The utilization of sargassum in civil construction, particularly in the production of adobe bricks and particle boards, aims to reduce the accumulation of this biomass on beaches before its decomposition, promoting a sustainable disposal method. To achieve this, chemical and physical tests will be conducted on raw materials to determine the optimal proportions of sargassum and soil in different communities for adobe brick production.

For the production of particle boards, sargassum will be combined with local biomasses such as sugarcane bagasse, coconut fiber, and others, using castor oil resin as a binder. Characterization will include bromatological tests, anatomical fiber analysis, and microstructural evaluation via SEM. The panels will undergo thermal pressing and be subjected to standardized tests to compare their performance with international standards.

In addition to physical and mechanical properties, the financial feasibility of the process will be analyzed, considering production costs and market opportunities. Focus groups will be organized within communities to ensure that the developed materials meet local needs, while a market study will identify potential investors and commercialization strategies.

The environmental impact will be assessed through Life Cycle Assessment (LCA), comparing the effects of sargassum’s natural decomposition, landfill disposal, and its incorporation into construction materials. The LCA will be conducted using the GaBi 6 software, following ISO standards, to quantify the environmental benefits of the new materials. The results will be published in scientific journals and integrated into a publicly accessible application, expanding their reach and impact.
