The search of sustainable and environmentally friendly alternatives to obtain compounds for different industrial sectors has grown exponentially. Following the principles of biorefinery and circular bioeconomy, processes in which the use of natural resources such as macroalgae biomass is prioritized are required. This review focuses on a description of the relevance, application and engineering platforms of hydrothermal systems and the operational conditions depending on the target as an innovative technology and bio-based solution for macroalgae fractionation in order to recover profitable products for industries and investors. In this sense, hydrothermal treatments represent a promising alternative for obtaining different high value-added compounds from this biomass; since, the different variations in terms of operating conditions, gives great versatility to this technology compared to other types of processing, allowing it to be adapted depending on the objective, whether it is working under sub/super critical conditions, thus expanding its field of application.
为了在不同的工业领域获得化合物，人们一直在寻找可持续且环保的替代品，这种需求呈指数级增长。遵循生物炼制和循环生物经济的原则，需要优先使用自然资源（如大型藻类生物质）的工艺。本综述重点介绍了水热系统的相关性、应用和工程平台，以及根据目标作为一种创新技术和基于生物的大型藻类分级解决方案的操作条件，以便为工业和投资者回收有利可图的产品。从这个意义上说，水热处理是从这种生物质中获得不同高附加值化合物的有前途的替代方法；因为，操作条件的不同变化使这项技术与其他类型的加工相比具有更大的通用性，允许根据目标进行调整，无论是在亚/超临界条件下工作，从而扩大其应用领域。
