Abstract

The present work conducts a detailed technoeconomic analysis of an environmentally friendly zero-waste biorefinery process to valorize marine Ulva fasciata 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 Ulva fasciata 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.

从大藻中环保提取可持续增值产品：整体技术经济分析。

本研究对一种环境友好的零废物生物炼制工艺进行了详细的技术经济分析，以将海洋大藻转化为不同的可持续增值产品。所提出的顺序完全集成工艺产生了34.89%富含矿物质的水提取物（MRWE）， 2.61±0.5%叶绿素，0.41±0.05%类胡萝卜素，12.55±1.6%淀粉，3.27±0.7%脂质，22.24±1.8% ulvan, 13.37±1.5%蛋白质和10.66±0.9%纤维素。利用非随机双液（NRTL）模型的Aspen Plus软件用于工艺设计、仿真和技术经济分析。主要发现包括净现值（NPV）为49,755,544.90美元，投资回报率（ROI）高达485%，内部收益率（IRR）为17%。预计投资回收期为7年，前期投资可迅速收回。这些研究结果证实，在生物炼制行业中，海藻是一种很有前途的资源，为生物基产品的生产提供了一种可行的、环保的替代品，也为海藻基产品开辟了一个新的市场。
