Article Abstract
The present work conducts a detailed technoeconomic analysis of an environmentally friendly zero-waste biorefinery process to valorize marine macroalgae into different sustainable value-added products. The proposed sequential fully integrated process yielded 34.89% mineral-rich water extract (MRWE), 2.61 ± 0.5% chlorophyll, 0.41 ± 0.05% carotenoids, 12.55 ± 1.6% starch, 3.27 ± 0.7% lipids, 22.24 ± 1.8% ulvan, 13.37 ± 1.5% proteins, and 10.66 ± 0.9% cellulose. The Aspen Plus software, utilizing the nonrandom two-liquid (NRTL) model, was applied for process design, simulation, and technoeconomic analysis. Key findings include a positive net present value (NPV) of $49,755,544.90, a high return on investment (ROI) of 485%, and an internal rate of return (IRR) of 17%. The anticipated payback period is 7 years, indicating a quick recovery of the initial investment. These findings confirm that is a promising resource in the biorefinery industry, providing a viable and eco-friendly alternative for the production of bio-based products and a new market for seaweed-based products.

Alkaline pretreatment is the most widely employed chemical process for lignocellulosic biomass, particularly at an industrial scale. However, this method generates a significant volume of complex wastewater, which contains recalcitrant organic molecules, high concentrations of biopolymers, and hazardous chemicals. These waste streams have been largely overlooked, with conventional disposal methods, such as incineration in recovery boilers, posing serious environmental and resource inefficiency concerns.

Pervaporation, combined with other separation processes, can effectively remove water from fermentation product streams, making it highly suitable for purifying alcohols like 2,3-butanediol (BDO). In this study, a dense poly-(vinylidene fluoride) (PVDF) hollow fiber membrane module prototype was fabricated for BDO dehydration, achieving >0.2 LMH total flux and >95% BDO rejection.
