对具有生物功能特性的天然产品的新来源存在广泛的需求，其中大型藻类可以是满足这种需求的相关组分。如今，在一些国家，没有商业规模的农作物供应生物质市场供开发。具有潜在应用价值的海滩海藻生物质的高可用性使其成为满足这一需求的有吸引力和可持续的替代品。目前，海滩上过多的海藻造成了环境问题，因为海藻的分解影响了海滩的使用，使游客和游泳者望而却步，影响了该地区的财政收入。考虑到这种对环境的负面影响和使用这种生物原料的可能性，一些国家规定了配额，以便能够减少数量并保持环境中的库存。本综述旨在收集有关世界和巴西海滩投掷海藻的研究信息，解决生态，经济和潜在的应用。开发海滩藻类可以是一个社会经济和环境可持续的解决方案，因为它降低了财务成本，为当地居民创造了替代收入，并限制了开采对受到过度开发威胁的天然大型藻类床的影响。鉴于藻类基质技术的发展，这一材料的相关性通过收集关于生物质勘探的信息来显示，重点是功能产品的开发和被视为废物的未开发生物质的可持续利用。利用海滩上的海藻作为资源是一种生态高效的替代方案，有利于社会和环境，产生以前被视为有限和垃圾的可用资源。除了鼓励沿海地区减轻污染和可持续的社会经济发展之外。在这次审查中提出的数据将显着贡献，增加世界各地的海滩铸造海藻及其潜在用途的知识。
There is an extensive demand for new sources of natural products with biofunctional properties, in which macroalgae can be relevant components to encounter this need. Nowadays, there are no commercial-scale alga crops to supply the biomass market for exploitation in some countries. The high availability of beach-cast seaweed biomass with potential application makes them an attractive and sustainable alternative to satisfy this demand. Currently, the excess of beach-cast seaweeds on the beaches causes an environmental problem, as its decomposition affects the use of the beach and keeps tourists and bathers away, affecting financial income in the region. Considering this negative impact on the environment and the possibility of using this biological feedstock, some countries establish quotas that make it possible to reduce the volume and maintain the stock in the environment. This review aims to gather information on studies related to beach-cast marine algae in the world and Brazil, addressing ecological, economic, and potential applications. The exploitation of beach-cast algae can be a socio-economic and environmentally sustainable solution, since it reduces financial costs, generates an alternative income for the local population, and limits the impact of extraction on natural beds of macroalgae, threatened by over-exploitation. The relevance of this material is shown by gathering information on the prospecting of the biomass given the development of technology for algae matrices with a focus on the development of functional products and sustainable use of unexplored biomass considered as waste. The use of beach-cast seaweeds as a resource is an eco-efficient alternative that favors society and the environment, generating usable resources that were previously seen as limited and trash. In addition to encouraging pollution mitigation in coastal regions and socioeconomic development sustainably. The data presented in this review will significantly contribute, increasing the knowledge of beach-cast seaweeds worldwide and their potential uses.
