Macroalgae are promising substitutions for land-based crops. Their biomass can be processed into various products, and their cultivation sequester carbon bioextract nutrients from coastal waters. This study investigated the economic cost environmental impacts of multiple seaweed platforms, strategies, processing / end-use strategies through techno-economic analysis (TEA) life cycle assessment (LCA), with focus on Saccharina latissima ( S. ) Gracilaria tikvahiae G. ). Cultivation platforms included single layer longline, dual strip, strip systems. Processing products to biofuel, dried sea vegetables, marketable commercial fertilizer, animal feed. Compared alone (singular grow-out), addition rotation reduced both costs regardless platform product. Economic were decreased highest using common longline system ($4.44 kg -1 dry weight (dw) $6.73 dw when cultivated rotation). The use $2.19 $3.43 . Seaweed drying was major contributor macroalgae processing. Yet, vegetables offset vegetable production had best performance human non-carcinogenic toxicity, marine eutrophication, freshwater ecotoxicity, terrestrial ecotoxicity. Use as biofeedstock anaerobic digestion combined heat power resulted in fossil resource scarcity, global warming potential, carcinogenic toxicity. It also performing product
