Assessment of Sargassum spp. Management Strategies in Southeast Florida

This study evaluated the economic viability of Sargassum management strategies in southeast Florida. Semi-structured interviews were conducted with key informants, beach managers and potential users. To compare the strategies, a cost and market analysis was conducted to assess the value of Sargassum compost relative to other compost products available in the market. The findings indicate that composting Sargassum is an economically viable option and suggests the potential for recouping some of the costs associated with beach cleaning through the sale of compost. Furthermore, the utilization of Sargassum compost could offer a cost-effective alternative as a soil amendment, especially in the face of rising fertilizer costs. However, it is crucial to address concerns regarding compost quality due to contaminants such as plastics and arsenic before implementing a composting operation. This aspect necessitates thorough investigation and remediation to ensure that the resulting compost meets quality standards and is free from potentially harmful contaminants.
