Tidal Vision: Extracts chitosan from discarded crab shells to produce inputs with better performance, economics, and sustainability

Founded in 2015, Tidal Vision is a biomolecular technology company that extracts chitosan from discarded crab shells to produce biodegradable solutions for agriculture, water treatment, and materials applications. The company has developed a proprietary, cost-effective and environmentally friendly extraction process that enables chitosan to replace legacy inputs at industrial scale. With rapidly growing commercial traction across its Tidal Grow, Tidal Clear and Tidal Tec divisions, Tidal Vision is emerging as a leading player in sustainable chemistry and circular-economy innovation.

Beating legacy inputs on performance, economics, and ease of use, while meeting growing sustainability demands

Tidal Vision is transforming water treatment and agriculture with their versatile low-cost chitosan platform. In agriculture, Tidal Grow develops products that use chitosan to enhance the delivery and uptake of fertilizer and pesticides, while also benefiting from chitosan’s plant defense elicitor and antimicrobial properties. These precisely engineered chitosan technologies help growers get more value for each nutrient and pesticide input applied, enabling higher yields with less inputs. In water treatment, Tidal Clear’s chitosan-based formulations can replace 90% of commodity water treatment chemicals, while also requiring less inputs and producing less sludge. Tidal Clear’s integrated dosing systems and chitosan-based formulations lower water treatment costs for customers. Tidal Vision’s ability to extract chitosan and modify it for varied applications is a disrupting innovation that offers better performance per dollar compared to legacy products. Through superior efficacy, Tidal Vision’s products enable customers to do more with less and reduce the use of harmful inputs.

Ocean Impact: Cutting Nitrogen Runoff

Tidal Vision tackles a major threat to ocean biodiversity: nitrogen runoff. Excess nitrogen from synthetic fertilizers drives coastal eutrophication, oxygen depletion, and biodiversity loss, with up to 75% of applied nitrogen lost through runoff or leaching—potentially exceeding 10 million tons per year globally. Tidal Grow formulations enable farmers to reduce nitrogen fertilizer use by more than 10% and pesticide use by over 50%, significantly lowering nutrient runoff, greenhouse gas emissions, and chemical pollution.
