Sea4Earth farms macroalgae in European coastal waters and processes it into protein‑rich, food‑grade ingredients using seawater and renewable energy. Their offshore cultivation and full‑chain processing deliver low‑water, low‑carbon protein flours, powders, and extracts that food manufacturers and plant‑based product developers can use as sustainable alternatives to traditional crops and livestock.

Problem
Current food production relies heavily on land-based agriculture, which faces constraints such as limited fertile soil, freshwater scarcity, and high greenhouse‑gas emissions. These pressures make it difficult to meet the projected 56% increase in global food demand by 2050 while maintaining environmental sustainability.
Solution
Sea4Earth cultivates macroalgae at industrial scale in European coastal waters and processes the biomass into food‑grade ingredients rich in protein and nutrients. By using seawater and renewable energy, the company produces a land‑independent protein source that reduces reliance on crops and livestock, thereby lowering carbon emissions and water use. The cultivated seaweed is harvested, cleaned, and transformed into ready‑to‑use food products that can be incorporated into a variety of consumer and industrial food applications. Sea4Earth’s approach also creates skilled maritime jobs and revitalizes coastal economies, supporting regional food sovereignty and climate goals.
Target Audience
Primary customers are food manufacturers, plant‑based product developers, and retailers seeking sustainable protein ingredients, as well as environmentally conscious consumers looking for alternative food sources.
