its efficiency, sustainability, and cost-effectiveness. The foam is flexible, being adaptable for different environments (e.g., fresh water vs marine) and/or different delivery mechanisms (spraying from shore, spreading via aircraft, etc.). These make it a practical solution for widespread application. Additionally, its eco-friendly composition aligns with the growing demand for green technologies, offering a competitive edge in the market. The technology's potential to reduce environmental damage and improve water quality can lead to significant cost savings in water treatment and management, making it an attractive investment for those looking to support innovative and impactful solutions. Field demonstrations in water of increasing size are planned later in 2025 through a contract with the US Army Corps of Engineers. Tulane seeks a partner for direct licensing or an entrepreneur to build a business around this technology. Patent applications are pending.
