Researchers Propose Using Sargassum Seaweed in Construction Materials

Chetumal, Mexico — Researchers and students at the Instituto Tecnológico de Chetumal have developed an innovative scientific proposal to use sargassum seaweed in the construction industry, creating eco-friendly materials that improve thermal and structural properties of buildings while reducing environmental impact.

Dr. Julio César Cruz Argüello, a professor and researcher at the institution, announced that after months of scientific analysis and laboratory testing, specialists have identified new applications for sargassum as a component in construction materials that are more environmentally friendly.

Thermal Insulation Benefits

Among the most significant benefits is the material’s ability to function as thermal insulation, potentially reducing interior temperatures in homes and businesses by up to seven degrees Celsius.

The researcher explained that one of the main challenges for using sargassum was the presence of heavy metals and salts accumulated during its time in the ocean. However, through a specialized chemical process, they successfully cleaned and treated the raw material to make it suitable for integration into cement mixtures and other construction compounds.

Reduced Concrete Consumption

According to Dr. Cruz Argüello, incorporating processed sargassum into mixtures can reduce the amount of concrete needed for wall and ceiling finishes by up to 30 percent. This represents a sustainable alternative that lowers costs, reduces consumption of traditional materials, and decreases the environmental footprint of housing projects.

He also highlighted that the material’s insulating properties help reflect heat impact, creating cooler spaces in warm climate zones like southern Quintana Roo. This characteristic translates to reduced energy consumption by decreasing the need for constant use of fans or air conditioning systems.

Community Implementation Planned

The specialist indicated that the research team now has complete technical information for manufacturing these new eco-friendly materials and is preparing for a first phase of community implementation. They plan to facilitate processes and share knowledge with coastal residents, specifically in the community of Xcalak, where people will be able to produce these materials for their own use and home improvements.
