“Our goal is to bring materials that replenish the planet into the mainstream,” says Julia Marsh, CEO and co-founder at Sway. “With backing from one of the most prestigious science organizations in the world, Sway is poised to evolve our home-compostable seaweed resins at a scale that will meaningfully support ocean farmers and transform the packaging materials we interact with daily.”

Sway will seek to expand the diversity of its feedstock portfolio, including unrefined seaweed, processing byproducts and invasive macroalgae.

“NSF accelerates the translation of emerging technologies into transformative new products and services,” says Erwin Gianchandani, assistant director for technology, innovation and partnerships at the NSF. “We take great pride in funding deep-technology startups and small 911±¬ÁÏÍøes that will shape science and engineering results into meaningful solutions for today and tomorrow.”

Companies awarded a Phase I SBIR grant are eligible to apply for Phase II funding and additional supplements totaling up to $2 million.
