“Net and Shell: An Integrated Eco-Innovation Transforming Marine Waste into Sustainable Solutions for Coastal Communities” is an innovation that transforms marine waste—such as discarded fishing nets and seashells from the seafood industry, in which Thailand ranks as the world’s third-largest exporter—into sustainable construction materials. The fishing nets are cut into suitable sizes to be used as reinforcing fibers, improving the bonding of binders and enhancing the mechanical properties.
