The Technology Readiness Level (TRL) or Development Stage for seaweed-based construction products varies widely, ranging from niche but commercial products that utilize waste biomass to materials that are still in the early research and development phase. Construction materials are generally categorized as a long-term emerging market opportunity projected to reach a potential market value of $1.4 billion by 2030 (World Bank, 2023).
| Product Type | Company | Development Stage / TRL Context | TRL |
| Adobe Bricks (Sargablocks) | BlueGreen (Mexico) | Small-scale commercial This is the most commercially active product in this category but it’s still at relatively small scale | 8-9 |
| Concrete Blocks (SargaCreto) | Grupo Dakatso de México (Dakatso) | Small-scale commercial. This product is commercially available in Cancun. Sargassum-based concrete is considered the most commercially active product type in this category. | 8-9 |
| Medium Density Fiberboard (MDF) | BlueBlocks | Research and development / pilot. The company currently sells non-load bearing panels to small-scale projects and is establishing its pricing strategy. | 5-6 |
| Nanocellulose (for insulation/hydrogels) | AgriSea | Research and development / pilot. The technology for producing the nanocellulose hydrogel was licensed to AgriSea, and the company is currently building a facility for mass production. | 5-6 |
| Limestone mineralized from macroalgae as cement raw material | Bloomineral | Research and development | 4-5 |
