Carbon-Negative Building Material Made of CO2
The Made of Air material is made from waste biomass that has absorbed CO2 during its lifetime (plants naturally absorb CO2 by photosynthesis). It’s baked in an oxygen-free oven to form a stable carbon char – a controlled process that means the material generates negative carbon emissions due to absorbing more carbon dioxide than it emits.
The result is a black, fire-retardant material that can be shaped into panels, reformed and recycled. Although it’s in the early stages of development, the material can be adapted to suit different applications, such as a replacement for fillers in products like plasterboard or for whole material products like cladding tiles.
The studio believes it has the potential to replace existing CO2-producing materials used in the construction industry, such as MDF board, while also acting as a carbon-negative material agent to help cut down the carbon footprint of building projects.
Creatives are increasingly looking to tackle climate change by devising positive solutions that combat pollution. For more pollution-absorbing surfaces, see Considered Environment.
