building material that stores carbon dioxide has bacteria<\/h2>\n

\u00a0<\/p>\n

At ETH Zurich<\/strong><\/a>, scientists develop a building material that is alive and store <\/span>carbon<\/a> dioxide<\/a> from air using growing <\/span>bacteria<\/a> and hydrogel. The research has already been applied to the <\/span>3D printed<\/a> biostructures inside the <\/span>Canada Pavilion<\/a> at the <\/span>Venice Architecture Biennale 2025<\/a> as well as in Dafne\u2019s Skin at the 24th International Exhibition in <\/span>Triennale Milano<\/a>. The team\u2019s goal is to make living materials that can be used for construction and to capture and store carbon dioxide from air using photosynthesis. To achieve this, they combine active cyanobacteria with hydrogel, and as a result, they can shape it using a 3D printer.\u00a0<\/span><\/p>\n

\u00a0<\/p>\n

The living material, then, grows, and as it does, removes the carbon dioxide from the air. The scientists add that the material only needs sunlight, a kind of artificial seawater with nutrients, and carbon dioxide to survive, and because of this, they believe it can be used in architecture to store carbon, which in turn can help fight climate change. The building material that stores carbon can also cause minerals to form with a chemical reaction that happens during photosynthesis. These solid minerals trap the carbon dioxide in a more stable way than biomass does.<\/span><\/p>\n

cyanobacteria is able to form and build up minerals<\/h2>\n

\u00a0<\/p>\n

A reason that the building material that stores carbon dioxide is possible to use for architecture is because as the cyanobacteria is able to form and build up the minerals inside the living object, it becomes harder and stronger eventually, and the structure becomes solid over time. In the published <\/span>study<\/a>, the <\/span>scientists<\/a> document their laboratory tests where they discovered that the building material kept absorbing carbon dioxide for over 400 days, or more than a year. Then, most of the captured carbon was stored as solid minerals inside the material.\u00a0<\/span><\/p>\n

\u00a0<\/p>\n

The scientists have also used hydrogel as the base to mix cyanobacteria with because it is light enough to allow nutrients, and even carbon dioxide, to pass through it and spread out within it evenly. The team turns to 3D printing to shape the building material that stores carbon dioxide, and they\u2019ve also created tailored shapes that allow the light to come inside the object so the nutrients can spread inside and bacteria can stay active for more than a year inside the material. For the scientists, this is a low-energy, eco-friendly way to capture carbon dioxide from the air.<\/span><\/p>\n

Projects where the living material is applied to<\/h2>\n

\u00a0<\/p>\n

Some projects have already started applying the building material that stores carbon dioxide to their works. The first is in Picoplanktonics, which is an exhibition of 3D printed biostructures inside the Canada Pavilion at the Venice Architecture Biennale 2025. Led by Andrea Shin Ling, a doctoral student at ETH Zurich and lead designer of the Living Room Collective, the project uses cyanobacteria on a large scale to capture and store carbon dioxide from the air. It is an example of how the bacteria hardens the structure enough to be used in architecture and construction.<\/span><\/p>\n

\u00a0<\/p>\n

The second is at the 24th International Exhibition at Triennale Milano through an installation called Dafne\u2019s Skin. A collaboration between MAEID Studio and Dalia Dranseike, it is part of a larger exhibition called We the Bacteria: Notes Toward Biotic Architecture, which looks at how living things can be used in architectural design. The structure is covered with wooden shingles where microorganisms are growing on the wood, creating a green layer over time. This green layer, called a patina, is usually a sign of aging or decay, but here it\u2019s part of the design, changing the look of the wood while absorbing carbon dioxide from the air over time.<\/span><\/p>\n<\/p>\n
