Marine macroalgal resources are gaining importance as one of the promising feedstocks for the production of food, feed, chemicals and energy which are upwardly growing worldwide. Recent studies have convincingly demonstrated the scope and potentials of seaweeds for the production of diverse bioproducts of commercial importance. The present study demonstrates an integrated strategy for sustainable utilisation of wet brown algal biomass (Sargassum) in laboratory-scale at 1 kg batch processing yielding 541.33 ± 5.50 mL sap, 32 ± 1.5 g alginic acid, 3.8 ± 0.2 g protein concentrate and 10 ± 0.5 g cellulose. Furthermore, the effluent obtained from the process was used to produce as much as 115 ± 5 g salt. The present integrated process has several advantages over contemporary ones in terms of reduction in input chemicals, and total utilisation of feedstock with effluent management. The green matrix analysis and economic assessment suggested that the commercial-scale implementation of the process could help to reduce the energy and chemical inputs for components extraction which are the major challenges with seaweed bioprocessing.

海洋大型藻类资源作为生产食品，饲料，化学药品和能源的有前途的原料之一，正变得越来越重要，该原料在世界范围内正在不断增长。最近的研究令人信服地证明了海藻在生产具有商业重要性的多种生物产品方面的范围和潜力。本研究证明了湿褐藻生物质（Sargassum）可持续利用的综合策略）以1 kg批量处理的实验室规模生产541.33±5.50 mL汁液，32±1.5 g海藻酸，3.8±0.2 g浓缩蛋白和10±0.5 g纤维素。此外，从该过程中获得的流出物可用于生产多达115±5 g的盐。在减少输入化学品以及在废水管理中全面利用原料方面，本综合工艺与现代工艺相比具有许多优势。绿色矩阵分析和经济评估表明，该工艺的商业规模实施可以帮助减少用于成分提取的能源和化学投入，这是海藻生物加工的主要挑战。
