Core Insights - Researchers have developed a 3D printable "living gel" made from photosynthetic cyanobacteria that efficiently removes carbon dioxide from the air [1][2] - This living material requires only sunlight, carbon dioxide, and nutrient-rich artificial seawater for growth, and it can absorb significantly more carbon dioxide than it stores through organic growth [1][2] Group 1 - The new material can absorb approximately 26 milligrams of carbon dioxide per gram over a period of 400 days, with most of it being stored in mineral form [2] - The incorporation of mineral deposits enhances the mechanical strength of the material, allowing it to harden over time [2] - The hydrogel, which serves as the carrier material, is designed to efficiently transmit light, carbon dioxide, water, and nutrients, facilitating uniform distribution of microorganisms [2] Group 2 - This low-energy, environmentally friendly material can sequester carbon dioxide from the atmosphere and may complement existing chemical carbon sequestration processes [2] - Future research will explore the potential of using this material as a coating for building exteriors, enabling continuous carbon sequestration throughout the building's lifecycle [2]
