The broader/commercial impact of this Small Business Innovation Research (SBIR) Phase I project is in the development of local manufacturing methods for synthesizing low-cost soil amendment and shoreline restoration products using local food waste inputs. Coastal erosion, declining soil health, and soil acidification threaten both ecosystems and human infrastructure across the United States. Traditional fertilizer products often rely on mined inputs, which are expensive, contribute to carbon emissions, and degrade land/marine environments during extraction. This project proposes transforming farmer’s food waste and seafood restaurant seashell waste into regenerative soil fertilizers and sea brick products, aimed at enhancing plant growth, improving soil health, and bolstering coastlines erosion resiliency. This effort aligns with national sustainability goals by reducing methane emissions from food waste, revitalizing degraded coastal and agricultural areas, and offering affordable alternatives to synthetic fertilizers. The proposed technology may lead to environmental solutions that transform America’s food waste (FW) liabilities into valuable soil amendments products. It could also create jobs in manufacturing such sustainable products, provide communities with access to local, renewable inputs, and position the United States as a leader in climate-adaptive infrastructure. By leveraging circular economy principles, this project may have a lasting impact on both environmenta
