Coastal Biotech is a marine biotechnology company based in Zanzibar, Tanzania, that develops sustainable, seaweed-derived biostimulants and bio-materials to decarbonize agriculture and replace synthetic chemical inputs.
Coastal Biotech is a marine biotechnology company headquartered in Zanzibar, Tanzania, that specializes in developing sustainable products derived from macroalgae (seaweed). The company utilizes advanced plant molecular biology, biochemistry, and green chemistry to produce high-performance organic biostimulants and bio-based materials. Their core technology focuses on extracting bioactive compounds—such as polysaccharides, amino acids, and phytohormones—to create agricultural inputs that enhance nutrient use efficiency, stress tolerance, and crop yields. By integrating international biotech standards with local agronomic knowledge, they provide scalable, regulatory-compliant manufacturing solutions designed to replace traditional synthetic fertilizers and pesticides.
The company's solutions are vital for farmers and agrochemical formulators seeking to transition to sustainable, net-zero production models without significant capital expenditure. Coastal Biotech partners with agricultural organizations, such as the Tanganyika Farmers Association (TFA), to implement large-scale organic fertilizer projects aimed at reducing input costs and improving food security. By operating at the intersection of nature and technology, they provide businesses with a reliable supply of processed seaweed and high-value marine ingredients, helping manufacturers accelerate their green transitions while streamlining R&D and production cycles. Their work supports climate change adaptation and promotes environmentally friendly cultivation methods across emerging markets.
