German newspaper Die Welt visited the Made of Air offices in Berlin to talk to co-founder Daniel Schwaag about the buidling materials of the future:
"Until we have completely switched over to renewable energies, we will have emitted too much CO² to limited global warming to below 2 degrees celsius." He doesn't think everyone will realistically start riding bicycles. Instead we have to actively remove carbon dioxide from the environment. For example, by making buildings out of it. Plants split the carbon dioxide in the air into its components carbon and oxygen. From the carbon they produce sugars and cellulose and build their cells. When they die they emit the carbon again. It combines with oxygen resulting in carbon dioxide or methane.
Carbon can be saved for 1,000 years. "We can sequester the carbon, which the plant removed from the environment, for much longer," Schwaag explains - through controlled controlled carbonizing. The carbon remains sequestered for up to 1,000 years. The process also produces heat. You gain a building material and energy.
