ARCHITECT's Ayda Ayoubi reports that Berlin-based think-tank Elegant Embellishments, co-founded by architect Alison Dring and production expert Daniel Schwaag, has developed a biochar-based, carbon-negative building material made of 90% atmospheric carbon dioxide named Made of Air.

The new material uses biomass, an organic waste, which absorbs and stores carbon dioxide. To produce Made of Air, the biomass is baked and stabilized through a pyrolysis (thermal decomposition) process in an oxygen-free oven.

The baked carbon substance is then mixed with a biodegradable binder to create a carbon-negative material that can be molded and shaped into various forms, including façade panels. By the end of its life span, Made of Air can be shredded, and then sequestered in the soil. "Using or consuming products which have sequestered carbon reduces the amount of CO2 in the atmosphere," the company says on its website. "Inverting common assumptions of sustainability that consumption is bad for the environment." [Elegant Embellishments]
