Upcycling agro wastes as additives for sustainable roadway anti-icing operations

Building on the success of a Washington State University (WSU) patent technology, this project will further upcycle agro wastes from the State of Washington and turn them into novel anti-icing liquids for the market, tailored to meet the varying requirements in anti-icing performance, cost-effectiveness, and minimized footprint. The products will reduce the amount of chloride salt by at least 20% while achieving better overall performance than beet juice/salt brine blends (and salt brine). Second, they will feature greatly reduced oxygen demand and aquatic toxicity (key differentiator). Project tasks include: further development in the lab; WSU parking lot tests; and city street testing of the developed anti-icing liquids.
